Question

It is homework question.

Question:

“Use an array of integers with size 10 and print the content of the array using write( ) method.

Note: Please do not use System.out.println( ) method.”

This is what I have tried so far, but it doesn’t work.

int i = 0;
while (i != array.length) {
  byte[] temp = new byte[4];
  temp[0] = (byte) (array[i] & 256);
  array[i] = array[i] >> 8;
  temp[1] = (byte) (array[i] & 256);
  array[i] = array[i] >> 8;
  temp[2] = (byte) (array[i] & 256);
  array[i] = array[i] >> 8;
  temp[3] = (byte) (array[i] & 256);
  System.out.write(temp, 0, 4);
  i++;
}

I can’t find a way to do this, please help me out.

Thanks in advance. 🙂

Answer 1

void printInt(int x) {
  String s = String.valueOf(x);
  for(int i = 0; i < s.length(); i++) {
     System.out.write(s.charAt(i));
  }
  System.out.write('\n');
}

Edit: prettier:

void printInt(int x) {
  String s = String.valueOf(x);
  System.out.write(s.getBytes());
  System.out.write('\n')
}
