Question

JAVA Codelab (20940): [Sequential and Nested if/else Statements] Given a int variable named yesCount and another int variable named noCount and an int variable named response write the necessary code to read a value into into response and then carry out the following: if the value typed in is a 1 or a 2 then increment yesCount and print out "YES WAS RECORDED" if the value typed in is a 3 or an 4 then increment noCount and print out "NO WAS RECORDED" If the input is invalid just print the message "INVALID" and do nothing else. ASSUME the availability of a variable, stdin, that references a Scanner object associated with standard input.

Answer 1

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new java program with name "Main.java" is created, which contains following code.

Main.java :

import java.util.*;//import package
public class Main //Java class
{
//entry point of program , main method
   public static void main(String[] args) {
   //creating object of Scanner class
   Scanner sc=new Scanner(System.in);
   //declaring variables
   int yesCount=0,noCount=0;
   //asking user to enter value
       System.out.print("Enter response : ");
       int response=sc.nextInt();//reading response
       //checking response
       if(response==1 || response==2)
       {
       //if response is 1 or 2 then
       yesCount++;//increment yesCount
       System.out.println("YES WAS RECORDED");//print
       }
       else if(response==3 || response==4)
       {
       //if response is 3 or 4 then
       noCount++;// increment noCount
       System.out.println("NO WAS RECORDED");//print
       }
       else
       {
       //for any other value print
       System.out.println("INVALID");
       }
   }
}

======================================================

Output : Compile and Run Main.java to get the screen as shown below

Screen 1 :Main.java ,when 1 or 2 is entered

Screen 2 :Main.java ,when 3 or 4 is entered

Screen 3 :Main.java ,when invalid response is entered
