I am currently building a client program to receive broadcasted message by the server. Just want to make things clear, is it correct that the method startRunning() will keep looping itself without anyone calling it? Also, the incoming data is in the form of bytes, can i use the method .read(message) to read and store the data into message[]?

Is it correct that the method startRunning() will keep looping itself without anyone calling it?
You have to call the method startRunning() at least once so that it starts executing its code; after that the while block will continue to loop infinitly unless an exception occurs.
Also, the incoming data is in the form of bytes, can i use the method .read(message) to read and store the data into message[]?
Yes, you can. See this link for the specifications
If I might add a tip:
private boolean Continue = true;
public void setContinue(boolean b)
{
Continue = b;
}
public void startRunning() throws IOException
{
DataInputStream in;
try
{
while (Continue)
{
System.out.println("receive");
InputStream inFromServer = myClient.getInputStream();
in = new DataInputStream(inFromServer);
in.read(message);
System.out.println(Arrays.toString(message));
}
}
catch (EOFException eofexception)
{
System.out.println("error");
}
catch(Exception ex)
{
in.close();
throw ex;
}
}
Note the condition of the while-loop. This would make your code more responsive to interrupts, should you need them; streams should not be open infinitly.
Also, you ought to close the stream when an exception does occur.

After exporting project to jar file, my project is not fully working

i have a problem that in Eclipse when i run my project everything is working fine but when i exporting it last class don't want to open by clicking the button. I'm using database in every class as well as i have referenced library(jcalendar-1.4) if it will help you to solve the problem.
login and registration class are working fine and after logged in and transfer to addActivity class most thing are working like adding everything to database but that one button is unable to open that last class that should show all activities added.

Check on the basis of button text
((JButton)source).getText().equals("Add Book")
here is complete code
public void actionPerformed(ActionEvent e) {
Object source = e.getSource();
if (source instanceof JButton && ((JButton) source).getText().equals("Add Book")) {
...
}
}

This worked for me. I had to match the String as the e.getsource was not working.
public void actionPerformed(ActionEvent e) {

String test = ((JButton)source).getText();
if(test == "Add Book"){

Inheriting from a JFrame class to another class and using the variables

I'm new in java, and I'm working on a program using GUI. My problem is that I'm reaching 1000 Line and this is stressful because all my code are in one file. I'm not liking this. So I research the internet about Inheritance. However, I'm not sure how this can help me in my problem because all what I know about Inheritance that Inherit everything in the parent class. However, when I try to use a variables in the child class I can't for example let say that I have in the parent class something like this:
JButton getButton = new JButton("Enter");
now when I go to the child class. I want to Inherit and use this variable so I can use the ActionListener it's not working.
So could any tell me what I'm I doing wrong here, or this not the right way to do it ?
Thank you everyone before and after.
Here is some of my code:
public class H_Store extends JFrame {

public void run() {
try {
H_Store frame = new H_Store();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**

What I want to do exactly is to take the last code into another class or do something with so I can use it in the Parent class, in other word any math I want outside the Parent class.
Note: I mean this code
private class CalcButtonListener implements ActionListener{

private double total_GM;
private double weightPrice_1;
private String stringQ;
private String stringW;
private String stringP;
private int meat_Q1;
private double meat_W1;
private double meat_P1;
public void actionPerformed(ActionEvent e){
total_GM = 0;
// The ground Meat check box calculation
stringQ = ground_M_QTextField.getText();
meat_Q1 = Integer.parseInt(stringQ);
stringW = ground_M_WTextField.getText();
meat_W1 = Double.parseDouble(stringW);
stringP = ground_M_PTextField.getText();
meat_P1 = Double.parseDouble(stringP);
weightPrice_1 = meat_W1 * meat_P1;
total_GM += weightPrice_1 * meat_Q1;
JOptionPane.showMessageDialog(null, total_GM + "\n" + s);
}
}

You state:
My problem is that I'm reaching 1000 Line and this is stressful because all my code are in one file. I'm not liking this.
You are quite right to not like this and to try to improve this set up as this type of program will be a monster to maintain, debug and enhance..
You then state:
Inheriting from a JFrame class to another class and using the variables
This is not what inheritance is for as objects of the child class will be a completely distinct entities from objects of the parent class, so you will not want to do this.
Instead
Remember to strive to enhance by composition rather than inheritance, meaning have classes contain fields of other classes.
Avoid using the static modifier to make global-like variables as this will hog-tie your code.
try to break out logical parts of your program from the visual, the GUI parts,
And split up each specific logical part and each major GUI part into its own class.
make sure all classes have decent setter and getter methods,
and that the classes are written so that they communicate well with each other.
A Swing specific recommendation is for you to avoid extending JFrame.
Instead gear your Swing GUI's towards creating JPanels, panels which can be placed anywhere you want them, including in JFrames, JApplets, JDialogs, JOptionPanes, inside of other JPanels, in JTabbedPanes, as "cards" in a CardLayout-using JPanel,....
This will greatly improve the flexibility and enhance-ability of your program.
For more specific help, please feel free to provide more details about your program and its code.
Edit
Sorry to be blunt, but you've come for advice on your code, and I have to inform you that it has some significant problems including:
it contains more quite a bit of unnecessary redundency that makes it hard to follow and debug.
You have grids of JTextFields, all of which can and should be replaced by three JTables, one for Meat, one for Chicken, and one for "other things".
You use null layouts and absolute positioning, something that seems to a newbie an easier way to create complex GUI's, but in the long run is the most difficult way to create, maintain and upgrade these. You're far better off learning about and using the layout managers, including nesting JPanels each with its own layout.
Any time I see variables named something12, something13, something14, something15, something16, something17, something18, ... I think that most of this can be replaced by an array or a collection such as an ArrayList, or in your case (as noted above), a JTable whose model is based in a collection.
Each one of your table entries should likely be in its own class.
I stand by my original recommendation that you should not have any of your classes inherit from the main GUI as this will lead to non-workable code.
Also, your JFrame should not launch another JFrame, but rather the getProfitButton should launch a modal JDialog.

First of all try to divide your code into methods, that would make your code more clear.
As for inheritance, you can only modify variables that are in the parent class from the child class if those variable are :
.Data members
.Their visibility is set to protected
Here is an example
public class Parent{
protected JButton button;
protected int something;
protected String whatever;
//^Those are the data members
public Parent(){//Constructor
//some code here
}
//more code
}//end of parent class
public class Child extends Parent{
private int randomstuff;
private String morerandomDatamembers;
public Child(){
super();
}
public void modify(){
something=3;
whatever="yayyy it worked";
}
}
protected data members can only be accessed by the children of some class.
EDIT- Inheritance can be used in specific cases. You can still modify data members of some class from a different class. Every method should have getters and setters.
Example:
public class Car{
private int ModelNumber;
private String CarName;
public Car(int ModelNum,String name){
ModelNumber=ModelNum;
CarName=name;
}
public int getModelNum(){//First getter
return ModelNumber;
}
public void setModelNum(int ModelNum){//First setter
ModelNumber=ModelNum;
}
public String getCarName(){//Second getter;
return CarName;
}
public void setCarName(String Car){
CarName=Car;
}
}
public class Company{
private Car car;
public Company(Car c){
car=c;
}
public void modify(){
car.setModelNum(123);
car.setCarName("Ferrari");
System.out.println("Being so awesome,Roudy will let me try his Ferrari");
}
}
