What is static class in Java with example?

We can declare a class static by using the static keyword . A class can be declared static only if it is a nested class. It does not require any reference of the outer class. The property of the static class is that it does not allows us to access the non-static members of the outer class.

Java supports Static Instance Variables, Static Methods, Static Block, and Static Classes . The class in which the nested class is defined is known as the Outer Class. Unlike top-level classes, Inner classes can be Static. Non-static nested classes are also known as Inner classes.25 Şub 2022

A static class can be used as a convenient container for sets of methods that just operate on input parameters and do not have to get or set any internal instance fields . For example, in the . NET Class Library, the static System.

Static classes are basically a way of grouping classes together in Java . Java doesn’t allow you to create top-level static classes; only nested (inner) static classes. … We don’t need an instance of the outer class to create an object of a static inner class.

A static inner class is a nested class which is a static member of the outer class . It can be accessed without instantiating the outer class, using other static members. Just like static members, a static nested class does not have access to the instance variables and methods of the outer class.9 Şub 2018
