Write arrayList< model class> into txt file using BufferedWriter

I'm trying to get the data from the arrayBundlePack after getting data from enqueue call, I'm trying to use BufferedWriter to the saved data in the arrayBundlePack & write in the txt file, but it just won't get the output I wanted.
I'm not sure if that's the way to output an arrayList model class.
Here's the code
private ArrayList<BundlePack> arrayBundlePack;
Call<BundlePackRepo> call = .............. // api content
call.enqueue(new Callback<BundlePackRepo>() {
#Override
public void onResponse(Call<BundlePackRepo> call, retrofit2.Response<BundlePackRepo> response) {
if (response.isSuccessful()) {
BundlePackRepo repos = response.body();
BundlePackRepo.bundlepacks[] bundlePacksarray;
bundlePacksarray = repos.getBundlePacks();
BundlePack bundlePack;
for (int a = 0; a < bundlePacksarray.length; a++) {
bundlePack = new BundlePack();
bundlePack.setPromotion_kit(bundlePacksarray[a].getPromotion_kit());
bundlePack.setStock_code(bundlePacksarray[a].getStock_code());
bundlePack.setIssue_ref(bundlePacksarray[a].getIssue_ref());
bundlePack.setQuantity(bundlePacksarray[a].getQuantity());
String sysMod = bundlePacksarray[a].getSys_mod();
String modifyDate = bundlePacksarray[a].getModify_dt();
try {
bundlePack.setSys_mod(df.parse(sysMod));
bundlePack.setModify_dt(df.parse(modifyDate));
} catch (java.text.ParseException e) {
e.printStackTrace();
}
bundlePack.setStatus(bundlePacksarray[a].getStatus());
arrayBundlePack.add(bundlePack);
//Trying to put out the data to text file
String filename = "bundlepack.txt";
File txtData = new File(getApplicationContext().getFilesDir(), filename);
FileWriter txtWriter = null;
try {
txtWriter = new FileWriter(txtData);
BufferedWriter fileWriter = new BufferedWriter(txtWriter);
for (BundlePack bdpack : arrayBundlePack) {
fileWriter.write(bdpack.toString());
fileWriter.newLine();
fileWriter.flush();
}
} catch (IOException e) {
e.printStackTrace();
}
}

You are calling toString() to convert each bundlepack instance to a string for output. So you need to an override for toString to the bundlepack class. It needs to format the instance in the form that you need for your purposes.
Since you currently haven't overridden that method, your code is currently calling Object.toString() ... which only outputs the object's class name and hashcode.
Your IDE may well have a helper to generate a toString for a class, based on the fields of the class.

how to increment the id value when Json data enter in postman without db using in java play framework ? can anyone help how to generate id values

public class MovieController extends Controller {
public static List<Movie> movies;
static {
movies = new ArrayList<>();
movies.add(new Movie(1, "dsfnejhf", "Movie on Racing", "abcd", "xyz"));
movies.add(new Movie(2, "F2", "Comedy Movie", "Venkatesh", "Tamanna"));
movies.add(new Movie(3, "Titanic", "Movie", "Hero", "Heroine"));
movies.add(new Movie(4, "Saaho", "action", "Prabhas", "Shradda kapoor"));
movies.add(new Movie(5, "Bhahubali 1", "action", "Prabhas", "Tamanna"));
}
public Result insert(Http.Request request) {
JsonNode jsonNode = request.body().asJson();
if (jsonNode == null) {
return badRequest("insufficient movie information");
}
Movie movie = Json.fromJson(jsonNode, Movie.class);
movies.add(movie);
return ok(Json.toJson(movie));
}
this is Movie class and above MovieController class now how to write code for increment of id value from existing id number
public class Movie {
private int id;
private String movieName;
private String description;
private String hero;
private String heroine;
public Movie(int id, String movieName, String description, String hero, String heroine) {
this.id = id;
this.movieName = movieName;
this.description = description;
this.hero = hero;
this.heroine = heroine;
}
public Result getMoviesById(int id) {
Movie movie = findById(id);
if (movie == null) {
return notFound("movie not found");
}
return ok(Json.toJson(movie));
}

