Calculator menu

This is a function I wrote using the Scanner and Math libraries that allows for the user to choose between multiple mathematical operations.

import java.util.Scanner; // scanner for input, Math for more complex operations
import java.lang.Math;

public class Menu {
   
    public final String DEFAULT = "\u001B[0m";  // Default Terminal Color
  
    // Constructor on this Object takes control of menu events and actions
    public Menu() {
        Scanner sc = new Scanner(System.in);  // using scanner object
        
        this.print();  // print Menu
        boolean quit = false;
        while (!quit) {
            try {  // scan for Input
                int choice = sc.nextInt();  // using method from Java Scanner Object
                System.out.print("" + choice + ": ");
                quit = this.action(choice);  // take action
            } catch (Exception e) {
                sc.nextLine(); // error: clear buffer
                System.out.println(e + "is not a valid input, please try again");
            }
        }
        sc.close();
    }
  
    // Print the menu options to Terminal
    private void print() {
        //System.out.println commands below is used to present a Menu to the user. 
        System.out.println("-------------------------\n");
        System.out.println("Choose a math operation");
        System.out.println("-------------------------\n");
        System.out.println("1 - Add");
        System.out.println("2 - Subtract");
        System.out.println("3 - Multiply");
        System.out.println("4 - Divide");
        System.out.println("5 - Square Root");
        System.out.println("0 - Quit");
        System.out.println("-------------------------\n");
    }
  
    // Private method to perform action and return true if action is to quit/exit
    private boolean action(int selection) {
        boolean quit = false;
  
        switch (selection) {  // Switch or Switch/Case is Control Flow statement and is used to evaluate the user selection
            // i forgot to put curly brackets for each case which is why all the scanner variable names are different
            case 0:  
              System.out.print("Bye!");
              quit = true;
              break;
              
            case 1: //addition
              Scanner add = new Scanner(System.in);

              System.out.println("Enter first number:");
              double firstNumber = add.nextDouble();

              System.out.println("Enter second number: ");
              double secondNumber = add.nextDouble();

              double result = firstNumber + secondNumber;
          
              // Output input by user

-------------------------

Choose a math operation
-------------------------

1 - Add
2 - Subtract
3 - Multiply
4 - Divide
5 - Square Root
0 - Quit
-------------------------

2: Enter first number:
Enter second number: 
0.0 - 1.0 = -1.0

5: Enter a number:
The square root of 2.25 is 1.5

0: Bye!
