Java offers three ways to catch multiple exceptions: using multiple catch blocks for different exception types, the multi-catch feature to handle multiple exceptions in a single block, and a catch-all block for general exception handling. Let’s look in depth at each. Use multiple catch blocks ...
In java, when we handle more than one exceptions within a single try {} block then we can use multiple catch blocks to handle many different kind of exceptions that may be generated while running the program. However every catch block can handle only one type of exception. This mechanism is...
If a catch block handles multiple exceptions, you can separate them using a pipe (|) and in this case, exception parameter (ex) is final, so you can’t change it. The byte code generated by this feature is smaller and reduce code redundancy. Java rethrow exception Another improvement is ...
