    Default 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)); }

    when I click 2 radio buttons it just displays the price 1.50
    What should be displayed?

    a way to add 1.50 to my jLabel
    Is the JLabel supposed to display a total amount? Should each new order increment the amount shown?

    The posted code needs formatting to help make it readable. Logically nested statements should be indented.
    Statements should not all start in the first column.

    Also there isn't enough code shown to know what is happening.
    If you don't understand my answer, don't ignore it, ask a question.
