Problem in reading a file into 2-D array

[matrixcool]

Hello,

I have a file and this how it looks like:

6
{a, b, c, d, e, f}
1 1 1 0 0 0
0 1 1 0 0 0
0 0 1 0 0 0
0 0 1 1 0 0
0 1 1 1 1 0
1 1 1 1 1 1

6 is the number of elements in the set and {a, b, c, d, e, f} is the list of set members and the matrix is the relation matrix.

I'm trying to read the file and store the matrix in 2-D array but when I print the matrix it prints zeros but with the correct size ! and this is my whole code:

import java.util.*;
import java.io.*;
//import java.io.FileInputStream;
//import java.io.FileNotFoundException;

public class Test1 {

    public static void main(String[] args) {

    	Scanner key= new Scanner (System.in);
    	System.out.println("Enter the name of the file: ");
    	String name=key.next();

    	Scanner inputStream=null;
    	try{
    		inputStream= new Scanner(new FileInputStream(name));
    	}
    	catch(FileNotFoundException e)
    	{
    		System.out.println("File"+name+" is not found!");
    		System.out.println("or couldn't be opened!");
    		System.exit(0);
    	}
    	int size=0;
    	if (inputStream.hasNext()){
    		size= inputStream.nextInt();
    		inputStream.nextLine();


    	}
    	else{
    		System.out.println("The Size of the matrix is not clearly stated!");
    	}

    	int array[][]=new int[size][size];


    	while (inputStream.hasNextInt()){
    			for (int i=0;i<array.length;i++){
    				for (int j=0;j<array[i].length;j++){
    					array[i][j]=inputStream.nextInt();
						inputStream.next();

    			}



    		}


    	}
    	inputStream.close();
    	 for (int i = 0; i < array.length; i++) {
            for (int j = 0; j <array[i].length; j++){

                System.out.print(array[i][j]);
                System.out.print(" ");
            } System.out.println();
        }
    }


    }

Could any one please tell me why the output is zeros but the size of the matrix is correct !

Try debugging your code by adding printlns to show that you are reading in any numbers. Print out the numbers as you read them in.

I read the file into 2-D array and then printed it but the output is turned out to be zeros !

Print out the numbers as you read them in.

I tried this code and it doesn't print anything:

while (inputStream.hasNextInt()){
    			for (int i=0;i<array.length;i++){
    				for (int j=0;j<array[i].length;j++){
    					array[i][j]=inputStream.nextInt();
						System.out.print(array[i][j] + " ");
						inputStream.next();

    			}



    		}


    	}

it doesn't print anything:

That means that the code is not being executed.
What controls if the code in the loop will be executed?
Print out the condition being tested in the while statement.

Could you correct my code because I didn't understand your lasr reply

What is inside of the ()s in the while statement? It's called a conditional expression.
Is the expression true or false?
Write a print statement that prints out its value to see.
