1. Introduction
1.1 What is Java
Java is a groundbreaking computing platform released by Sun Microsystems in 1995. It enables the same application to run on lots of different computers and devices. Java accomplishes this because the source code is translated to byte code (an intermediate code) and then interpreted by the Java Virtual Machine. Therefore, any computer with the JVM can execute a Java program. The process Java uses to execute programs is called a hybrid implementation system. It is called a hybrid because it is a compromise between compilers and pure interpreters implementation systems. This allows faster interpretation, but Java is still up to 20 times slower than C/C++.
