Enroll Java programming online course with H2K Infosys

In recent information technologies, various computer programming got great hype now. Are you looking to learn Java programming online? For creating web apps, Java is a popular programming language. It is an object-oriented, network-centric, multi-platform language that may be used as a platform. For creating anything from enterprise software and mobile apps to server-side technologies and massive data applications, it is a quick, secure, and reliable programming language. The Java language uses the keyword "Static". Don't get confused so you can go for the best computer training centers and do the Java programming online course effectively, saving you time. Here H2kInfosys guide you to the introduction to static keywords in Java in this post.

What is Static Keyword?

The static keyword's primary purpose in Java is memory management. It serves as a keyword to designate a variable or method that can be used with many classes. Generally speaking, the term "static" describes a constant variable or method that is relevant to each instance of a class. Typically, a class's primary method is designated as static. You must use the keyword static before declaring any objects that will be static.

Types of Static Keywords in Java

Static is a non-access modifier in the Java programming language that can be applied to the following types, and to learn this in more detail, you can join the Java online courses in the best training centers.

Static Block

Static Variable

Static Classes

Static Method

Java Static Block and its applications

When a class is loaded into memory, a static block is a collection of instructions that is only ever run once. The term "static initialization block" can also refer to a static block. Because it is a choice, the class can be initialized or set up at run-time. It is the main and first executed method in the Java programming class.

When a particular class is run, the Java virtual machine executes two operations.

The dot class file in byte code is first loaded into memory by the JVM, which is how the class is created.

Static blocks are executed while a dot class files loads into memory. After the dot class file has loaded, the primary method is called and executed. The static block is therefore run before the main procedure.

Static variable in java and its application

The static variable can refer to an attribute shared by all objects and is not specific to each object, For example, the name of the employer for employees or the school for students. You can use it only once during class loading and the static variable receives memory in the class area. Java's memory management is where the static keyword is primarily applied. When we use the static keyword before initializing a class's methods or variables, the class owns these static methods and variables rather than their instances or objects.

Static Classes in Java

In Java, a static class is a nested class that doesn't require a reference to the outer class. Only the static members of its outer class are accessible to static classes. A static class is unable to access an outer class's non-static members. The members of the outer class that are static and non-static are accessible to the inner classes. It is mainly employed to control memory. A method of combining classes is to use the static class. The class loader does not load the static classes concurrently with the enclosing class and rather, it does so only when they are first used.

Java Static method

Instead of being a class instance, a static method is part of the class itself. As a result, you can call a static method without first generating a class object. Sometimes, class methods are used to refer to static methods.

Utility classes that provide methods for various purposes can be made using static methods.

Because they can only be used within the class in which they are declared, static methods can enforce encapsulation.

Bottom Line

Java programming plays a major in the information technology field. Hope you gain knowledge with H2k Infosys classes about the basics introduction and application of static keywords in Java.
