子类继承父类，就会拥有父类的全部方法
在java中，所有类默认继承object类
父类中private的方法，super无法调用
Person
package herit;
public class Person {
protected String name = "delike";
}
Student
package herit;
public class Student extends Person{
//ctrl+h 打开继承树
private String name = "Drake";
public void test(String name){
System.out.println(name);
System.out.println(this.name);
System.out.println(super.name);
}
}
Application
import herit.Person;
import herit.Student;
public class Application {
public static void main(String[] args) {
Student student = new Student();
student.test("德里克");
}
}
run
