Throw-and-Throws

In Java, exception handling is a crucial aspect of writing robust and error-free code. Two key keywords in this context are “throw” and “throws.” The “throw” keyword is used to explicitly throw an exception from a method or a block of code, allowing developers to signal that an error has occurred. In contrast, the “throws” keyword is part of a method’s signature, indicating that the method may throw certain exceptions during its execution. Understanding the differences between these two keywords is essential for effective exception management and ensuring that your code can handle errors gracefully.
