java program to find largest of three numbers

java program to find largest of three numbers

This java program finds largest of three numbers and then prints it. If the entered numbers are unequal then "numbers are not distinct" is printed.

import java.util.Scanner;

class LargestOfThreeNumbers

{

public static void main(String args[])

{

int x, y, z;

System.out.println("Enter three integers ");

Scanner in = new Scanner(System.in);

x = in.nextInt();

y = in.nextInt();

z = in.nextInt();

if ( x > y && x > z )

System.out.println("First number is largest.");

else if ( y > x && y > z )

System.out.println("Second number is largest.");

else if ( z > x && z > y )

System.out.println("Third number is largest.");

else

System.out.println("Entered numbers are not distinct.");

}

}
