How to catch ALL Exception in ONE TIME

Question

I'm explain my issue:
I'm making a program with Class, Swing, Thread ...
Then all action I do on my graphical application, I use a new thread, well
I want to capture in my Startup programs, all unknow exception and then, I display it with a JOptionPane for example
In fact, I want to do something like Eclipse, when it crash, I capture the error
Could you help me ? Tell me the best way to do that ?
This is an exemple
FILE: Startup.java
class Startup{
public static main (String args[]){
try{
new Main();
}catch(Throwable e){
//Message d'erreur fenetre
FILE: Main.java
class Main{
Main(){
init_action();
void init_action(){
mybutton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
Thread th=new Thread(){
public void run(){
int a = 1 / 0;
th.start();
Well, in this example I want to capture the Divide By 0, I use the Throwable Exeption, in order to be sure I catch all unknow exeption
Then, a good job, is to put throws Throwable in all function
but Thread, and ActionPerformed ... could not implement it
How to put this exception and jump it to Startup Program ?

Answer 1

I already do that, what can I do for improving capture ?
That's impossible ... It will be a great idea to make a Redirection of Error to a Exception class in futur version
For example, when an unknow error arrive, don't show it on console and crash ... but run a class redirector exception, and magic, it show you a beautiful error warning, and stop properly the programme ...
I put an error class, and put try {] catch {} everywhere, and run my exception class,
this class detect the error exception and run a properly beautiful and clear french message (I'm french :d)
Well, If you have the BEST other idea, tell me, I read your message with a lot of regard
see you soon
bye
