Parsing from MealMaster files in Java

Currently, I'm am trying to parse from MealMaster files, but I am having an issue where Ingredients are being parsed as:
"Inch thick" due to the next line not having a quantity or unit, and carrying on from the previous
Also, I'm finding ingredients that are listed as "ingredient1 or ingredient2" and I'm not sure how to catagorise these in the parser
Here is an example of a file I'm parsing from and my code below
https://pastebin.com/fhkRczya
public void readIngredients() {
try {
Remover remover = new Remover();
ArrayList<Ingredient> ing = new ArrayList<Ingredient>();
while(!( "".equals(line.trim()))) {
parsedIngredients = line + "\n";
if(!line.contains("---") && !line.contains(":")) {
Ingredient currentIng = splitLine();
if(currentIng.getQuantity().length() == 0 && !ing.isEmpty()) {
Ingredient lastIng = ing.get(ing.size()-1);
if (currentIng.getName().toLowerCase().contains("inch") ) {
//System.out.println(currentIng.getName());
lastIng.setOther(lastIng.getOther() + "," + currentIng.getQuantity() + "," +currentIng.getName());
//System.out.println("OTher " + lastIng.getOther());
}else{
String lastIngName = lastIng.getName();
String addName = lastIngName + " " + currentIng.getName();
lastIng.setName(addName);
lastIng = remover.removeTo(unitWords,lastIng);
lastIng = remover.removeCustomWords(lastIng);
}
}else if (currentIng.getName().startsWith("-") || currentIng.getName().startsWith("For") ){
if(ing.size()>0) {
Ingredient lastIng = ing.get(ing.size()-1);
lastIng.setOther(currentIng.getQuantity() + " " + currentIng.getName());
}
}else {
currentIng = remover.removeTo(unitWords,currentIng);
currentIng = remover.removeCustomWords(currentIng);
//currentIng.setName(currentIng.getName().replace(",", ""));
System.out.println(currentIng.getName());
ing.add(currentIng);
}
}
line = reader.readLine();
}
for(int i = 0; i < ing.size();i++) {
removeCommaColon(ing.get(i));
}
for(int i = 0; i<ing.size();i++) {
ingredientsString = ingredientsString + ing.get(i).getName() + "|" + currentRecipe.getTitle() + " \n";
//ingredientsString = ingredientsString + currentRecipe.getTitle() + "\n";
}
currentRecipe.setIngredients(ing);
} catch (IOException e) {

Creating a jsp search form to run a java Search program

The background info here is that I have a working Indexer and Search (in java) that indexes and searches a file directory for the filenames and then copies the files to a "Results" Directory.
What I need/ don't have much experience in is writing jsp files. I need the jsp file to have a search bar for the text and then a search button. When text is entered in the bar, and the button is clicked, I need it to run my search program with the entered text as an arg.
I have added the IndexFiles and the SearchFiles classes for reference.
Please explain with a good example if you can help out!

First, you should definitely do this in a servlet rather than a JSP. Putting lots of logic in JSP is bad practice. (See the servlets info page).
Second, it would probably be better on performance to make a cronjob (Linux) or Task (Windows) to run the search program every hour and store the results in a database and just have your servlet pull from there rather than allow the user to initiate the search program.

Splitting String based on this six characters 0102**

I recommend checking out the Java documentation, it provides a really good reference to start with. The .split method uses a regex to split up a string based on a delimiter.
String[] tokens = myString.split("0102\\*\\*");

For now I suspect that you forgot to escape * in split regex.
Try maybe
String[] resutl = yourString.split("0102\\*\\*");
In case you want * to represent any character then use . instead of *
String[] resutl = yourString.split("0102..");
In case you want * to represent any digit use \\d instead
String[] resutl = yourString.split("0102\\d\\d");

String string = "blabla0102**dada";
String[] parts = string.split("0102\\*\\*");
String part1 = parts[0]; // blabla
String part2 = parts[1]; // dada
Here we have a String: "blabla0102**dada", we call it string. Every String object has a method split(), using this we can split a string on anything we desire.

Do you mean literally split by "0102**"? Couldn't you use regex for that?
String[] tokens = "My text 0102** hello!".split("0102\\*\\*");
System.out.println(tokens[0]);
System.out.println(tokens[1]);

Converting working code into a recursive method

Hi guys I needed to create a method to display current directory, files, subdirectories and the files of those subdirectories given a file the user has to choose. I accomplished the task and the fallowing code is printing the appropriated output. It is printing from the f.getParentFile() down, that is what want. Now I want to use recursion instead. I am trying to learn the concept of recursion. I know you need a base case and then your inductive step, but when I try to modify my code into recursive I get an infinite loop when it hits the first subdirectory. Any feedback will be appreciated.
NON-Recursive Working code
static void listFiles(File f)
{
try
{
if (f.exists())
{
File dir = f.getParentFile();
if (dir.isDirectory())
{
System.out.println("Directory: " + dir );
File[] list = dir.listFiles();
for (int i = 0; i < list.length; i++)
{
if (list[i].isDirectory())
{
System.out.println("\tSubdirectory: " + list[i].getName() + "\tsize :" + (list[i].length()/1024) + "KB" );
File[] listFiles = list[i].getAbsoluteFile().listFiles();
for (int j = 0; j < listFiles.length; j++)
{
System.out.println("\t\tSubdirectory files: " + listFiles[j].getName() + "\tsize :" + (listFiles[j].length()/1024) + "KB" );
}
}
else if (list[i].isFile())
{
System.out.println("\tFiles: " + list[i].getName() + "\tsize :" + (list[i].length()/1024) + "KB" );
}

