Thread: I need help with my homework

Write the Java code of the method Transpose2D that takes one 2-dimentional array (matrix) A and returns one 2-dimentional array B that is transpose of matrix A. (assume that all the rows are of the same length)
and this my answer

public int[][] transpose (int[][] array) {
  if (array == null || array.length == 0)//empty or unset array, nothing do to here
    return array;
 
  int width = array.length;
  int height = array[0].length;
 
  int[][] array_new = new int[height][width];
 
  for (int x = 0; x < width; x++) {
    for (int y = 0; y < height; y++) {
      array_new[y][x] = array[x][y];
    }
  }
  return array_new;
}

is method correct or there an another way to do it
