What? , When? And Why? Of Java Programming language

Category: Academics

What? Java is a programming language written once and running anywhere and developed by Sun Microsystems. It's similar to C and C++, but much simpler. You can combine Java with many technologies like Spring, Node js, Android, Hadoop, J2EE, etc. to create powerful, scalable, portable and distributed complete applications. Java also encourages continuous integration and testing with tools like Selenium. History of Java Java was originally developed in the early 1990s by James Gosling and his colleagues at Sun Microsystems. It was originally called Project Oak, which had a similar implementation to C and C++. The name Java was then chosen after considerable brainstorming and was based on the name espresso bean. Java 1.0, the first version was published in 1995 with the slogan "write once, runwhere". Sun Microsystems was later taken over by Oracle. From then on there was no turning back. The latest version of Java is Java 12 which was released in March 2019. Java Functions Java offers many interesting functions - • Platform independent language • A comprehensive standard library that makes coding easier. You can create complete stand-alone applications using Java. • Java supports automatic memory allocation and release (called garbage collection). • Offers excellent performance as Java supports multithreading and concurrency, making it a highly interactive and responsive language. • Safe and easy When? The expansion of the Java programming language is very extensive, as evidenced by the claim that 3 billion devices run Java, which was demonstrated during the installation of Java. Java provides a rich and extensive set of APIs to help programmers develop applications. With the help of Java we can develop different applications for different purposes. We can use Java technology to develop the following applications: • Mobile application development • Desktop GUI Application • Web-based application • Game apps • Big data technology • Distributed applications • Cloud based application • IoT Applications Why? Java is isolated from other programming languages in terms of functionality and security and is also compliant. There are several other reasons to use Java: • Scalability: Scalability increases the capacity of our system. It increases system capacity by adding system resources without affecting the deployment architecture. We can achieve scalability by increasing resources like RAM and CPU in a system. This is important because it handles the load, improves system performance, and maximizes productivity. • Cross-platform: Cross-platform means that the compiled Java program can run on all platforms. Remember that the system must have a JVM. After a Java program is compiled, the Java code is converted into platform-independent byte code. This bytecode is understood by the JVM. We can run this bytecode on any platform. • Memory management: Java has its own memory management mechanism known as garbage collection. We don't have to worry about storage and we don't have to implement it to manage storage. It automatically deletes objects when they are no longer used by the application. Increase application speed. • Multithreading: Threads are lightweight sub-processes. Multithreading in Java allows two or more threads to run at the same time. This maximizes CPU usage. Conclusion Java is multithreaded, meaning multiple tasks can be handled simultaneously and users can construct interactive applications that run smoothly. With its secure features, virus-free, tamper-free systems can be developed. Authentication techniques are based on public-key encryption.
