Question

设计Teacher类，继承Person类，用java编写。各位高手帮忙。越简单越好。

Answer 1

父类Person要用proteced才能让子类继承。

public class Teacher {
private int teachId;
private String school;

public Teacher(int teacherId) {
super();
this.teachId = teacherId;
}

public String getSchool() {
return school;
}

public void setSchool(String school) {
this.school = school;
}

public int getTeachId() {
return teachId;
}

public void setTeachId(int teachId) {
this.teachId = teachId;
}

}

class Person{
protected String name;
protected char sex;

protected String getName() {
return name;
}
protected void setName(String name) {
this.name = name;
}
protected char getSex() {
return sex;
}
protected void setSex(char sex) {
this.sex = sex;
}

}

Answer 2

public class Person {
protected String name;
protected String gender;
protected int age;
public Person(){}
public String getName() {
return name;
}

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

public String getGender() {
return gender;
}

public void setGender(String gender) {
this.gender = gender;
}

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}

}
class Teacher extends Person{
private int salary;

public int getSalary() {
return salary;
}

public void setSalary(int salary) {
this.salary = salary;
}
}
