∙ 14y agoJava allows us to create many types of classes. Below are some commonly used classes.
a. Public - these are the most common classes. Any class that contains a public keyword in its declaration is a class that can be saved with the file name that equals the class name. these are the java classes that get created most of the time and can include all types of functionalities provided by java.
b. Abstract - The abstract class will have only method declarations and no definitions. So any class that extends this abstract class would have to provide the method definitions. This way you can ensure that all these classes will have a similar set of methods/features.
c. Singleton - These classes can be instantiated only once and for the whole application there will be only one instance of the class.
d. Inner Class - A class that is declared inside another public class (explained in point A)
