Exceptions in Java

# Exceptions in Java Exceptions are events that occur during the execution of a program, which disrupt the normal flow of the program's instructions. In Java, an exception is an object that wraps an error event that occurred within a method and contains: the error message, the name of the class where the error occurred, and the call stack. When an exception is thrown, the current normal flow of the program is interrupted and the corresponding exception handler is executed. Java provides a robust and object-oriented way to handle exceptions. By using the built-in Exception class, you can create custom exceptions that are tailored to your application's needs. You can also group related exceptions into a single class and throw exceptions that are more meaningful and easier to debug. Additionally, Java provides several built-in exceptions that you can use in your applications. In Java, exceptions are divided into two categories: checked and unchecked. Checked exceptions are checked at compile time and must be handled, while unchecked exceptions are not checked at compile time and can be either handled or ignored. Java also provides a try-catch block, which allows you to handle exceptions in a structured manner. The try block contains the code that might throw an exception, while the catch block contains the code to be executed when an exception is thrown. This allows you to catch exceptions and handle them gracefully, as opposed to abruptly crashing the program. In conclusion, Java provides a robust and object-oriented way to handle exceptions.

Exceptions in Java are objects that are thrown when something unexpected occurs during the execution of a program. They are used to inform the programmer of an error and can be handled in order to prevent the program from crashing. An exception can be handled using a try-catch block. This is a structure that allows a program to test for errors and take action if an error occurs. ### Sample Code ```java try { // Code that may throw an exception } catch (Exception e) { // Handle the exception } ```
