Java – a breed that rocked the world of programming

Back in those old days, programming wasn’t that fun and interesting and proved to be extremely time-consuming. Most of the developers of those days should have gone through arithmetic errors and memory leaks flooding throughout their programs. No space to port even between different versions of the same operating system. That’s hell lot of problem. But, java changed all that. Not just because it uses object-oriented paradigm, but it embraced sound ideas in a practical format that had taken the programmers job to wonderland.

Firstly, it is enviable for its platform-independency and flexibility. Unlike traditional languages where a particular logic is followed, you can create your program in million ways with the help of Java. One of the most important features of Java is that, it adopted features from several other programming paradigms. When this revolutionary programming language was introduced, it was named as Oak and it got the following key features adopted from other languages.

Object Class

Java has one base class named ‘Object’ which is inherited from all the other classes. This was adopted from then available programming language called Smalltalk.

Compile-time Checking

Java programs are subjected to strong static type checking during the compilation time. This helps to improvise the debugging and compilation processes. This feature in java is inherited from another programming language called ‘Ada’.

Multiple Interfaces

One of the most important features of Java is multiple interfaces and single implementation inheritance. Features like these are adopted from the other leading object-oriented language called Objective – C. (Note: Objective is the programming language used for building applications for Apple’s Macintosh computers, iPhones, and iPads.

Inline Documentation

Java programming language allows developers to use Inline documentation. This useful attribute is inherited from a language called ‘CWeb’

JVM and JIT

Java programs are compiled and executed with the help of a virtual machine called JVM and interpreter called JIT. This Java Virtual Machine (JVM) plays an important role in platform independent feature of Java. Both JVM and JIT (Just in Time) Compiler concepts are derived from a programming language, Smalltalk.

Garbage Collection

In Java, the memory consumption and usage are optimized and memory leaks are extremely minimized. This is the because of the implementation of Garbage Collection. Java Garbage Collector keeps freeing up the memories locked in an unused object which helps in saving lots of memory in runtime. This extraordinary feature is inherited from a programming language known as LISP.

Primitive Types and Control Structures

Though Java is object oriented, it can’t be termed as purely object oriented because of the fact that inherits features from a structured programming paradigm. Yes, Java uses primitive data types and control structures which are not part of object oriented concepts. These features are derived from a popular structural programming language called ‘C’.
