The Java programming language is a state-of-the-art, object-oriented language that has a syntax similar to that of C.

The Java platform is just as important as the Java programming language and the Java Virtual Machine. All programs written in the Java language rely on the set of predefined classes.

Some important Permission classes by the core Java platform and summarizes the permissions they represent.

The classes of the Java platform are collected into related groups, known as packages. Most programs manipulate text in one form or another, and the Java platform defines a number of important classes and interfaces for representing, formatting, and scanning text.

In the table There Some Classes Display. there is more available to use of security enhancement. Jave Permission Classes need to security of clients and users to data protection.
