What are the scope of Java Technologies for Web Applications? Java is based on object model hence it is one the popular programming language. Why Java is so popular programming language? Java doesn’t support pointers and operator overloading concept. How Java different to C++ ? C++Ĭ++ support pointers and operator overloading. Along with this Java also works with three OOPs concept Q3. There are 4 major concept in Java that is abstraction, encapsulation, polymorphism, and inheritance. Java is simple to learn programming language because doesn’t contain concepts like : Pointers and operator overloading and it is secure and portable. Major MNC companies are recruiting Java Programmers. Like C++, Java does static type checking, but Python does not.Īccording to report of Java is most demanded programming languages after JavaScript by recruiters worldwide in 2024. The programs are written in Java typically run faster than corresponding Python programs and slower than C++. When compared with Python, Java kind of fits between C++ and Python.One more example, since there are no pointers, bad memory access is also not possible. So we cannot pass large objects (like we can do in C++) to functions, we always pass references in Java. For example, non-primitives are always references in Java. When compared with C++, Java codes are generally more maintainable because Java does not allow many things which may lead to bad/inefficient programming if used incorrectly.Java is used in all kinds of applications like Mobile Applications (Android is Java-based), desktop applications, web applications, client-server applications, enterprise applications, and many more.Also, Java codes are always written in the form of classes and objects. But Java does not provide low-level programming functionalities like pointers. Then the byte code runs on Java Virtual Machine (JVM) regardless of the underlying architecture. The Java codes are first compiled into byte code (machine-independent code).However, it is not considered as pure object-oriented as it provides support for primitive data types (like int, char, etc) Java has been one of the most popular programming languages for many years.Java is one of the most popular and widely used programming languages. ![]() ![]() ![]() ![]()
