Java has four different classes: abstract, final, public and default.

• Abstract class cannot be instantiated and is used as a base class for other classes

• Final class cannot be inherited and is used to prevent further modification

• Public class can be accessed from anywhere in the program

• Default class can only be accessed within the same package

• Example: public class MyClass {}

Creating public and private classes in Java is useful for encapsulation and access control.

• Creating a class as public allows it to be accessed from any other class.

• Creating a class as private restricts its access to only within the same class.

• Public classes are typically used for classes that need to be accessed by other classes or modules.

• Private classes are typically used for helper classes or internal implementation...read more
