class Person {
private String name;
private int age;
public void setName(String name){this.name=name;}
public void setAge(int age) {this.age=age;}
public String getName(){return name;}
public int getAge(){return age;}
public String getInfo() {
return "Name: "+ name + "\n" +"age: "+ age;
}
}
class Student extends Person {
private String school;
public String getSchool() {return school;}
public void setSchool(String school)
{this.school =school;}
public String getInfo() {
return "Name: "+ getName() + "\nage: "+ getAge()
+ "\nschool: "+ school;
}
}
public class TestOverWrite {
public static void main(String arg[]){
Student student = new Student();
Person person = new Person();
person.setName("none");
person.setAge(1000);
student.setName("John");
student.setAge(18);
student.setSchool("SCH");
System.out.println(person.getInfo());
System.out.println(student.getInfo());
}
}
程序如上，对于private的话只有同一个类内部才能访问，那为啥子类student能够通过调用方法访问并修改基类person中private的内容呢。。求助。。
