how do I get back to an outer switch if I am inside an inner switch?

Question

I am trying to program a menu for my calculator. I do not know how to get out of my inner loop and get back to my outer loop once I have executed the inner loop. I have to finish the whole case of the inner loop before I can get back to the outer loop. Is there a way that I can go back and forth of the nested switch whenever I want to? and when I execute my outer switch case 3, it executes infinitely. Maybe because it's inside a loop.

import java.util.Scanner;

public class MainInterface {
    static Scanner input = new Scanner(System.in);
    
    static boolean hasRun = false;
     public static void main(String args[])

         Calculator Mycal = new SimpleCalculator();
         ScientificCalculator Mycal2 = new ScientificCalculator();
         
         mainMenu();
         int choice = input.nextInt();
         
         do {
         
         System.out.println("\n");
        
         switch(choice) // outer switch
         {
         case 1: simpleCalculatorMenu();
                
                int choice2 = input.nextInt();
                
                    switch(choice2)  // inner switch

Answer 1

by adding label you can try like this

        OUTER:
        switch(condition1) {
            case x:
                switch(condition2) {
                    case y:
                        System.out.println("hello");
                        break OUTER;
                }
        }
