Programming :: Breaking Out Of Nested Switch Java

I've only gone into the first case statement of the first switch and I am trying to get out of it but the break statement I added doesn't seem to have any effect and it just goes on to the next case instead of exiting the switch.

Code:
import java.util.*;
import javax.swing.*;
public class A2 {
public static void main(String[] args) {
double gross_Pay;
int payment_Method;
final double salary_Pay = 1000.00;
final double hourly_Pay = 25.00;
double overtime1 = 20.00;
double overtime2 = 30.00; .....
