                                       In this tutorial i am going to show you how to work with java switch statement along with adding program. to do that follow these steps or simply watch my video.

• First create a notepad file and open it
• Give a name and Save the notepad file with .java (Ex: - decision.java)
• Make sure the save as type is All Files
• Then delete the notepad file if you want and edit the java file with a text editor
• Paste or write down the code (code is below the tutorial) and make sure the class name is equal to the name that given to save the file.
• Save the file and close it
• open CMD (Command Prompt)
• Set the JDK bin folder path coding by %path%;   (Ex:- set path=%path%;C:\Program Files\Java\jdk1.8.0_112\bin) and press enter
• Set the directory where we saved the java file.
• After that need to compile the java file to create class file. simple type - javac filename.java       (Ex:- javac decision.java)
• To run the program type java filename  (Ex:- java decision)

The Code is :-

import java.util.Scanner; //imports scanner to get user input

class decision{ //class name

public static void main(String[] args){ //main method

System.out.println("Do you want to start the application (Type yes or no) :- "); //display this

Scanner begin = new Scanner(System.in); //create a new user input and name it begin

String choise=begin.next(); //declare a variable name choise and getting user input

switch (choise){ //checks choise variable

case "yes": //if choise equal to yes

System.out.println("Welcome to the adding machine"); //display this

break; //end statement

case "no": //if choise equal to no

System.out.println("Exiting"); //display this

System.exit(0); //system exits

break; //end statement

}  

System.out.println("Enter Number 1:- "); //display this

Scanner a = new Scanner(System.in); //create a new user input and name it a

int num1=a.nextInt(); //declare a variable name num1 and get the value of user input

System.out.println("Enter Number 2:- "); //display this

Scanner b = new Scanner(System.in); //create a new user input and name it a

int num2=b.nextInt(); //declare a variable name num1 and get the value of user input

int tot=num1+num2; //declare a variable call tot and assigning value num1 + num2 to tot

System.out.println("Total is: - "+tot);    //display total of num1 and num 2

}
