Converting array to String

[Ant_Magma]

I have a 2 dimensional array, screen[][] which i want to convert into String and print.

	
public String toString(){
		String z=z.copyValueOf(screen);
		return z;
	}

I know the code above is wrong, how should i code it?

[sjalle]

StringBuffer sb=new StringBuffer();
public String toString(){
  sb.setLength(0);
  for (int i=0; i<screen.length; i++) {
    for (j=0; j<screen[i].length; j++) {
      sb.append(screen[i][j]);
    }
  }
  return sb.tostriing();
}
