TestCalenderModelA实现main方法，具有输入大赛起始和终止日期，输出日历，并计算大赛周期的功能。程序文件TestCalenderModelA .java。 import java.util.Scanner;
public class TestCalenderModelA {
public static void main(String[] args) { } }
Scanner scan = new Scanner(System.in); System.out.print(\请输入年份:\int year = scan.nextInt(); System.out.print(\请输入月份:\int month = scan.nextInt(); System.out.println(\月历如下\
CalenderModelA testBegin = new CalenderModelA(); testBegin.show(year, month);
第三章 面向对象编程
一、选择题
1-5 CABDD 2-10 DCCBC 11-12 CC
二、填空题
1.Package mypackage ; 2.final 3.Object
4.package import class
5.c
三、程序设计题
2、按下列要求编写程序： ① double ②
创建TeacherTest类
要求：在TeacherTest类中创建Teacher的对象；为该对象的属性（姓创建Teacher类
要求：Teacher类要描述姓名、年龄、薪水，类型分别为String、int、
名、性别、年龄）赋值；将该对象的属性（姓名、性别、年龄）输出； ③ ④
为Teacher类添加一个方法，用于在教师原有薪水的基础上增加5000； 修改TeacherTest类，增加对教师增加薪水方法的调用，并将增加后的薪
水值输出。 Teacher.java： public class Teacher {
public String name; public int age; public double salary; public String getName() {
return name;
}
}
public void setName(String name) { }
public int getAge() { }
public void setAge(int age) { }
public double getSalary() { }
public void setSalary(double salary) { }
public Teacher(){ }
public Teacher(String name,int age,double salary){ }
public void addSalary(){ }
this.salary=this.salary+5000; this.name=name; this.age=age; this.salary=salary; this.salary = salary; return salary; this.age = age; return age; this.name = name;
TeacherTest.java： public class TeacherTest {
public static void main(String[] args) {
Teacher teacher=new Teacher();
