Exception Handling in Java
Exception handling in Java is a crucial mechanism for managing runtime errors without abruptly terminating a program. It allows programs to continue executing even when an error occurs, enhancing user experience and stability. The try-catch structure is commonly used to handle exceptions, providing a way to manage errors gracefully.
- ▪An exception disrupts the normal execution of a program, such as dividing by zero.
- ▪Without exception handling, a program stops immediately when an error occurs.
- ▪The try-catch structure allows for proper error handling, enabling the program to continue executing.
