In fact, you can directly start learning Java without any prior knowledge of programming language. But, the syntax in Java is similar to the syntax of the C programming language, therefore, Knowing C language helps to get hold of Java quickly. Having introduced to object-oriented principles before starting Java, also helps in the understanding of the language so, having an idea on object-oriented languages such as C++ also helps. In short, if you know C or C++ it will be a little bit easier to cope with Java technology.

It is not advisable to use CX_ROOT directly and you would require using one of its direct subclasses. Also, the propagation depends upon the exception subclass hierarchy.Subclasses of CX_STATIC_CHECK – these do not propagate automatically. You will need to do the handling yourself or there will be a syntax error in the program.Subclasses of CX_DYNAMIC_CHECK – these do not require any handling. But the program that does not handle the exception will be aborted with these subclasses.Subclasses of CX_NO_CHECK – These will get propagated automatically if the exception is not handled.
