Advantages of Java

Simple: Java is very easy to learn and java syntax is very simple and easy to understand, it is based on C++. Java has an Garbage Collection.

Platform Independent: Programming language like C and C++ compiled only on platform specific machine, where java runs on other hardware-based platforms. When we compile java code the java code will be converted into bytecode, we can run the byte code in different platform such as Windows, Mac, Linux, etc.

Object-oriented: Java is an object-oriented programming language. In java, everything is an object.

Robust: Java puts a lot of emphasis on early checking for possible errors. Java has automatic garbage collection mechanism and has the strong memory allocation. Java has the powerful type checking and exceptional handling mechanism comparing to other programming language.

Portable: Java is portable because we can run the java bytecode in different platform.

Automatic memory management: A Java developer does not have to check if there is enough memory to allocate for an object and then deallocate it explicitly, the operations are automatically handled by the garbage collector.
