  2. To learn core Java, you must have the basic knowledge of C/C++ programming language. C/C++ 2

  3. What is java and why to use java ? What is Java? Java is a programming language and a platform. Java is a high level, robust, object-oriented and secure programming language. Java was developed by Sun Microsystems (which is now the subsidiary of Oracle) in the year 1995. James Gosling is known as the father of Java. Before Java, its name was Oak. Since Oak was already a registered company, so James Gosling and his team changed the name from Oak to Java. Platform: Any hardware or software environment in which a program runs, is known as a platform. Since Java has a runtime environment (JRE) and API, it is called a platform. 3

  21. Is Java Good For Android Mobile Apps Development? 100% yes. Java programming language is one of the most accepted languages for mobile apps development. It is the first choice of mobile app developers to create native android mobile apps and web apps. Its platform independence, libraries, easy to write, compile and debug features, high security, and cross- platform capabilities making it an ideal and the best programming language for web and mobile apps development. 21

  22. Why Is Java Declared As Official Language for Android Development? Though its initial version is released in 1995 was for web applications development, its robustness, code simplicity, and community support made it the most popular programming language for mobile app development. There are more other reasons why java is used for android development. Before executing the Android code, it needs to be compiled several times to optimize the code for ensuring better performance. Java’s platform-independent or architectural neutrality feature makes the code run on different platforms. These are the topmost significant reasons behind the increasing use of Java for Android Apps Development. Herein, we have also gathered a list of the best mobile applications that were developed using Java language. If you are looking to invest in mobile apps development using Java, we help you in cloning or developing on-demand or trending android mobile applications using Java. . 22

  23. Conclusion The Java programming language is the most critical language for Android app development as well as software engineering. This language allows developers to write simple code that works smoothly across multiple mobile platforms. There are applications of Java in the real world in many different fields such as gaming, iAnstant messaging, music streaming, and trading 23

  34. S i m p l e Java is very easy to learn, and its syntax is simple, clean and easy to understand. According to Sun Microsystem, Java language is a simple programming language because: Java syntax is based on C++ (so easier for programmers to learn it after C++). Java has removed many complicated and rarely-used features, for example, explicit pointers, operator overloading, etc. There is no need to remove unreferenced objects because there is an Automatic Garbage Collection in Java.
