Major Features of Java Programming Language

 

Java means that developers who switch to Java won't have any issue in terms of syntax. Second, the notion of pointers has been eliminated from Java which can cause confusion for the programmer. Furthermore, pointers can be vulnerable to security.

Object-Oriented

Java is an Object Oriented Programming Language, that is to say, in Java all programming is done using objects and classes. What is an object? It is an actual entity in the world that could represent any individual or place and be distinct from other objects. Each object around us is a part of a state or behaviors that is associated with it. For instance, my mobile phone is a real thing and is a state that includes things like model, color, brand quality of camera, etc These properties are represented in variables. Mobile is also associated with activities like calling or messaging, taking photos and so on. These actions are represented through methods that are implemented in Java.

Platform Independent

The primary goal of Javasoft people is to create a language that works on every platform. Platform refers to a form of operating system or hardware technology. Java lets programmers create programs on any computer that has a configuration of their choice and execute it on any machine that has different configurations.

Portable

The WORA (Write Once Run Anywhere) concept and the platform-independent feature makes Java accessible. Today, using Java, the Java programming language programmers are able to achieve the same results regardless of the device, simply through writing code once. The reason is bytecode and JVM. If you write any code using Java and then the code is then converted into equivalent bytecode, which is only accessible by JVM. There are different versions of JVM that work on different platforms. Windows machines come with its own versions of JVM Linux has its own version, and macOS comes with an own edition of JVM. Therefore, if you distribute your bytecode on any device the JVM on the machine will translate the bytecode to the appropriate machine code. So, portability allows programmers to focus on their development and productivity, instead of writing codes for different platforms.

Robust

Java is a Java Programming language is robust that is, it is capable of handling sudden end of a program. There are two reasons for this. The first is that it comes with a crucial and beneficial feature called Exception Handling. If an exception occurs within Java code, then nothing occurs, however, in other languages with low-level programming the program may be unable to function properly. Another reason that Java is a great language is its features for managing memory. As opposed to other low-level language, Java offers a running time Garbage collector provided by JVM that takes all the variables that aren't being used. Garbage collector is a specific application running on JVM that runs on a regular basis and finds any unneeded objects or variables and then removes the objects from memory in order to free up space.