Just get the maximum id from the movies list (0 for a empty list) and increase this with 1
int maxId = movies.stream()
.mapToInt(m -> m.getId())
.max()
.orElse(0);
int nextId = maxId + 1;
an example with a mimimal MovieController:
import java.util.ArrayList;
import java.util.List;
public class MovieController {
public static List<Movie> movies;
static {
movies = new ArrayList<>();
movies.add(new Movie(1, "dsfnejhf", "Movie on Racing", "abcd", "xyz"));
movies.add(new Movie(2, "F2", "Comedy Movie", "Venkatesh", "Tamanna"));
movies.add(new Movie(3, "Titanic", "Movie", "Hero", "Heroine"));
movies.add(new Movie(4, "Saaho", "action", "Prabhas", "Shradda kapoor"));
movies.add(new Movie(5, "Bhahubali 1", "action", "Prabhas", "Tamanna"));
}
public Movie insert(Movie movie) {
int maxId = movies.stream()
.mapToInt(m -> m.getId())
.max()
.orElse(0);
movie.setId(++maxId);
movies.add(movie);
return movie;
}
public static void main(String[] args) {
MovieController mc = new MovieController() ;
System.out.println("start---");
for (Movie m : movies) {
System.out.println(m);
}
Movie newMovie = new Movie(-1,"aa","bb", "h1", "h2");
newMovie = mc.insert(newMovie);
System.out.println("after insert---");
for (Movie m : movies) {
System.out.println(m);
}
}
}
and a minimal Movie:
public class Movie {
private int id;
private String movieName;
private String description;
private String hero;
private String heroine;
public Movie(int id, String movieName, String description, String hero, String heroine) {
this.id = id;
this.movieName = movieName;
this.description = description;
this.hero = hero;
this.heroine = heroine;
}
public Movie getMoviesById(int id) {
Movie movie = findById(id);
if (movie == null) {
return null;
}
return movie;
}
private Movie findById(int id) {
return null;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
#Override
public String toString() {
return "Movie{" +
"id=" + id +
", movieName='" + movieName + '\'' +
", description='" + description + '\'' +
", hero='" + hero + '\'' +
", heroine='" + heroine + '\'' +
'}';
}
}
It will add a movie to the list with id 6.

How to print all DirectorNames or ProducerNames etc alphabetically reading from a text file

public void alphabeticalListing()
{
BufferedReader br = null;
List<String> lineList = new ArrayList<String>();
try
{
br = new BufferedReader(new FileReader(wishlistname + ".txt"));
String line;
while((line = br.readLine())!=null)
{
lineList.add(line);
}
Collections.sort(lineList);
for(String output : lineList) {
System.out.println(output);
}
}
catch(Exception e)
{
e.printStackTrace();
}
}
The file Contains Movie Details...
Example:
MovieName:DirectorName:ProducerName:Rating:Review
Terminator: Arfath: Khalid : 8 : VeryGood
Hangover : John : Lucas : 7 : NotBad
Jumanji : Rock : Brock : 9 : Good
I want to select ProducerName Column and do SOP in alphabetically like,
Output:
Brock
Khalid
Lucas

You can use java Compartor for sorting by creating Movie as model class. You can achieve this using below code:
public static void readDataFromFile(String filePath) throws FileNotFoundException
{
List<Movie> movies = new ArrayList<Movie>();
File file = new File(filePath);
Scanner sc = new Scanner(file);
while (sc.hasNextLine())
{
String txtLine = sc.nextLine();
//Extract data from single from txt file row
String[] data = txtLine.split(":");
Movie movie = new Movie(data[0], data[1], data[2], data[3], data[4]);
//Add to movies list
movies.add(movie);
}
System.out.println("Unsorted-----------");
System.out.println(movies);
System.out.println("Sorting by director-----------");
Collections.sort(movies, new DirectorSorter());
System.out.println(movies);
System.out.println("Sorting by producer-----------");
Collections.sort(movies, new ProducerSorter());
System.out.println(movies);
}
public static class Movie
{
private String name;
private String director;
private String producer;
private String rating;
private String review;
public Movie(){}
public Movie(String name, String director, String producer, String rating, String review){
this.name = name;
this.director = director;
this.producer = producer;
this.rating = rating;
this.review = review;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDirector() {
return director;
}
public void setDirector(String director) {
this.director = director;
}
public String getProducer() {
return producer;
}
public void setProducer(String producer) {
this.producer = producer;
}
public String getRating() {
return rating;
}
public void setRating(String rating) {
this.rating = rating;
}
public String getReview() {
return review;
}
public void setReview(String review) {
this.review = review;
}
#Override
public String toString() {
return "Movie : " + name + " - " + director + " - " + producer + " - " + rating + " - " + review + "\n";
}
}
public static class DirectorSorter implements Comparator<Movie>{
#Override
public int compare(Movie o1, Movie o2) {
return o1.getDirector().compareTo(o2.getDirector());
}
}
public static class ProducerSorter implements Comparator<Movie>{
#Override
public int compare(Movie o1, Movie o2) {
return o1.getProducer().compareTo(o2.getProducer());
}
}

