The try statement allows you to define a block of code to be tested for errors while it is being executed. But finally is useful for more than just exception handling - it allows the programmer to avoid having cleanup code accidentally bypassed by a return, continue, or break. This ensures that the finally block is executed even if an unexpected exception occurs. The finally block always executes when the try block exits. It is not mandatory to include a finally block at all, but if you do, it will run regardless of whether an exception was thrown and handled by the try and catch parts of the block. Java finally block is always executed whether exception is handled or not. A finally contains all the crucial statements regardless of the exception occurs or not. The finally block executes whether exception rise or not and whether exception handled or not. closing the file or closing the connection. The finally block in java is used to put important codes such as clean up code e.g. One case where it is common practice to throw a RuntimeException is when the user calls a method incorrectly. Thus, the compiler does not require that you catch or specify runtime exceptions (although you can). Runtime exceptions can occur anywhere in a program, and in a typical one they can be very numerous. When you detect an error with the way your class or method is used, throw a runtime exception. Runtime exception serve a specific purpose – they signal programming problems that can be fixed only by changing code, as opposed to changing the environment in which the program runs. Thus the compiler does not require that you catch or specify runtime exceptions, although you can. Typically, the cost of checking for runtime exceptions exceeds the benefit of catching or specifying them.
