Question

10) Create a java program that will ask for name and age with method age where it will check the condition that id you are greater than 18 you can vote.

Answer 1

For the given program, a method checkAge() can be used to check eligibility to vote. The required program and corresponding output are as follows. The code is well commented for better understanding.

import java.util.Scanner;

public class Voting {
  
    public static int checkAge(int a){//cheks for eligibility
          
            int r; 
        if(a>18)//if age greater than 18
                {
                        r=0;
                }
                else
                {
                        r = (18 - a);//else returns difference in age
                } 
                return r;
    }           

        public static void main(String[] args) {
        
        int vote;
                Scanner scan = new Scanner(System.in);
                System.out.println("Enter your Name:");
                String name=scan.nextLine();//reads name
                System.out.println("Enter your Age:");
                int age = scan.nextInt();//reads age
                vote=checkAge(age);//calls function to check age
                System.out.println("Name:"+name);//displays name
                if(vote==0){//checking return value
                        System.out.println("You are eligible to vote.");
                }else{
                        System.out.println("Sorry, you can't vote now! You can vote after :"+ vote + " years");
                }

        }

}

Output:
