Question

1. Write an if-else statement to describe an object. Print "Balloon" if isBalloon is true and isRed is false. Print "Red balloon" if isBalloon and isRed are both true. Print "Not a balloon" otherwise. End with newline.

import java.util.Scanner;

public class RedBalloon {
   public static void main (String [] args) {
      Scanner scnr = new Scanner(System.in);
      boolean isRed;
      boolean isBalloon;

      isRed = scnr.nextBoolean();
      isBalloon = scnr.nextBoolean();

      /* Your solution goes here */

   }
}

2. Assign isTeenager with true if kidAge is 13 to 19 inclusive. Otherwise, assign isTeenager with false.

import java.util.Scanner;

public class TeenagerDetector {
   public static void main (String [] args) {
      Scanner scnr = new Scanner(System.in);
      boolean isTeenager;
      int kidAge;

      kidAge = scnr.nextInt();

      /* Your solution goes here */

      if (isTeenager) {
         System.out.println("Teen");
      }
      else {
         System.out.println("Not teen");
      }
   }
}

public class RedBalloon {
    public static void main (String [] args) {
        Scanner scnr = new Scanner(System.in);
        boolean isRed;
        boolean isBalloon;

        isRed = scnr.nextBoolean();
        isBalloon = scnr.nextBoolean();

        if(isBalloon && isRed){
            System.out.println("Red balloon");
        }
        else if(isBalloon){
            System.out.println("Balloon");
        }
        else {
            System.out.println("Not a balloon");
        }
    }
