  • Architecture-neutral

    Java is architecture neutral because there are no implementation dependent features, for example, the size of primitive types is fixed. In C programming, int data type occupies 2 bytes of memory for 32-bit architecture and 4 bytes of memory for 64-bit architecture. However, it occupies 4 bytes of memory for both 32 and 64-bit architectures…

  • Robust

    The English mining of Robust is strong. Java is robust because: It uses strong memory management. There is a lack of pointers that avoids security problems. Java provides automatic garbage collection which runs on the Java Virtual Machine to get rid of objects which are not being used by a Java application anymore. There are…

  • Secured

    Java is best known for its security. With Java, we can develop virus-free systems. Java is secured because: No explicit pointer Java Programs run inside a virtual machine sandbox Classloader: Classloader in Java is a part of the Java Runtime Environment (JRE) which is used to load Java classes into the Java Virtual Machine dynamically. It…

  • Portable

    Java is portable because it facilitates you to carry the Java bytecode to any platform. It doesn’t require any implementation.

  • Object-oriented

    Java is an object-oriented programming language. Everything in Java is an object. Object-oriented means we organize our software as a combination of different types of objects that incorporate both data and behavior. Object-oriented programming (OOPs) is a methodology that simplifies software development and maintenance by providing some rules. Basic concepts of OOPs are: Object Class Inheritance Polymorphism…

  • Simple

    Java is very easy to learn, and its syntax is simple, clean and easy to understand. According to Sun Microsystem, Java language is a simple programming language because: Java syntax is based on C++ (so easier for programmers to learn it after C++). Java has removed many complicated and rarely-used features, for example, explicit pointers,…

  • Futures Overview

    Features of Java The primary objective of Java programming language creation was to make it portable, simple and secure programming language. Apart from this, there are also some excellent features which play an important role in the popularity of this language. The features of Java are also known as Java buzzwords. A list of the most important…

  • Overridden Methods of the superclass

    If methods with the same name are defined in both superclass and subclass, the method in the subclass overrides the method in the superclass. This is called method overriding. Example 1: Method overriding Output In this example, by making an object dog1 of Dog class, we can call its method printMessage() which then executes the display() statement. Since display() is defined in both the classes, the…

  • Create an enum class

    Java program to create an enum class Output In the above example, we have created an enum class named Size. The class contains four constants SMALL, MEDIUM, LARGE, and EXTRALARGE. Here, the compiler automatically converts all the constants of the enum into its instances. Hence, we can call the method using the constant as objects. In this call, the this keyword is…

  • Print object of a class

    Java program to print the object Output In the above example, we have created an object of the class Test. When we print the object, we can see that the output looks different. This is because while printing the object, the toString() method of the object class is called. It formats the object in the default format. That…
