Java programming language is high-level, general-purpose, object-oriented software. Since 1995, its year of release by Sun Microsystems, Java programming language registered tremendous growth, making it the most popular language globally. As a result, the number of devices running Java applications increased steadily, from 1.6 billion devices in 2004 to about 15.1 billion as of 2016.
A Brief Description of Java Programming Language:
An extensive ecosystem of frameworks and libraries, robustness, and platform independence are some exceptional features that make Java the most popular. To elaborate, programmers can write platform-independent programs in Java, allowing the code to run on any computer. In contrast, platform-dependent technologies do not allow the same code to run on different computers. Notably, high-level programming languages enable humans to interact with the code easily as they resemble human language, making it easy to use.
Java programming language helps develop many applications. It helps develop several applications, including database connections, application servers, web servers, web applications, desktop applications, mobile applications, prominently Android apps, and gaming software. Java programming language can run on all types of platforms or operating systems like Linus, Mac, Unix, Windows, etc.; there are plenty of opportunities in the job market, offering extensive opportunities for career growth.
Java is easy to learn while providing convenience to use. It is free to download as it is available as open-source software. It rates high in powerfulness, fastness, and security on the performance scale. The number of community supporters is also significant. Due to the building of object-oriented concepts, Java enables the framing of a clear structure while coding and allows the reusing of the code while minimizing development costs.
Some key Attributes of the Java:
1. Platform Independence:
Among the various features of Java, platform independence is one of the most powerful features. During the compilation process, the source code is converted first into an intermediate form known as bytecode. Then, the code enters the Java Virtual Machine (JVM), which enables the code to execute on any platform. For this reason, Java programming language is famous as “write once, run anywhere”; this feature allows Java technology to be used across various applications.
2. Automatic Memory Management:
Java programming language supports garbage collection, enabling the automation of memory management. Enhanced security and prevents memory leaks while offering developers a simplified memory management solution.
3. Object-Oriented:
Java programming language is built on object-oriented concepts. Due to this, it supports object-oriented principles like inheritance, encapsulation, and polymorphism.
4. Security:
Java ensures strong security, particularly during data processing from external sources due to the Java Virtual Machine (JVM). The JVM enables bytecode verification to ensure the code generated from external sources does not disturb or damage the host system.
5. Compatible:
Java supports backward compatibility, which means code written in older versions can run on newly released versions only with minor or simple modifications.
6. Open Source:
Java programming language is available as open source, with the source code publicly available. As a result, developers working on Java projects can easily modify and redistribute the code. Due to this feature, Java offers several other benefits, including higher control, flexibility, stability, and security, while lowering the overall costs.
7. Community-based Development:
Java gets support from Java Community Process (JCP), which comprises several developers and organizations actively contributing to Java development. Due to this facility, Java technology remains relevant to the current technological needs.
8. Scalability:
Java exhibits scalability. It means Java programming language can support large-scale systems easily. Due to this feature, Java is the best choice for large organizations that use complex applications.
9. Reliable and Robust:
Java has perfect design and supports the creation of highly reliable application software. Robustness is the potential of a programming language to handle errors while managing and executing the data. In contrast to the C programming language, in Java, pointers are absent for bypassing security dilemmas. Also, Java has strong memory management, enabling it to be robust. Moreover, the automatic garbage collection on the JVM eliminates objects that do not fulfill the criteria to run on Java applications. In addition, exception handling, type-checking mechanisms, and runtime checking contribute to Java programming language being a robust platform. All these features help programmers to write an error-prone code.
10. Multithreading:
Multithreading is another prominent feature of Java programming language. Multitasking and synchronization are possible through multithreading, which means this feature helps develop parallel and concurrent applications. This feature is helpful while developing applications that utilize multi-core processors, such as multimedia and real-time applications.
Java has an expansive standard library with many classes, interfaces, etc., built for use across multiple programming tasks. With this standard library’s offering, Java helps simplify several fundamental programming tasks. The in-built library allows developers to lessen their effort and save time while working on basic functionalities.
