Large effect of Try Catch

Think that try catch is the Eclipse compiler automatic reminder add, if not added, Eclipse write program will error, and will remind you to add. Programmers don't have to worry about the problem. That's all.

But he has a more important role to play.

Therefore, with a try catch, the program does not report errors such as NULL null pointers, and causes the program to get stuck without continuing to execute the following program.

In particular, there are interface calls to the program, if the interface is not through, will be error, and once the error, the code behind me will not be executed.

Add a try catch will error, will not affect my business functions, even if the interface is not access, my program will continue to go down, without error.

It's just an unusual report.

Exceptions do not affect the program to continue, but the error will be.

This is the biggest difference between error and exception.
