Is there a way to listen any exceptions in java?
My purpose is creating a library that listens & collects all rised errors in java. Are there any way to do this?

An exception listener allows a client to be notified of a problem asynchronously. Some connections only consume messages, so they would have no other way to learn that their connection has failed. A JMS provider should attempt to resolve connection problems itself before it notifies the client of them.
June 01, 2022. CWE 248-Uncaught Exception occurs when an exception is not caught by a programming construct or by the programmer, it results in an uncaught exception. In Java, for example, this would be an unhandled exception that would terminate the program.
You can catch every uncaught exception via Thread.UncaughtExceptionHandler. If that's not sufficient I would perhaps suggest some AOP/bytecode-weaving solution to implement some watch around each created exception.

I have done some thing similar using Java instrumentation API, Create java agent and Class transformer to catch hold of required Exception class and instrument the byte code as necessary
you can follow up here Using Instrumentation to record unhandled exception
Above links will give you idea of how/when to use ASM or Instrumentation
