Java has become the most widespread object oriented language that is being used to develop softwares and applications for companies. Though there are various other languages available, developers and programmers prefer Java on them when it comes to developing apps and softwares.
Java has become the most widespread object oriented language that is being used to develop softwares and applications for companies. Though there are various other languages available, developers and programmers prefer Java on them when it comes to developing apps and softwares. Java, an open source programming language has an edge over other language, it provides various features that helps developers in their work, which no other language provides.
Java is being used to develop software for railway system, metro system, airplane system, etc.
Here we look at all those features of Java that makes it the first choice of programmers and developers:
- Platform independent
- High Performance
Java is explicitly simple to code in. Programs are easy to write and debug. Also Java provides the bug free system and it is almost impossible to crash a Java program. Java has a strong memory management system
Java is based on Write-Once-Run-Anywhere concept that makes it Platform independent. It is one of the important features of the language and makes it preferable among developers looking for language where they can write a program and then run it on different operating system. Java is platform independent because the program written in it is not directly converted into machine code but instead is converted into byte code by Java compiler, this byte code is then converted into machine readable code by Java Virtual Machine (JVM). JDK including JVM must be installed in a platform.
Java is considered one of the most secure programming language. It is very hard to crack or hack or crash the programming written in Java. While the security manager determines the accessibility options of a class, public key encryption system allows the java applications to transmit over the internet in the secure encrypted form and bytecode Verifier checks the classes once they are loaded.
Java has the strong memory allocation and automatic garbage collection mechanism. Java remains secured from crash as Compiler constantly checks the program for error and interpreter checks for any run time error. Java has an exception handling and type checking mechanism as well.
Java uses the lightweight process called threads that makes its performance faster. Java compiler uses the Just-in-Time compilation technique that improves the performance
Another feature of Java is Multithreading, which means a single program is divided into multiple threads that are executed independently at the same time. This makes the work faster and quicker. The execution of multiple threads takes place according to the code written in a program. In multithreading, not even a single thread disturbs the execution of other thread.
