Thread: Two-dimensional boolean array?

Hi,
I'a beginner in Java language. I saw the following exercise from the following web:
http://introcs.cs.princeton.edu/14array/
I tryied to solve it, but can't get it. Please help .

Write a code fragment that prints the contents of a two-dimensional boolean array, using * to represent true and a space to represent false. Include row and column numbers.

below is my effort....

public void 2Ddisplay() {
    	for (int x = 0; x < 2Darray[0].length; x++) {
    	for (int y = 0; y < 2Darray.length; y++) {
    	if (pixels[x][y] == true) {
    	System.out.println("*");
    	} else {
    	System.out.println(" ");
    	}
 
 
    	}
    	}
    }
boolean 2Darray[][];
int w,h;

Thank you

There's only a 2 possible values, therefore a 2d boolean array will work perfectly fine (not to mention that the problem specifically says to represent the contents of a 2d boolean array as such ).

You say you can't get it, what did you mean by that statement? Are your outputs wrong? Or are you getting an exception/compile error? If so, please post the message.

One thing I can see right away is that you're printing out each element on it's own line. You might want to consider using System.out.print to print out a row, then use an empty System.out.println to advance to the next row.