Return more that one ArrayList

I'm trying to deal with this baking JSON:
in android app so this is the class to bring the JSON data from link:
OpenBakingJsonUtils.java:
public final class OpenBakingJsonUtils {
public static ArrayList<ArraysLists> getSimpleBakingStringsFromJson(Context context, String bakingJsonString)
throws JSONException {
final String ID = "id";
final String NAME = "name";
final String SERVINGS = "servings";
final String INGREDIENTS = "ingredients";
final String STEPS = "steps";
final String QUANTITY = "quantity";
final String MEASURE = "measure";
final String INGREDIENT = "ingredient";
final String IDSTEPS = "id";
final String SHORTDESCRIPTION = "shortDescription";
final String DESCRIPTION = "description";
final String VIDEOURL = "videoURL";
final String THUMBNAILURL = "thumbnailURL";
ArrayList<ArraysLists> parsedRecipeData = new ArrayList<ArraysLists>();
ArrayList<BakingItem> Baking = new ArrayList<BakingItem>();
JSONArray recipeArray = new JSONArray(bakingJsonString);
for (int i = 0; i < recipeArray.length(); i++) {
int id;
String name;
int servings;
double quantity;
String measure;
String ingredient;
int idSteps;
String shortDescription;
String description;
String videoURL;
String thumbnailURL;
JSONObject recipeObject = recipeArray.getJSONObject(i);
id = recipeObject.getInt(ID);
name = recipeObject.getString(NAME);
servings = recipeObject.getInt(SERVINGS);
ArrayList<IngredientsItem> Ingredients = new ArrayList<IngredientsItem>();
JSONArray ingredientsArray = recipeObject.getJSONArray(INGREDIENTS);
for(int j = 0 ; j< ingredientsArray.length(); j++) {
JSONObject ingredientsObject = ingredientsArray.getJSONObject(j);
quantity = ingredientsObject.getDouble(QUANTITY);
measure = ingredientsObject.getString(MEASURE);
ingredient = ingredientsObject.getString(INGREDIENT);
Ingredients.add(new IngredientsItem(quantity, measure, ingredient));
}
ArrayList<StepsItem> Steps = new ArrayList<StepsItem>();
JSONArray stepsArray = recipeObject.getJSONArray(STEPS);
for(int j = 0 ; j< stepsArray.length(); j++) {
JSONObject stepsObject = stepsArray.getJSONObject(j);
idSteps = recipeObject.getInt(IDSTEPS);
shortDescription = stepsObject.getString(SHORTDESCRIPTION);
description = stepsObject.getString(DESCRIPTION);
videoURL = stepsObject.getString(VIDEOURL);
thumbnailURL = stepsObject.getString(THUMBNAILURL);
Steps.add(new StepsItem(idSteps, shortDescription, description, videoURL, thumbnailURL));
}
Baking.add(new BakingItem(id, name, servings, Ingredients, Steps));
parsedRecipeData.add(new ArraysLists(Baking, Ingredients, Steps));
}
return parsedRecipeData;
}
}
as you see there are 3 ArrayList classes:
ArrayList<BakingItem>
ArrayList<IngredientsItem>
ArrayList<StepsItem>
and this is the code for each one:
BakingItem.java:
public class BakingItem implements Parcelable {
private int id;
private String name;
private int servings;
private ArrayList<IngredientsItem> ingredients = new ArrayList<IngredientsItem>();
private ArrayList<StepsItem> steps = new ArrayList<StepsItem>();
public BakingItem(int id, String name, int servings, ArrayList<IngredientsItem> ingredients, ArrayList<StepsItem> steps) {
this.id = id;
this.name = name;
this.servings = servings;
this.ingredients = ingredients;
this.steps = steps;
}
#Override
public void writeToParcel(Parcel out, int flags) {
out.writeInt(id);
out.writeString(name);
out.writeInt(servings);
out.writeTypedList(ingredients);
out.writeTypedList(steps);
}
private BakingItem(Parcel in) {
this.id = in.readInt();
this.name = in.readString();
this.servings = in.readInt();
ingredients = new ArrayList<IngredientsItem>();
in.readTypedList(ingredients, IngredientsItem.CREATOR);
}
public BakingItem() {