}
}
else throw new FileNotFoundException("File ******** does not exists");

It is really really simple :)

Java: Please insert "}" to complete classbody

I wrote a little test program but I'm experiencing a syntax error in my closing tags...
Here's the code
public class Test
{
AudioFile file = null;
String vbb = "";
File f;
public Test()
{
openFile();
}
public File openFile()
{
JFileChooser fc = new JFileChooser();
fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
int result = fc.showOpenDialog(fc);
if(result == JFileChooser.CANCEL_OPTION)
{
return null;
} else {
f = fc.getCurrentDirectory();
return f;
}
}
f = new File(openFile());
File[] files = f.listFiles();
for(File fi : files)
{
try {
file = (AudioFile) AudioFileIO.read(new File(fi.getAbsolutePath()));
MP3AudioHeader ah = (MP3AudioHeader) file.getAudioHeader();
String time = ah.getTrackLengthAsString();
String rate = ah.getBitRate();
boolean vb = ah.isVariableBitRate();
if(vb == false)
{
vbb = "Nee";
} else {
vbb = "Ja";
}
Tag tag = file.getTag();
String artist = tag.getFirst(FieldKey.ARTIST);
String title = tag.getFirst(FieldKey.TITLE);
String album = tag.getFirst(FieldKey.ALBUM);
String genre = tag.getFirst(FieldKey.GENRE);
String temo = tag.getFirst(FieldKey.BPM);
String path = fi.getAbsolutePath();
System.out.println("Duur: " + time + "\nVariabele bitrate: " + vbb + "\nArtiest: " + artist +"\nTitel: " + title
+ "\nAlbum: " + album + "\nGenre: " + genre + "\nBPM: " + temo + "\nBitrate: " + rate + " kbps\nPad: " + path);
} catch (Exception e)
{
System.err.print("FOUT");
}
}
}
The compiler gives an error at the LATEST closing accolade:
"Please insert } to complete classbody"
And also at the last accolade of the "openFile()" method...
Any suggestions?

f = new File(openFile());
File[] files = f.listFiles();
for(File fi : files)
{
//...
}
This whole block of logic is not in a method. It needs to be in a method or constructor.

Where you have
f = new File ...
...
catch ( .. )
{
....
}
You want to wrap that in
public static void main (String args[]) {
....
}
You cannot have a code block in a class definition. At the very top of the class, those variable declarations are declarations of class members with default visibility.

All the code starting with the line
f = new File(openFile());
is outside of any method. This is not legal Java: statements must be enclosed in a block or method body.

everything below
public File openFile()
{
JFileChooser fc = new JFileChooser();
fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
int result = fc.showOpenDialog(fc);
if(result == JFileChooser.CANCEL_OPTION)
{
return null;
} else {
f = fc.getCurrentDirectory();
return f;
}
}
is not enclosed within a method body but is rather lurking in the class body. remove the outer closing brace above.

Your code is not in a method. It needs to be in a method or a static block. Guessing your intent you can put it in the constructor like :
public class Test
{
AudioFile file = null;
String vbb = "";
File f;
public Test()
{
openFile();
f = new File(openFile());
File[] files = f.listFiles();
for(File fi : files)
{
try {
file = (AudioFile) AudioFileIO.read(new File(fi.getAbsolutePath()));
MP3AudioHeader ah = (MP3AudioHeader) file.getAudioHeader();
String time = ah.getTrackLengthAsString();
String rate = ah.getBitRate();
boolean vb = ah.isVariableBitRate();
if(vb == false)
{
vbb = "Nee";
} else {
vbb = "Ja";
}
Tag tag = file.getTag();
String artist = tag.getFirst(FieldKey.ARTIST);
String title = tag.getFirst(FieldKey.TITLE);
String album = tag.getFirst(FieldKey.ALBUM);
String genre = tag.getFirst(FieldKey.GENRE);
String temo = tag.getFirst(FieldKey.BPM);
String path = fi.getAbsolutePath();
System.out.println("Duur: " + time + "\nVariabele bitrate: " + vbb + "\nArtiest: " + artist +"\nTitel: " + title
+ "\nAlbum: " + album + "\nGenre: " + genre + "\nBPM: " + temo + "\nBitrate: " + rate + " kbps\nPad: " + path);
} catch (Exception e)
{
System.err.print("FOUT");
}
}
}
public File openFile()
{
JFileChooser fc = new JFileChooser();
fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
int result = fc.showOpenDialog(fc);
if(result == JFileChooser.CANCEL_OPTION)
{
return null;
} else {
f = fc.getCurrentDirectory();
return f;
}
}
}
