What are checked and unchecked exceptions in Java? Give examples of each
In Java, exceptions are categorized into checked and unchecked. Checked exceptions are those that the compiler checks at compile-time. Developers must handle them using try-catch blocks or declare them using the throws keyword. Examples include IOException and SQLException. Unchecked exceptions are not checked at compile-time; they occur during runtime and are usually due to programming errors. Common examples include NullPointerException and ArrayIndexOutOfBoundsException. Proper understanding of both types is essential for writing robust Java programs. Mastering exception handling is a vital part of any Java certification course.
