So I'm working on my application and I'm simply trying to declare a new array of strings. For some reason it wants an extra bracket to close the class at the end (even though the brackets are fine), and also after "private String[] addSentences = new String[3];" if asks for "{" instead of ";". In other words it wants to close something...I don't get it. Maybe you guys can help.

package org.chinesetones.teacher;

import java.util.ArrayList;
import android.app.Activity;
import android.app.Dialog;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.Gravity;
import android.view.View;
import android.widget.Toast;
import android.view.View;
import android.view.View.OnClickListener;
import org.chinesetones.teacher.Sentence;

public class Game extends Activity implements OnClickListener {
private String[] addStrings = new String[3];
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.game);

// Setup button listeners...
View nextButton = findViewById(R.id.next_button);
nextButton.setOnClickListener(this);
View repeatButton = findViewById(R.id.repeat_button);
repeatButton.setOnClickListener(this);
}
public void onClick(View v){
    switch(v.getId()) {
    case R.id.next_button:
        giveSentence();
        break;
    case R.id.repeat_button:
        playSentence();
        break;
    }
}
private ArrayList<Sentence> sentences;
private String[] addSentences = new String[3];
addSentences[0] = "Hi";
addSentences[1] = "No";
addSentences[2] = "Yes";
}

giveSentence() and playSentence() have not been created yet. The errors are below.

Description Resource Path Location Type Syntax error on token ";", { expected after this token Game.java /ChineseTones/src/org/chinesetones/teacher line 39 Java Problem

Thanks!


You cannot initialize class field that way..

Change

private String[] addSentences = new String[3];
addSentences[0] = "Hi";
addSentences[1] = "No";
addSentences[2] = "Yes";

to

private String[] addSentences = {"Hi", "No", "Yes"};

The other option is to just do

private String[] addSentences = new String[3];

and initialize the array in the class constructor.

public Game()
{
   addSentences[0] = "Hi";
   addSentences[1] = "No";
   addSentences[2] = "Yes";
   ...
}


You can only have declarations outside of methods. So your addSentence assignements

addSentences[0] = "Hi"; 
addSentences[1] = "No"; 
addSentences[2] = "Yes"; 

must either be in a method, constructor, or be part of the declaration.

For a small, statically-defined list like your's, you can do this:

 private String[] addSentences = {"Hi","No","Yes"}; 

If you had a larger initialization list you put that logic into your constructor.

public Game(){
   addSentences[0] = "Hi"; 
   addSentences[1] = "No"; 
   addSentences[2] = "Yes"; 
   ....
}
