What have you tried? Where exactly are you stuck? What exactly are you confused about?

Dude as I Above Shown my code was for a simple hotel management
I Have 4 diff Items and different prices and atlast I Want to add the Price of that all items.

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
/*
<APPLET CODE="hotel1" HEIGHT =300 WIDTH=500 >
</APPLET>
*/
public class hotel1 extends Applet implements ActionListener
{
Button b2,b3,b4,b5;
TextField tf1;
Color clr;
Label l1,l2,l3;
public hotel1()
{

clr=new Color(219,240,251);
setBackground(clr);
setLayout(null);
tf1=new TextField(5);
l1=new Label("Enter Quanity");
l1.setBounds(5,10,130,30);
l2=new Label();
l2.setBounds(5,10,130,30);
l3=new Label("Amount");
l3.setBounds(100,70,180,30);
tf1.setBounds(150,10,130,20);


b2=new Button("Dosa");
b2.setBounds(80,180,70,35);
b3=new Button("Idly");
b3.setBounds(20,130,80,30);
b4=new Button("Vada");
b4.setBounds(110,130,80,30);
b5=new Button("Poori");
b5.setBounds(200,130,80,30);



add(l1);
add(tf1);
add(b2);
add(b3);
add(b4);
add(b5);

add(l2);
add(l3);
l2.setFont(new Font("",Font.BOLD,14));
l2.setForeground(Color.RED);

b2.addActionListener(this);
b3.addActionListener(this);
b4.addActionListener(this);
b5.addActionListener(this);
}


public void actionPerformed(ActionEvent ae)
{


float A=0;

int a = Integer.parseInt(tf1.getText());
if(ae.getSource()==b2)
{
A(30*a*14) / 100)+(30*a));
System.out.println("Dosa"+"*"+a+" = "+(A));//Buton 1
}
if(ae.getSource()==b3)
{
A(20*a*14) / 100)+(30*a));
System.out.println("Idly"+"*"+a+" = "+(A));//Button 2

}
if(ae.getSource()==b4)
{
A(20*a*14) / 100)+(30*a));
System.out.println("Vada"+"*"+a+" = "+(A));//Button 3
}
if(ae.getSource()==b5)
{
A(30*a*14) / 100)+(30*a));
System.out.println("Poori"+"*"+a+" = "+(A));//Button4
}



l3.setText(String.valueOf(A));


}


public static void main(String[] args)
{
new hotel1();
}



}

this was my Complete code

Hmm due i donno nothing about Highlighting the code and formatting I'm New in this field
I Just want to know logic to add A1,A2,A3,A4.

				//I Want to add All this Buttons Please tell me which logic to be implemented
				l3.setText(String.valueOf(A));

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).

Dude I Cannot able to understand Y u r not getting me No I'm Not Asking How to add buttons to Window
Iam Asking How to add that Button Values for example my first button value is 30 and 2nd button value is 40
Now I Want logic to add this bothe values and I Should get value 70

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);
				}

already i Tried total = A1+A2+A3+A4; but its not working I'm Getting value of Total==0
Please Advice me any other Logic

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));
