The concepts of classes and objects, properties, and methods in object-oriented objects have been analyzed earlier. Let's learn how to define a class. For example, there is a student class, there are age, name and other attributes, there is a way to learn, eat.

The code is as follows:

public class person{

String name;

int age;

public void Study () {

System.out.println ("learning");

}

public void Eat () {

System.out.println ("being eaten");

}

}

The above defines a person class, the public class person

Public is open, class is a keyword, a class is defined, the person is the class name

String name;//defines the property name, which is a string

int age;//definition attribute age, type is int type

public void Study () {

System.out.println ("learning");

}

public void Eat () {

System.out.println ("being eaten");

}

The above respectively defines the study method and the Eat method, respectively printing is learning and is eating.
