Question

in Java using netbeans

create a project and in it a class with a main.

We will be using the Scanner class to read from the user. At the top of your main class, after the package statement, paste

import java.util.Scanner;

Part A

☑ In your main method, paste this code.

         Scanner scan = new Scanner(System.in);
        System.out.println("What is x?");
        int x = scan.nextInt();
        System.out.println("What is y?");
        int y = scan.nextInt();
        System.out.println("What is z?");
        int z = scan.nextInt();
        System.out.println("What is w?");
        int w = scan.nextInt();
        
        boolean happy;
        boolean dead;
        
        System.out.println("Are you happy (y/n)?");
        String userhappy = scan.next();

        System.out.println("Are you dead (y/n)?");
        String userdead = scan.next();

☑ After this, if what they enter for userhappy is "y" set happy to true, otherwise to false.

Do the same again to set a value for dead, so that we can better serve our zombie users.

☑ Write single if statements using boolean operators to do as follows:

• if x, y, and z all have the same value and the user is happy then print "Same and happy"
• if w is over 12 and the user is both happy and alive then print "Over 12, happy, alive"
• [EC+10] if x is less than z and both w and y are in the range between x and z, and either the user is happy and dead, or sad and alive then print "Long expression is . . . long"

Java class :

//import package
import java.util.Scanner;

//Java class
public class XYCLass {
   // main() method
   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       System.out.println("What is x?");
       int x = scan.nextInt();
       System.out.println("What is y?");
       int y = scan.nextInt();
       System.out.println("What is z?");
       int z = scan.nextInt();
       System.out.println("What is w?");
       int w = scan.nextInt();

       boolean happy;
       boolean dead;

       System.out.println("Are you happy (y/n)?");
       String userhappy = scan.next();

       System.out.println("Are you dead (y/n)?");
       String userdead = scan.next();
       // checking value of userhappy
       if (userhappy.toLowerCase().contentEquals("y")) {
           // if userhappy is y then set happy=true
           happy = true;
       } else {
           happy = false;
       }
       // checking value of userdead
       if (userdead.toLowerCase().contentEquals("y")) {
           // if userdead is y then set dead=true
           dead = true;
       } else {
           dead = false;
       }
       // checking value of x , y and z
       if (x == y && y == z && z == x && happy == true) {
           // if x, y, and z all have the same value and the user is happy
           System.out.println("Same and happy");
       } else if (w > 12 && happy == true && dead == false) {
           // if w is over 12 and the user is both happy and alive then print "Over 12,
           // happy, alive"
           System.out.println("Over 12, happy, alive");
       } else if (x < z && (w > x && w < z) && (y > x && y < z) && (happy == true && dead == true)
               || (happy == false && dead == false)) {
           // if x is less than z and both w and y are in the range between x and z, and
           // either the user is happy and dead, or sad and alive then print "Long
           // expression is . . . long"
           System.out.println("Long expression is . . . long");

       }

   }

}
