There were five primary goals in the creation of the Java language:
- It should be “simple, object oriented, and familiar”.
- It should be “robust and secure”.
- It should be “architecture neutral and portable”.
- It should execute with “high performance”.
- It should be “interpreted, threaded, and dynamic”.
The syntax of Java is largely derived from C++. Unlike C++, which combines the syntax for structured, generic, and object-oriented programming, Java was built almost exclusively as an object oriented language. All code is written inside a class and everything is an object, with the exception of the intrinsic data types (ordinal and real numbers, boolean values, and characters), which are not classes for performance reasons.