}
#Override
public int describeContents() {
return 0;
}
public static final Parcelable.Creator<BakingItem> CREATOR = new Parcelable.Creator<BakingItem>() {
#Override
public BakingItem createFromParcel(Parcel in) {
return new BakingItem(in);
}
#Override
public BakingItem[] newArray(int i) {
return new BakingItem[i];
}
};
public int getId() {
return id;
}
public String getName() {
return name;
}
public int getServings() {
return servings;
}
}
IngredientsItem.java:
public class IngredientsItem implements Parcelable {
private double quantity;
private String measure;
private String ingredient;
public IngredientsItem(double quantity, String measure, String ingredient) {
this.quantity = quantity;
this.measure = measure;
this.ingredient = ingredient;
}
#Override
public void writeToParcel(Parcel out, int flags) {
out.writeDouble(quantity);
out.writeString(measure);
out.writeString(ingredient);
}
private IngredientsItem(Parcel in) {
this.quantity = in.readDouble();
this.measure = in.readString();
this.ingredient = in.readString();
}
public IngredientsItem() {
}
#Override
public int describeContents() {
return 0;
}
public static final Parcelable.Creator<IngredientsItem> CREATOR = new Parcelable.Creator<IngredientsItem>() {
#Override
public IngredientsItem createFromParcel(Parcel in) {
return new IngredientsItem(in);
}
#Override
public IngredientsItem[] newArray(int i) {
return new IngredientsItem[i];
}
};
public double getQuantity() {
return quantity;
}
public String getMeasure() {
return measure;
}
public String getIngredient() {
return ingredient;
}
}
as well as the StepsItem class
and the forth is the ArraysLists.java which contain all the 3 arrays above and returned by the OpenBakingJsonUtils.java:
Then I'm trying to call these JSON data in different activities
so in MainActivity.java in loadInBackground:
Override
public ArrayList<BakingItem> loadInBackground() {
URL recipeRequestUrl = NetworkUtils.buildUrl();
try {
String jsonBakingResponse = NetworkUtils.getResponseFromHttpUrl(recipeRequestUrl);
ArrayList<ArraysLists> simpleJsonBakingData = OpenBakingJsonUtils.getSimpleBakingStringsFromJson(MainActivity.this, jsonBakingResponse);
return simpleJsonBakingData;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
I call the returned ArrayList from OpenBakingJsonUtils.java which is in this case the ArraysLists,
then in DetailActivity.java in doInBackground:
#Override
protected ArrayList<ArraysLists> doInBackground(Object... params) {
if (params.length == 0) {
return null;
}
URL reviewsRequestUrl = NetworkUtils.buildUrl();
try {
String jsonReviewResponse = NetworkUtils.getResponseFromHttpUrl(reviewsRequestUrl);
ArrayList<ArraysLists> simpleJsonReviewData = OpenBakingJsonUtils.getSimpleBakingStringsFromJson(DetailsActivity.this, jsonReviewResponse);
return simpleJsonReviewData;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
here I call the ArrayList of ArraysLists too but the problem in adapters of MainActivity.java and DetailsActivity.java in onBindViewHolder:
holder.CommentContent.setText(String.valueOf(mCommentsItems.get(position).getQuantity()));
it just says that cannot resolve method getQuantity() which is in IngredientsItem.java while I used the ArraysLists.java that returned by OpenBakingJsonUtils.java
so what should I do to call methods from BakingItem.java and IngredientsItem.java while I use the returned ArraysLists.java ?

Try to put some order on your code because is not easy read it. Also, create a method where you can inicialite your widgets, something like this:
public static void startCom(){
text1 = (textView) findById....
.
.
.
}
Only on the method onCreate you invoke startComp, just to save the order of the code.
