Hello, this is the JUnit test which I have to pass, below is the code that I have written in my main package;
JUnit Test Class
package main;
import java.util.ArrayList;
import lib.Player;
public class PlayerApp {
public static String execute(ArrayList<Player> players, String fullName) {
players.get(0).setFullPlayerName(fullName);
fullName = "";
for (int i = 0; i <players.size(); i ++) {
if (players.get(i).getName().getFirstName().toLowerCase().contains("a") || players.get(i).getName().getFamilyName().toUpperCase().contains("a")) {
fullName = players.get(i).getName().getFirstName().toLowerCase() + ", " + players.get(i).getName().getFamilyName().toUpperCase() + "\n";
}
System.out.println(fullName);
}
return fullName;
}
}
This is the code in my main package, I am trying to print out the names which contain a char "a" in the first name, the first name should be lowercase and the family name should be uppercase. It should print out
cassie, DOWNTURN
nila, SINGH which is the names with a new line between them, however, when i print it, it prints the following;
cassie, DOWNTURN
cassie, DOWNTURN
nila, SINGH
I am confused as to why cassie, DOWNTURN has been printed twice as i cannot find the error in my code, any help would be greatly appreciated, thank you.
You will print it even if the if doesn't match as it's outside the if-statement. Move it inside instead.
for (int i = 0; i <players.size(); i ++) {
if (players.get(i).getName().getFirstName().toLowerCase().contains("a") || players.get(i).getName().getFamilyName().toUpperCase().contains("a")) {
fullName = players.get(i).getName().getFirstName().toLowerCase() + ", " + players.get(i).getName().getFamilyName().toUpperCase() + "\n";
System.out.println(fullName);
}
}
Your print statement is not conditional and will always execute, move it inside the if. You're printing twice as your are not changing the value in fullName if the if condition does not evaluate as true. Further your family name comparison will always be false as you're comparing upper and lower case.
Your code can also be tided up and made easier to read:
for(Player player : players){
if(player.getName().getFirstName()).toLowerCase().contains("a")||player.getName().getFamilyName().toUpperCase.contains("A"))){
String fullName = players.get(i).getName().getFirstName().toLowerCase() + ", " + players.get(i).getName().getFamilyName().toUpperCase() + "\n";
System.out.println(fullname);
}
}

I few days ago I started messing around with Javas, wanting to create a small tool for League of Legends. Now I encountered a very frustrating error.
indexOf stopped working, but I just can't figure out why. Every time I check the list "players" for the position of the entered name (l1v3 in this case) it just responds with -1. So item not found. Even though is shows up when printing the "players" list.
What did I do wrong? I'm new to coding so thanks for the help in advance!
This is the output I get:

I have the following code which, by means of a keyboard input, gives me the start and arrival .. the start is determined according to the "da" proposition, while the arrival determines it according to the preposition "a" so I'm fighting now is: I want to get the start and the arrival even if I change the order of the propositions .. you know how I could proceed ..
this is the OUTPUT I get :
I want to go from ostuni to trapani
Partenza :ostuni
Arrivo :trapani
but if I wrote like this:
I want to go to ostuni by trapani
I would like to print the same start and finish correctly ..that is
Patenza :trapani
Arrivo :ostuni
Is this processing possible?

I know this will not be considered a good answer:)
This is non-trivial to solve by means of imperative programming. The reason is there are many forms in which one can express the same intent. Things like filler words, synonyms, inversions and in general things you did not think about could disrupt your algorithm.
Of course it depends on the level of accuracy you want to achieve. If you are happy that this will not work for all cases, you could always put in conditions like:
if (arr[index-1] == "from") setStart(arr[index]);
if (arr[index-1] == "to") setDestination(arr[index]);
Google, Amazon and Apple are battling to improve this sort of human-computer interaction, but they are using a more mathematical/statistical approach through machine learning.

