`throws`, `try`, and `catch` are keywords in Java used for exception handling.
`throws` is used in the method signature to declare that a method may throw an exception. This is used to notify the caller of the method that they need to handle the exception.
`try` is used to enclose a block of code that may throw an exception. If an exception is thrown within the `try` block, the program will jump to the `catch` block.
`catch` is used to catch an exception that has been thrown by the `try` block. It allows for the programmer to handle the exception in a specific way.
Together, these keywords allow for the programmer to handle exceptions gracefully and prevent the program from crashing.
