Thread: Need help on how to add numbers to jlabel

So Basically I am creating this pizza program and on one page I have a section where people can choose a list of toppings. Now each topping is 1.50 and as soon as they click a topping a sidebar on my gui would display the price. Now I have 12 toppings radio buttons but the problem arises when I click 2 radio buttons it just displays the price 1.50.

I just want to know if there's a way to add 1.50 to my jLabel on my sidebar every time I press a topping button and when I deselect a topping it would subtract 1.50 from the jLabel so the price is accurate.

Here is my code I have done til now

 
Pepperoni Radio Button
 
final String LastMoney = ToppingsPriceL.getText(); 
final double LM = Double.parseDouble (ToppingsPriceL.getText()); 
 
String PBtn = PepperoniBtn.getText(); 
 
boolean PepperoniBtn; 
PepperoniBtn = true;
 
 if (PepperoniBtn) { ToppingsDisplayL.setText(PBtn); 
 
ToppingsPriceL.setText(Money.format(1.50 + LM)); }
 }
 
 
 
Green Olive Radio Button
 
 
final String LastMoney = ToppingsPriceL.getText(); 
final double LM = Double.parseDouble (ToppingsPriceL.getText()); 
 
String GObtn = GreenOlivesBtn.getText();
 boolean GreenOlivesBtn;
 
 GreenOlivesBtn=true;
 
 if (GreenOlivesBtn) { 
 
ToppingsDisplayL.setText(GObtn); ToppingsPriceL.setText(Money.format(1.50 + LM)); }
