Never swallow the exception in catch block
Declare the specific checked exceptions that your method can throw
Do not catch the Exception class rather catch specific sub classes
Never catch Throwable class
Always correctly wrap the exceptions in custom exceptions so that stack trace is not lost
Either log the exception or throw it but never do the both
Never throw any exception from finally block
Always catch only those exceptions that you can actually handle
Don't use printStackTrace() statement or similar methods
Use finally blocks instead of catch blocks if you are not going to handle exception
Remember "Throw early catch late" principle
Always clean up after handling the exception
Throw only relevant exception from a method
Never use exceptions for flow control in your program
Validate user input to catch adverse conditions very early in request processing
Always include all information about an exception in single log message
Pass all relevant information to exceptions to make them informative as much as possible
Always terminate the thread which it is interrupted
Use template methods for repeated try-catch
Document all exceptions in your application in javadoc
