Exception Handling

What is Exception Handling?

The Exception is when an event occurs during the execution of a program that disturbs the flow of the program and stops the execution of the program. Exception handling is the mechanism to handle this runtime exception. In Exception handling, the developer writes code to catch the error from code and show it when it occurs, which maintains the normal flow of the program. In java, a built-in class defines a structure of Exception, and we can make our user-defined exception handling class handle such errors.

Advantages of Exception Handling

  • Easy to detect exceptions : You can use try and catch block to identify the code that generates exceptions in java.
  • Meaningful reporting of exception: After detecting the runtime exception, the exception handling mechanism maintains the normal execution flow and shows the Exception in a meaningful way.
  • Detects types of exception: The exception handling mechanism also detects the types of Exceptions, which helps solve them faster.

Scope Of Exception Handling

Exception handling is used in the Java language, where a built-in class ‘Exception’ provides the structure to make our user-defined exceptions. Exception handling mechanisms maintain the flow, which leads to the normal execution flow of programs and shows the exceptions with their types. To learn to implement this mechanism, you need to learn the Java language, which helps you understand exception handling mechanisms. Various platforms allow you to learn java online.
