Understanding Java Exceptions
An exception is a situation that arises during the execution of an application, disrupting its normal flow. Java classifies exceptions into two types: checked and unchecked. Understanding these types of exceptions is essential for implementing effective strategies to handle them.
Checked exceptions: These are exceptions that must either be caught or declared within the method in which they may occur. These exceptions extend but exclude runtimeException. The compiler checks for checked exceptions at compile time, requiring handlers to deal with these exceptions.
Unchecked Errors These include runtime errors and exceptions. They extend Java. lang.RuntimeException and java. lang.Error respectively. Unchecked errors are not checked during compilation, so the compiler doesn't require them to be declared or caught. Runtime exceptions can be used to signal programming errors such as logic mistakes or improper usage of an API. Java Classes in Pune | With 100% Placement (2024)
