Java - How to Write blank exception handlers

I know it's very tempting to write blank exception handlers, and to just ignore errors. But if you run into problems, and haven't written any error messages, it becomes almost impossible to find out the cause of the error. Even the simplest exception handler can be of benefit. For example, put a try { .. } catch Exception around your code, to catch ANY type of exception, and print out the message. You don't need to write a custom handler for every exception (though this is still good programming practice). Don't ever leave it blank, or you won't know what's happening.

For example

public static void main(String args[])
{
    try {
 // Your code goes here..
    }
    catch (Exception e)
    {
 System.out.println ("Err - " + e );
    }
}
