What is Java? Is Java still relevant in 2021?
Java,one of the most widely used programming languages,is used as the server-side language for most back-end development projects, including big data and Android development. Java is also widely used in desktop computing, mobile computing, gaming, and numerical computation. As can be seen, Java is the cornerstone of the digital revolution.
Java is now the market leader in the enterprise back-end market and the android mobile application development industry. After considering the combination of newer language choices such as lambda expressions and streams in JDK 8, the long term appears promising for Java.
Why is Java so popular even today?
One of the primary reasons for Java’s popularity is its platform independence, which means that Java programs can operate on a wide range of systems. A Java program may execute on any machine with a Java Runtime Environment, often known as a JRE.
What makes Java a powerful programming language in 2021?
Java is a more powerful programming language since it supports pure object-oriented programming. Apart from that, Java supports a wide range of features such as graphics, packages, networking, socket programming, swing packages, and so on.
Java can be used to develop robust apps that can operate on a single machine or be spread across a network of servers and clients. It can also be used to build a small application module or applet that can be embedded in a Web page.
Why is Java Robust?
Java is robust because it can handle runtime errors, offers automated garbage collection and exception handling, and uses the explicit pointer concept. Java has an effective memory management system. It aids in the elimination of errors by checking the code at both compile and runtime.
