With the ability to run on any system, combined with object-oriented programming, makes Java so compatible with the industry-standard codes for software developments. The object is then used to get the program running.īecause of the intermediate code generation, Java is also platform-independent. The object is hence called the instance of a class. Once it is defined, it needs to be instantiated by making an object of the said class. The class is like a blueprint of what needs to be done. java and used to follow along with the different procedures.
