This java program is to easily find out largest number in three integers values. But that is not optimize way if numbers are more than that better follow other algorithms.

lass LargestOfThreeNumbers {
public static void main(String args[]) {
int x, y, z;

Scanner in = new Scanner(System.in);
System.out.println("Please Enter First integer");
x = in.nextInt();
System.out.println("Please Enter Second integer");
y = in.nextInt();
System.out.println("Please Enter Third integer");
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.");
}
}

Output

Please Enter First integer
10
Please Enter Second integer
20
Please Enter Third integer
5
Second number is largest.
