Use various Java programming language constructs to create several Java technology applications. The Java platform provides a security architecture which is designed to allow the user to run untrusted bytecode in a “sandboxed” manner to protect against malicious or poorly written software. The Java platform consists of several programs, each of which provides a portion of its overall capabilities. For example, the Java compiler, which converts Java source code into Java bytecode , is provided as part of the Java Development Kit . The Java Runtime Environment , complementing the JVM with a just-in-time compiler, converts intermediate bytecode into native machine code on the fly. The Java platform also includes an extensive set of libraries. These are some very basic project management skills required for the job.
