面向对象程序设计（Java）实验报告福建工程学院软件学院实验报告2016 2017 学年度第 一 学期 任课教师： 陈丽晖课程名称面向对象程序设计（Java）班级物联网(本)1401座号31姓名谢学伟实验题目实验时间实验开始日期：2016.09.20实验提交日期：实验目的、要求1. 如图所示，编写类Point。Point包含两个成员变量x、y分别表示x和y坐标。movePoint方法实现点的位置的移动(dx,dy表示相对位移)。getDistance求该点与另外一个点的距离。编写用户程序TestPoint，创建两个Point对象p1,p2，分别调用movePoint()方法后，打印p1和p2的坐标，然后求p1和p2之间的距离2.如图所示，编写圆类Circle。area方法求圆的面积，perimeter求圆的周长。编写用户程序TestCircle，创建一个圆，求圆的面积和周长并打印出来。3.编写矩形类Rectangle。area方法求矩形的面积，perimeter求矩形的周长。编写用户程序TestRectangle，创建一个矩形，求该矩形的面积和周长并打印。4.如图所示，写一个成绩类Score，包含英语、数学、语文、综合四科。getTotalScore求总分，average求平均分。编写用户程序TestScore，创建一成绩对象，并对各科赋值。然后求总分和平均分。5.编写学生类Student，包含学号，姓名，是否特殊考生和成绩等属性，成绩利用上题编写的Score类。特殊考生总成绩加10分。编写用户程序TestStudent，创建学生，修改其成绩，求其总分并打印，调用speak方法来理解重载。实验步骤与内容（备注截图）1. public class Point private double x;private double y;private double newX;private double newY;public Point() / TODO Auto-generated constructor stubpublic Point(double x, double y) this.x = x;this.y = y;public double getX() return x;public void setX(double x) this.x = x;public double getY() return y;public void setY(double y) this.y = y;public void movePoint(double dx,double dy)this.newX=x+dx;this.newY=y+dy;public double getDinstance()double dinstance;dinstance=Math.sqrt(Math.pow(Math.abs(x-newX),2)+Math.pow(Math.abs(y-newY),2);return dinstance;public class PointTest public static void main(String args) Scanner scanner=new Scanner(System.in);Point point=new Point();while (true) System.out.println(请输入原始点位置);System.out.println(原始点X坐标);double x = scanner.nextDouble();System.out.println(原始点y坐标);double y = scanner.nextDouble();System.out.println(请输入移动的X值);double moveX=scanner.nextDouble();System.out.println(请输入移动的Y值);double moveY=scanner.nextDouble();point.movePoint(moveX, moveY);System.out.println(两点之间的距离为：+point.getDinstance();2. public class Circle private double r;private double area;public Circle() public double getR() return r;public void setR(double r) this.r = r;public double getArea() return area;public void setArea(double area) this.area = area;public double perimeter(double r)double area=Math.PI*r*r;return area;public double zhouChang(double r)double zhouChang;return zhouChang=Math.PI*r*2;public class CircleTest public static void main(String args) Circle circle=new Circle();Scanner scanner=new Scanner(System.in);while (true) System.out.println(请输入圆形的半径);double r=scanner.nextDouble();System.out.println(圆形的面积是：+circle.perimeter(r);System.out.println(圆形的周长是：+circle.zhouChang(r);3. public class Rectangle private double length;private double width;public Rectangle() / TODO Auto-generated constructor stubpublic double getLength() return length;public void setLength(double length) this.length = length;public double getWidth() return width;public void setWidth(double width) this.width = width;public double area()return length*width;public double perimeter()return length*2+width*2;public class RectangleTest public static void main(String args) Scanner scanner=new Scanner(System.in);Rectangle rectangle=new Rectangle();while (true) System.out.println(请输入矩形的长：);double length=scanner.nextDouble();System.out.println(请输入矩形的宽：);double width=scanner.nextDouble();rectangle.setLength(length);rectangle.setWidth(width);System.out.println(矩形的面积是：+rectangle.area();System.out.println(矩形的周长是：+rectangle.perimeter();4.public class Score private double Chinese;private double Math;private double English;private double Zonghe;public Score() public Score(double chinese, double math, double english, double zonghe) Chinese = chinese;Math = math;English = english;Zonghe = zonghe;public double getChinese() return Chinese;public void setChinese(double chinese) Chinese = chinese;public double getMath() return Math;public void setMath(double math) Math = math;public double getEnglish() return English;public void setEnglish(double english) English = english;public double getZonghe() return Zonghe;public void setZonghe(double zonghe) Zonghe = zonghe;public double getTotalScore()double totle=Chinese+English+Math+Zonghe;return totle;public double average()double average=(Chinese+English+Math+Zonghe)/4;return average;public class ScoreTest public static void main(String args) Scanner scanner=new Scanner(System.in);System.out.println(请输入语文成绩：);double Chinese=scanner.nextDouble();System.out.println(请输入数学成绩：);double Math=scanner.nextDouble();System.out.println(请输入英语成绩);double English=scanner.nextDouble();System.out.println(请输入综合成绩：);double zonghe=scanner.nextDouble();Score score=new Score();score.setChinese(Chinese);score.setEnglish(English);score.setMath(Math);score.setZonghe(zonghe);System.out.println(总成绩：+score.getTotalScore();System.out.println(平均分：+score.average();5. public class Student private String id;private String name;private boolean special=false;private Score score;public Student() / TODO Auto-generated constructor stubpublic Student(String id, String name, boolean special, Score score) this.id = id;
