create a calculator in java using switch statement | IntelliJ idea IDE | java project for beginners

Hello guys?, welcome to my channel. In this video, I discuss a java project for beginners, how we create a calculator in java using a switch case statement in IntelliJ idea ide.
This is a basic calculator which is able to add, subtract, multiplication and division two numbers.
Here is a copy of the code :



import java.util.Scanner;

public class Calculator {
public static void main(String[] args) {
int num1, num2;
String operator;
int result = 0;
Scanner sc = new Scanner(System.in);
System.out.println("Enter the operator : ");
operator = sc.next();
System.out.println("Please enter the first number : ");
num1 = sc.nextInt();
System.out.println("Please enter the secound number : ");
num2 = sc.nextInt();
sc.close();

switch (operator) {
case "+":
result = num1 + num2;
break;

case "-":
result = num1 - num2;
break;

case "*":
result = num1 * num2;
break;

case "/":
result = num1 / num2;
break;
default:
System.out.println("Error ! please enter a valid input");
break;
}
System.out.println("The result is : " + result);
}
}
