Simple and easy to grasp

For programmers, the introduction of java is to be basic and simple. Other programming languages, such as C++, are fixing and saved using it. One cause is its programmed garbage collection and memory task mechanism. Why it is easier to learn and use than other programming languages. Other programming languages, but, need programmers. They help in organizing garbage and divide memory.


Multi-threaded creating computer programs depend on it by default. But, other languages need an OS precise system to enable it. It is an important part of visual programming and organizing.
