新手问题！求解决
谁知道这代码错在哪了啊？搞了半天也没找出来。

class Person{
private String name;

void setName(String n){
this.name = n;
}


String getInfo(){
return "name is"+ this.name;
}
}

class Student extends Person{

private String school;

void setSchool(String s){
this.school = s;
}
String getInfo(){
return "name is "+ name + "; school is " + school;
}
}

public class TestPrivate{
public static void main(String[] args){
Person person = new Person();
Student student = new Student();
student.setName("bill");
student.setSchool("Peking University");
System.out.println(student.getInfo());
}
}

[解决办法]
private String name;改成protected String name;才能在子类里直接访问name
[解决办法]
name是private的，只能在声明这个变量的类中使用，所以可以在Person中添加一个public方法：
public String getName() {
return name;
}

然后Student的getInfo改为：
String getInfo() {
return "name is " + getName() + "; school is " + school;
}
[解决办法]

Java code

class Person {    private String name;        void setName(String n) {        this.name = n;    }    String getName() {        return name;    }    String getInfo() {        return "name is" + this.name;    }}class Student extends Person {    private String school;    void setSchool(String s) {        this.school = s;    }    String getSchool() {        return school;    }    String getInfo() {        return "name is " + this.getName() + "; school is " + this.getSchool();    }}public class TestPrivate {    public static void main(String[] args) {        Person person = new Person();        Student student = new Student();        student.setName("bill");        student.setSchool("Peking University");        System.out.println(student.getInfo());    }}

private私有变量不能被子类直接使用，也可以在Person添加getName方法，然后在子类中直接调用
