1. Don't manage business logic with exceptions. Use conditional statements instead. If a control can be done with if-else statement clearly, don't use exceptions because it reduces readability and performance  (e.g. null control, divide by zero control). .
2. Exception names must be clear and meaningful, stating the causes of exception.
3. Throw exceptions for error conditions while implementing a method. E.g. if you return -1, -2, -3 etc. values instead of FileNotFoundException, that method can not be understand.
4. Catch specific exceptions instead of the top Exception class. This will bring additional performance, readability and more specific exception handling.
5. Null control with conditionals is not an alternative to catching NullPointerException. If a method may return null, control it with if-else statement. If a return may throw NullPointerException, catch it.                     More...
