Java is a versatile, object-oriented, and widely used programming language known for its robustness, platform independence, and rich ecosystem of libraries and frameworks. Developed by James Gosling in the 1990s, Java has been a foundational language in the world of software development. Java is renowned for its cross-platform nature; all Java code would need was the Java Virtual Machine (JVM) to be installed, and it was good to go on any platform. This meant that most applications developed in Java were inherently cross-platform, making it an attractive choice for developers who want their code to reach as many users as possible. Much like C#, Java is a highly object-oriented programming language, with emphasis on the use of objects and classes. Much like most languages that rely on runtime environments like JVM, Java has a built-in memory manager and garbage collector, meaning that developers do not have to deal with memory management. This makes Java more secure than languages like C++ because the risk of security vulnerabilities like buffer overflows is substantially reduced, as are other memory-related bugs.
In addition to memory management, Java has other built-in features that can make Java applications more secure, including JVM bytecode verification to ensure that untrusted code from the internet is not automatically executed in the JVM. Java comes with an extensive standard library, which includes code for handling data structures, input/output, networking, and much more. Having a feature-rich standard library means Java developers do not have to waste time creating boilerplate code; they can just include code in the standard library to do a wide range of tasks. In addition to this, Java supports multi-threading, enabling developers to write concurrent and efficient applications. The Java Concurrency Framework provides tools for managing thread synchronization and other concurrency-related elements.
Commonly used in enterprise development, Java is ideal for businesses to run their code on. Java is used in large-scale web applications, backend services, and server-side applications due to its reliability and security. Java is used in web development with frameworks like Java EE, Spring, and JavaServer Pages; these enable the creation of modern, dynamic data-driven web applications. Today, Java is one of the main languages in Android application development and has become the standard development language in Android Studio. This makes learning Java a must for Android developers. In addition to Android development, Java is also used to develop games, although it is not as popular as it used to be. One of the most popular games in the world, Minecraft Java Edition, was developed using Java.
Java is a highly versatile, reliable, and secure programming language used in a wide range of different applications, including legacy code bases. Here is a list of Java's most popular use cases:
Java enables developers to produce code that is reliable and secure, which makes it the perfect option for developing server-side applications like web applications and database applications. Developers who want to produce a codebase that will last a long time with little maintenance often turn to Java because of its reliability. In addition, Java's JVM security and memory manager make Java code more secure and bug-resistant. Java is also the standard for developing Android applications, and it will most likely stay this way for the time being. All of this makes Java a viable language in the modern day and a reliable and time-tested language for software developers.
