Convoluted way to demonstrate assignment operators in Java

AssignmentOperators.java

import java.util.Scanner;


public class AssignmentOperators {
  public static void main(String args[]) {
		int k = 5;
		double d;
		Scanner myScanner = new Scanner(System.in);
		
		System.out.println("select the assignment operator you want to use: \n" + "1. addition\n" + "2. substraction\n" + "3. multiplication \n" + "4. division \n");
		int x = myScanner.nextInt();
		System.out.print("You selected: ");
		if (x == 1) {
			System.out.println("addition");
			//int k = 5;
			System.out.println ("original value of k = " + k);
			k += 4;
			System.out.println("value of k after increment assignment operator = " + k);
		}
		else if (x == 2) {
			System.out.println("subscrtation");
			System.out.println ("original value of k = " + k);
			k -=4;
			System.out.println("value of k after subsctration assignment operator = " + k);
			
		}
		else if (x==3) {
			System.out.println("multiplication");
			System.out.println("original vlaue of k = " + k);
			k *= 2;
			System.out.println("value of k after multiplication assignment operator = " + k);
		}
		else if (x == 4) {
			System.out.println("division");
			System.out.println("original value of k = " + k);
			d = k;
			d /=2;
			System.out.println("value of k after division assignment operator = " + d);
		}
		else {
			System.out.println("invalid choice");
		}
