GNU Classpath is a free software implementation of the standard class library for the Java programming language.Most classes from J2SE 1.4 and 5.0 are implemented. Classpath can thus be used to run Java-based applications.
Exception chaining, or exception wrapping, is an object-oriented programming technique of handling exceptions by re-throwing a caught exception after wrapping it inside a new exception. The original exception is saved as a property (such as cause) of the new exception. The idea is that a method should throw exceptions defined at the same ...
