Frequently Asked Questions

What is Exception Handling?

Exceptions are unwanted bugs or events that break the normal flow of the program. Exception handling is the process that ensures the flow of the program even when exceptions occur. When a program has a bunch of statements, and an exception occurs while running the program after executing a few statements, the statements after that exception will not be executed, and the program terminates. Reasons why exceptions occur include:

  • The user providing invalid data 

  • The requested file to access is not located in the device 

  • Java Virtual Machine (JVM) is running out of memory

  • Networking dropping while the communication is ongoing

Why do we need Exception Handling?

Exception handling ensures the flow of the program even when exceptions occur. An exception disrupts the program's flow, which is the core reason why handling them is essential. It maintains the desired flow of the applications when unexpected events occur. If not handled properly, programs may fail or crash. This would be a hitting point to your customers when this happens repeatedly, and you might even lose them in a while. So it is apt to leverage this feature and implement it in all the programs.

What are the types of Exception Handling in Java?

Java handles exceptions in two ways. They are:

  • Checked Exception: These are compile-time exceptions since they are crawled by the compiler during compilation to confirm if the programmer handles the exception. If the exception is not handled, then the system throws up compilation errors. Examples: SQLException, InvocationTargetException, IOException, ClassNotFoundException.

  • Unchecked Exceptions: Unchecked exceptions occur during the program's execution and are hence called runtime exceptions. These are ignored during compilation. Examples: Using incorrect APIs and programming bugs such as logical errors.
