    Again, when posting code, please use the highlight tags to preserve formatting. The code you've posted is pretty much unreadable.

    And the reason I'm asking what you're confused about is you've told us your requirement, but not what's preventing you from achieving that requirement. What are you confused about?

    Please do not post multiple copies of the same question. I've deleted your duplicate post.

    You aren't making it easy for us to help you- I'm still not sure exactly what you're asking, and you haven't posted an SSCCE or an MCVE demonstrating where you're stuck. You've told us you need to add all of the buttons, but you haven't specified what's stopping you from doing so. Are you asking how to add integer values? How to add buttons to a window? Something else?

    I recommend reading the link in my signature on asking questions the smart way and posting a more specific question (in this thread, not in a new post).

    Default Re: How to Add all the Button Values

    Okay, and what have you tried?

    What is a button's value? Are you talking about the text displayed on the button? Its label? Some other associated value? I am "unable to understand Y u r not getting me" because you haven't asked a specific technical question. "Adding buttons" could mean any number of things.

    Again, I recommend you read the link in my signature on asking questions the smart way before you post again.

    Default Re: How to Add all the Button Values

    I might be missing something here, but what value does "a" have?

    --- Update ---

    Oh nvm, I just saw it *facepalm*

    The way you have it, it doesn't look like you can add it

    Unless... Con you read one action at a time and have that stored in a variable and then add both variables? Will a be different when you add the button values?

    Also, what is this "+(A))" thing about?

    Hope that makes sense

    Default I Want to add A1,A2,A3,A4 values

    Let us Suppose I get Values for A=10= A2=30 A3=40=A4=50 and I wanna get Output as Total = 10+30+40+50==130
    Please Suggest me Code for this to happen
    In this Logic a=No Of Quantity


    		public void actionPerformed(ActionEvent ae)
    		{
     
     
    				float A=0,A1=0,A2=0,A3=0,A4=0,Totall=0;
     
    				int a = Integer.parseInt(tf1.getText());
    				if(ae.getSource()==b2) 
    				{
    					A1=(((30*a*14) / 100)+(30*a));
    					System.out.println("Dosa"+"*"+a+" = "+(A1));//Buton 1 
    				}
    				if(ae.getSource()==b3) 
    				{
    					A2=(((20*a*14) / 100)+(30*a));
    					System.out.println("Idly"+"*"+a+" = "+(A2));//Button 2 
     
    				}
    				if(ae.getSource()==b4) 
    				{
    					A3=(((20*a*14) / 100)+(30*a));
    					System.out.println("Vada"+"*"+a+" = "+(A3));//Button 3 
    				}
    				if(ae.getSource()==b5) 
    				{
    					A4=(((30*a*14) / 100)+(30*a));
    					System.out.println("Poori"+"*"+a+" = "+(A4));//Button4 
    				}
    				if(ae.getSource()==b1&&ae.getSource()==b2||ae.getSource()==b3||ae.getSource()==b4||ae.getSource()==b5)
    				{
    					Totall=A1+A2+A3+A4;
    					System.out.println("Total="+Totall);
    				}

    Like I said, please don't post multiple copies of the same question. I've merged your threads.

    I still don't understand what you're asking. If you have values A1 through A10 and you want to set the value of total to their sum, you simply do this:

    double total = A1+A2+A3+A4+A5+A6+A7+A8+A9+A10;

    If that's not what you're asking, you have to be more specific. It would be better if you posted an SSCCE or MCVE.

    Default Re: How to Add all the Button Values

    Like I said, it's pretty hard to help you without a small example. In this case, it can just be a main method that contains your 4 A variables hardcoded to a certain value, as well as the total variable and a print statement. Here, I'll start:

    public class Test{
       public static void main(String... args){
          float a1 = 10;
          float a2 = 20;
          float a3 = 30;
          float a4 = 40;
     
          float total = a1+a2+a3+a4;
          System.out.println(total);
       }
    }

    Modify that program so it reflects the problem you're having.

    I Cannot Initialize the Values I Should Get Value Depending on the value of SMALL a and based on the Logic (((30*a*14) / 100)+(30*a));

    Then put that logic into the program I posted. The idea is to show us exactly what your code is doing, without all of the extra GUI code.
