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"

Scanner scan = new Scanner(System.in);//starter code provided

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();
  
if(userhappy.equals("y"))//check if userhappy is y or not
happy=true;
else
happy=false;
  
if(userdead.equals("y"))//check if userdead is y or not
dead=true;
else
dead=false;
  
if(x==y && y==z && happy )//check the conditions and print appropriate messages on console
System.out.println("Same and happy");
  
if(w>12 && happy && !(dead))
System.out.println("Over 12, happy, alive");
  
if(x<z){
if(w>x && w<z){
if(y>x && y<z){
if((happy && dead) || (!happy && !dead))
System.out.println("Long expression is . . . long");
  
}
