Here is the code that will help to get the largest number.
import java.util.Scanner;
class BigNum
{
public static void main(String args[])
{
int a, b, c, d;
System.out.println("To get the largest among different numbers: ");
System.out.println();
System.out.println("Enter three integers: ");
Scanner in = new Scanner(System.in);
a = in.nextInt();
b = in.nextInt();
c = in.nextInt();
d = in.nextInt();
if ( a > b && a > c && a > d)
System.out.println("1st number is largest.");
else if ( b > a && b > c && b > d)
System.out.println("2nd number is largest.");
else if ( c > a && c > b && c > d)
System.out.println("3rd number is largest.");
else if ( d > a && d > b && d > c)
System.out.println("4th number is largest.");
else
System.out.println("Entered numbers are not different.");
}
