The Advantages of Java Programming Language


Performance

Java is an interpreted language therefore faster than most compiled languages.

A Java program is compiled into a byte code and stored in a class file. The class files are loaded in a Java Virtual Machine (JVM). The virtual machine’s performance is optimized by

  1. Just-in-time-compiling: Implementation of the Hotspot Architecture in the Java Virtual machine. the JVM continuously analyses program performance for parts that are executed frequently which are targeted for optimization leading to high performance execution with minimum overhead for less-critical code.
  2. Adoptive Optimization: Dynamic recompilation of program parts based on execution profile.
  3. Garbage collection: A memory management system. Its main objective is to free up occupied memory that is no longer referenced by any reachable Java object

Support for Object oriented programming

In Java programming there’s more focus on data and methods other than procedure. This hence promotes the language’s flexibility and improved software modularity and maintainability.


Support for Networking & Communication

During Java’s development, Sun’s corporate motto has always been “The network is the computer.” The designers of the Java platform believed in the importance of networking and designed the Java platform to be network-centric. From a programmer’s point of view, Java makes it unbelievably easy to work with resources across a network and to create network-based applications using client/server or multitier architectures. This means that Java programmers have a serious head start in the emerging network economy.

Slack, one of the most popular workplace/productivity applications, uses Java for it’s messaging server that handles web-sockets and gateway connections.


Portability

Java applications are called WORA(Write once run anywhere ). This means that an application can be written on one machine and can run in any other Java enabled system making it architecture-neutral.

Anywhere, that is, that supports the Java platform. Fortunately, Java support is becoming ubiquitous. It is integrated, or being integrated, into practically all major operating systems. It is built into the popular web browsers, which places it on virtually every Internet-connected PC in the world. It is even being built into consumer electronic devices, such as television set-top boxes, PDAs, and cell phones.


Security

Both the language and the platform were designed from the ground up with security in mind. The Java platform allows users to download untrusted code over a network and run it in a secure environment in which it cannot do any harm: it cannot infect the host system with a virus, cannot read or write files from the hard drive, and so forth. This capability alone makes the Java platform unique.
