7일 차 중간점검(클래스를 이용한 getter/setter)

Student클래스를 작성

멤버변수로 이름, 나이, 성적 각 변수에 대한 getter/setter작성

상태를 확인할 수 있는 toString작성

----------------------------------------------------------------------------

import java.util.Scanner;

class Student {

private String name;

private int age;

private int score;

public void setName(String name) {

this.name = name;

System.out.println("이름은 " + name + " 입니다");

}

public String getName() {

return name;

}

public void setAge(int age) {

if (age > 0) {

this.age = age;

System.out.println("나이는 " + age + " 입니다");

}

}

public int getAge() {

return age;

}

public void setScore(int score) {

if (score > 0) {

this.score = score;

System.out.println("점수는 " + score + " 입니다");

}

}

public int getScore() {

return score;

}

public String toString() {

return "이름 : " + name + ", 나이 : " + age + ", 점수 : " + score;

}

}

public class Test14 {

public static void main(String[] args) {

Student myStudent = new Student();

myStudent.setName("박성욱");

myStudent.setAge(25);

myStudent.setScore(90);

System.out.println(myStudent);

}

}

==============================================================

Employee 클래스를 작성하여

이름, 연봉, 근속연수 getter/setter toString 작성

class Employee {

private String name;

private int yearsMoney;

private int service;

public void setName(String name) {

this.name = name;

System.out.println("이름은 " + name + " 입니다");

}

public String getName() {

return name;

}

public void setyearsMoney(int yearsMoney) {

if (yearsMoney > 0) {

this.yearsMoney = yearsMoney;

System.out.println("연봉은 " + yearsMoney + " 입니다");

}

}

public int getyearsMoney() {

return yearsMoney;

}

public void setservice(int service) {

if (service > 0) {

this.service = service;

System.out.println("근속연수는 " + service + "년차 입니다");

}

}

public int getservice() {

return service;

}

public String toString() {

return "이름 : " + name + ", 연봉 : " + yearsMoney + ", 근속연수 : " + service;

}

}

public class Test15 {

public static void main(String[] args) {

Employee myStudent = new Employee();

myStudent.setName("박성욱");

myStudent.setyearsMoney(250000000);

myStudent.setservice(2);

System.out.println(myStudent);

}

}
