Ladder in Java

package CoreJava;

import java.util.Scanner;

public class javaCore {

public static void main (String [] args) {

//this is main function

Scanner scan = new Scanner(System.in);

int age = scan.nextInt();

if (age > 18) {

System.out.print("You are eligible for vote");

}

else if (age == 100) {

System.out.print("You are out dated");

}

else if (age < 18) {

System.out.println("You are not eligible for Vote");

}

//this is called ladder

// else lag gya to ladder khtm

}

}
