That's not the complete rule for an identity matrix. The complete rule is that the matrix contains only 1s on the leading diagonal.

Don't hand this in, your teacher won't like the code style, but ...

boolean isIdentity(int[][] m) {
 boolean isIdentity = true;
 for(int i = 0; i < m.length; i++) for(j = 0; j < m[i].length; j++)
  isIdentity &= m[i][j] == (i == j ? 1 : 0);
 return isIdentity;
}

... I need to get my crazy coding instincts out in a controlled environment now and then Smile | :)
