4. try/catch/finally rules

• Statements that might generate an exception are placed in a try block

• Not all statements in the try block will execute; the execution is interrupted if an exception occurs

• The try block is followed by

  • one or more catch blocks

  • or, if a try block has no catch block, then it must have the finally block

• A catch block specifies the type of exception it can catch. It contains the code known as exception handler

• The last catch block may be followed by an optional finally block

• Any code contained in a finally block always executes, regardless of whether an exception occurs, except when the program exits early from a try block by calling the System.exit() method
