Role of Java in Android App Development

Java: A turnover  in the Industry

 Currently, the impact made by Java in the high-tech industry is massive due to its features and advantages. The major factor why developers prefer Java is because of its promise to “Write once and run anywhere”. It is used on a large scale for mobile applications due to its portability and scalability. It is a platform-independent open-source programming language. Moreover, Java has automatic memory management and multi-threading capabilities that handle complex data smoothly. The applications are mostly compiled to bytecode that can run on any Java Virtual Machine (JVM) disregarding the computer architecture.

Some other languages such as C and C++ can also be used for developing Android applications using the Native Development Kit (NDK). C is not mostly preferred by the developers as it lacks security features. Similarly, Java is preferred over C++, it performs well in handling more complex tasks.  Java’s garbage collection facilitates effortless memory management. It reduces the errors acquired by releasing memory, thereby reducing security risks. In this blog, we will explore the complete understanding of Android app development with Java

 Why prefer Java for Android Application Development

 Java is an open-source programming language used majorly for Android application development because the back-end logics are written in Java. Back-end logic is the set of rules that handles the exchange of data between the user interface and the database. The code is portable, it can run on any platform such as Windows, Linux, and Mac. It is an Object-Oriented Programming language and is the main reason for preferring it over other languages.

Object-Oriented Programming language also known as OOP,  is a programming model that creates software designs around objects or data.  Moreover, it prefers using classes and objects instead of using pointers which manage the memory manually, ignoring chances of unwanted interference. Inheritance allows developers to reuse the code, hence saving abundant time and effort in the application development process. Also, inheritance provides comfort to the developers, as it reduces the complexity by avoiding multiple inheritance. Concurrency is also known as Multithreading which allows multiple threads to run at a time. It helps to perform tasks simultaneously resulting in reducing the chances of crashing the app. In the concept of multithreading, multiple threads run on multiple CPUs resulting in faster outcomes when compared to a uniprocessor system.

Case Studies of Android Applications Using Java

 Top companies such as Netflix, Spotify, and Twitter preferred to build their applications interactively. The main reason for preferring the G1 garbage collector is because of its high performance and pause time goals. At the scale of the companies, better CPU utilization is a big deal in terms of cost benefits. G1 is also called Garbage First, it focuses on emptying and collecting these regions, which results in a large amount of free space. The main principle of companies preferring because it is user-friendly and provides type security. Type security gets every single potential mistake at arranging time instead of getting it in the runtime like Python. Type security makes it simpler to see huge applications at last. Moreover, it is a pure Object-oriented language that boosts good software design practices like encapsulation, Inheritance, and polymorphism. Furthermore, it promotes code reusability making it easier to maintain and extend applications.

For mobile Application development, Dalvik Virtual Machine (DVM) is mostly preferred. The mobile application in runs on a DVM for memory, security, and process management. The major principle of DVM is that it runs on low-memory mobile devices. One of the major advantages of using DVM in Android is it follows the register-based model which is much faster when compared to the stack-based model. In DVMs, the data is stored based on the registers of the CPU and there are no PUSH or POP operations performed. Java Virtual Machine (JVM) is preferred mostly over DVM, DVM is designed to run on low-memory devices.

 Conclusion

In conclusion, Java plays an important role in Android app development. Programs that are used in Android app development are written in Java and executed through the DVM. Furthermore, it is very user-friendly and it has a lot of built-in functions that hand over outstanding user experiences. The Java app development services company serves the best outcome in empowering the business to focus on modification according to the business needs. Moreover, it provides the utmost security, as it includes a large set of Application Program Interfaces (API), tools, algorithms, and protocols. Methods are used in for code reusability and it is also used for breaking a complicated program into smaller chunks of code. Data structures define how data is organized, managed, and stored in memory and it is mainly used for enhancing performance. Its strong community support assures that applications can grow and expand according to the business needs without compromising performance or durability.
