In Java, the keywords ‘throw’ and ‘throws’ are used in exception handling, but they have different purposes and usage.

1. ‘throw’ keyword: The ‘throw’ keyword is used to explicitly throw an exception within a method or block of code. It is followed by an instance of an exception class or a subclass of the ‘Throwable’ class. When a ‘throw’ statement is encountered, the normal flow of execution is halted, and the specified exception is thrown. This allows you to create and throw your own exceptions or propagate built-in exceptions to the calling code.
2. ‘throws’ keyword:
   The ‘throws’ keyword is used in the method signature to declare that a particular method might throw one or more types of exceptions. It is used to specify the exceptions that a method can throw, allowing the calling code to handle those exceptions or propagate them further.