The program that I am writing is in Java. I am attempting to make my program read the file "name.txt" and store the values of the text file in an array.
So far I am using a text file that will be read in my main program, a service class called People.java which will be used as a template for my program, and my main program called Names.java which will read the text file and store its values into an array.
name.txt:
John!Doe
Jane!Doe
Mike!Smith
John!Smith
George!Smith
People.java:
public class People
{
String firstname = " ";
String lastname = " ";
public People()
{
firstname = "First Name";
lastname = "Last Name";
}
public People(String firnam, String lasnam)
{
firstname = firnam;
lastname = lasnam;
}
public String toString()
{
String str = firstname+" "+lastname;
return str;
}
}
Names.java:
import java.io.File;
import java.io.IOException;
import java.util.Scanner;
import java.util.StringTokenizer;
public class Names
{
public static void main(String[]args)
{
String a = " ";
String b = "empty";
String c = "empty";
int counter = 0;
People[]peoplearray=new People[5];
try
{
File names = new File("name.txt");
Scanner read = new Scanner(names);
while(read.hasNext())
{
a = read.next();
StringTokenizer token = new StringTokenizer("!", a);
while(token.hasMoreTokens())
{
b = token.nextToken();
c = token.nextToken();
People p = new People(b,c);
peoplearray[counter]=p;
++counter;
}
}
}
catch(IOException ioe1)
{
System.out.println("There was a problem reading the file.");
}
System.out.println(peoplearray[0]);
}
}
As I show in my program, I tried to print the value of peoplearray[0], but when I do this, my output reads: "null."
If the program were working corrrectly, the value of peoplearray[0] should be, "John Doe" as those are the appropriate values in "names.txt"
Is the value of peoplearray[0] supposed to be null?
If not, what can I do to fix this problem?
Thanks!
The order of your arguments is wrong:
StringTokenizer token = new StringTokenizer("!", a);
According to API constructor
public StringTokenizer(String str, String delim)
use
StringTokenizer token = new StringTokenizer(a,"!");

please let me know where am i going wrong and how to fix it.
Thanks
Forget the useDelimiter
List<String> tokens = new ArrayList<String>();
int next = 0;
while (inFile1.hasNext()) {
String line = inFile1.nextLine();
if( next >= tokens.size() ){
tokens.add( line );
} else {
tokens.set( next, tokens.get(next) + line );
}
if( line.endsWith( "$$" ) ) next++;
}
You're issuing a inFile1.nextLine() so naturally, the strings in a[12] and a[13] would be separated.
One approach I can think of is putting the content of the file in a String object, then do a split using "\$\$" .
String s = "Hello$$World$$Sample$$";
for(String sa: s.split("\\$\\$")) {
System.out.println(sa);
}
Output:
Hello
World
Sample
But this will not include the trailing "$$" since you used it in the split. You can easily add that do the end of your string, but this is just one approach.
Hope this helps.
String partialLine = null;
while (inFile1.hasNext()) {
String line = inFile1.nextLine();
if (partialLine != null) {
line = partialLine + line;
partialLine = null;
}
if (line.endsWith("$$") {
tokens.add(line);
} else {
partialLine = line;
}
}
if (partialLine != null) {
// Probably empty line.
}
A bit of buffering: not adding a partial line (missing $$), but keeping it in partialLine.
As you see even several partial lines would work.
I am using cardme library to deal with vcards. Following is my code

}

TelephoneParameterType next1 = telephoneParameterTypes.next();
String type = next1.getType();
TelephoneParameterType next2 = telephoneParameterTypes.next();

System.out.println(type);
System.out.println(type2);
} catch (IOException ex)
{
ex.printStackTrace();
}
}
}
However, there is no method called getNumber() or something. How can I get the mobile numbers and land numbers? Please help!
NOTE: I UPDATED THE CODE. In there, you can see I managed to get the phone number. But, this returns only the HOME phone and not anything else. Even the loop is not stopping. Please help!
I can see
TelephoneFeature.getTelephone()
I'd also suggest taking a look at
TelephoneFeature.getTelephoneParameterTypes()
to see the types
UPDATE
Be careful with the iterators
Each call to vcard.getTelephoneNumbers() is creating a new Iterator, which means you could end up in an infinite loop.
Iterator<TelephoneFeature> itNumbers = vcard.getTelephoneNumbers();
while (itNumbers.hasNext()) {
TelephoneFeature next1 = itNumbers.next();
String telephone = next1.getTelephone();
System.out.println(telephone);
System.out.println("types = " + next1.getExtendedTelephoneParameterSize());
Iterator<XTelephoneParameterType> itTypes = next1.getExtendedTelephoneParameterTypes();
while (itTypes.hasNext()) {
XTelephoneParameterType next = itTypes.next();
System.out.println(" - " + next.getType() + " / " + next.getDescription());
}
}
I stand corrected, the problem (isn't a bug) it's with the tester, not the API :P
If you add
Iterator<TelephoneParameterType> itNTypes = next1.getTelephoneParameterTypes();
while (itNTypes .hasNext()) {
TelephoneParameterType next = itNTypes .next();
System.out.println(" - " + next.getType() + " / " + next.getDescription());
}
to the previous loop, you should get what you're looking for
