Write the body of the method getLargest. The method writes the largest number out of three integers. If two or more equal largest integers are passed to the method, the output of the program should be “Enter unique numbers!”. If your method works correctly, the output of the following program will be 7. Test your method by passing the following set of parameters to it.

  1. mc.getLargest(2, 6, 11);
    The output should be 11.
  2. mc.getLargest(44, 123, 123);
    The output should be “Enter unique numbers!”.
  3. mc.getLargest(21, 22, 21);
    The output should be 22.

Answer explanation

The body of the method is written in the following code.

public class MyClass
{
  void getLargest(int i, int i2, int i3)
  {
    if(i > i2 && i > i3)
      System.out.println(i);
    else if(i2 > i && i2 > i3)
      System.out.println(i2);
    else if(i3 > i && i3 > i2)
      System.out.println(i3);
    else System.out.println(""
        + "Enter unique numbers!");
  }
  public static void main(String[] args)
  {
    MyClass mc = new MyClass();
    mc.getLargest(-9, 7, 1);
    mc.getLargest(2, 6, 11);
    mc.getLargest(44, 123, 123);
    mc.getLargest(21, 22, 21);
  }
}
