Try without catch.. ?

Many people believe that if they use try block then they are obligated to continue with catch block, catch some Exception and do something with it

It is not quite right opinion

You can use try block with following finally block without catch, like this:

try {
int i = 10;
//....
// do smth. here
} finally {
int i = -10
//....
// finalize smth here
}

avoiding catch block. Maybe you do need it at all, you simply do not mind about it. It is a fact that many programmers have no code in catch block So, why bother about it all. If you do not have a strategy for error handling do not do it all! Just continue.

Someone still may ask: so why we need try if we do not catch? Is not it simpler to run just plain code without any blocks. Please do not forget that we use try to try something, if it does not go we can continue anyway. Plain code just will stop and cause runtime error, which will break your program flow.
