Different Types of Classes in Java with Examples 2. Access modifiers for classes or interfaces in Java 3. Private Constructors and Singleton Classes in Java 4. Primitive Wrapper Classes are Immutable in Java 5. Parent and Child Classes Having Same Data Member in Java 6. Utility Methods of Wrapper Classes in Java 7.
Based on the position of declaration and behavior all inner classes are divided into four types. If we are declaring any named class directly inside a class without the static modifier, such a type of inner class is called Normal or Regular inner class.
In Java, we may declare a class by using the class keyword. Class members and functions are declared simply within the class. Classes are required for the creation of Java programs. The object-oriented paradigm (OOP) allows users to describe real-world objects. Also, a class is sometimes known as a user-defined data type.
A class that has zero or more abstract methods and is specified with the abstract keyword is called an abstract class. We must rigorously extend the abstract classes to a concrete class in order to use them because they are incomplete classes. Constructors and static methods can also be included.
