Can I use try/catch block to control program flow? Will it affect program perfor

Go to all tips in General Java

Question: Can I use try/catch block to control program flow? Will it affect program performance?

Answer: Try/catch block itself does not add much overhead to your program. Handling of thrown exception can be expensive.
Use try/catch block only for error handling, not to control program flow. Especially try to avoid placing within loops.

Go to all tips in General Java

Question: I have a method that names something like this - public String doSmth()...
I do not need any Object for this method. Can I make it static?
Is it good idea to make all methods that do not use Objects static?

Answer: yes, I think so. It is bad idea to create an instance of the class just to use one method without needing the instance
itself. Wasting of memory and CPU performance for further garbage collecting of the Object that has not been used Smile
