        The folloring example defines a variable x within a try/catch block and 
        then tries to access it outside of the block, which results in an undefined 
        variable error!
        

        try
        {
		    long x = 5;
		    x = x * 10;   // ok
        }
        catch ( Exception e ) {}

	    x = x + 9;   // error! undefined variable!


        
        The variable x is only valid within the try/catch block. To fix, do this:
        

        long x = 5;

        try
        {
            x = x * 10;   // ok
        }
        catch ( Exception e ) {}

        x = x + 9;   // ok
