Handle all unhandled exceptions

Is it possible to handle (a simple log entry) all unhandled exceptions?

In more detail, I need to register any exception that occurs anywhere in the code, register an exception and then continue (which can lead to more significant exceptions!).

You can use the Default Uncaught Exception Handler to catch any inexhaustible exceptions.

You can also set a specific handler for a stream or group of threads.

here is a piece of code that could help you:

public class MyDefaultExceptionHandler extends DefaultExceptionHandler
  {

  private UncaughtExceptionHandler defaultUEH;

  public MyDefaultExceptionHandler() 
    {
    this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler();
    }

  @Override
  public void uncaughtException(Thread t, Throwable e) 
    {
    //print anything you wish about the Throwable e :getStackTrace(), getCause(), getClass()...
    defaultUEH.uncaughtException(t, e); //this will call the default handling of the exception (crash...)
    }
  }
… 
//in the main app:
Thread.setDefaultUncaughtExceptionHandler(new MyDefaultExceptionHandler());
