java实现风车旋转,为嘛我的画出来时一个圆在旋转

画之前加上g.clearRect(0, 0, getWidth(), getHeight());

不然你上一次画的还灶搭会呈现出来

这样呢,就会闪烁,需要使用双缓冲来解决了。厅亮

需要扮辩宽请追问。

请问如何用Java编写一个汽车类Car

public class Car {

private String color;//颜色

private int door;//车门数量

private float speed;//车速

public Car(){

this.color = "红色";

this.door = 3;

this.speed = 110;

}

public Car(String color, int door, float speed) {

this.color = color;

this.door = door;

this.speed = speed;

}

public void start(){

//汽车启动。输出汽车已启动,并输出汽车的各个属性

System.out.println("汽车已启动,汽车颜色为"+color+",车门数为"+door+",车速为"+speed);

}

public void speedUp(float speed){

//加速

System.out.println("汽车加速到"+speed+"km/h");

}

public void shutDown(float speed){

//减速

System.out.println("汽车减速到"+speed+"岁如凳km/h");

}

public void brake(){

//刹车

System.out.println("已刹车");

}

}

public class Test {

public static void main(String[] args){

Car car = new Car();

car.start();

car.speedUp(100);

car.shutDown(60);

car.brake();

Car car1 = new Car("乎旅白色",4,20.2F);

car1.start();

car1.speedUp(100);

car1.shutDown(60);

car1.brake();

}

}

用JAVA编写一个程序,要求如下:

实现代码如下:

Student类:

public class Student {

private String name;

private String sex;

private int age;

private double chinese;

private double math;

private double english;

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getSex() {

return sex;

}

public void setSex(String sex) {

this.sex = sex;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

public double getChinese() {

return chinese;

}

public void setChinese(double chinese) {

this.chinese = chinese;

}

public double getMath() {

return math;

}

public void setMath(double math) {

this.math = math;

}

public double getEnglish() {

return english;

}

public void setEnglish(double english) {

this.english = english;

}

}

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

StudentTest类:腊誉(测试类)

import java.util.Scanner;

public class StudentTest {

public static void main(String[] args) {

Student student = new Student();

Scanner sc = new Scanner(System.in);

System.out.println("请输入姓名:");

student.setName(sc.next());

System.out.println("请输入性别:");

student.setSex(sc.next());

System.out.println("请输入年龄:");

student.setAge(sc.nextInt());

System.out.println("请滚衫输入语文成绩、数学成绩、英语成绩:");

student.setChinese(sc.nextDouble());

student.setMath(sc.nextDouble());

student.setEnglish(sc.nextDouble());

Double count = student.getChinese()+ student.getMath()+student.getEnglish();

System.out.println("姓名:"+student.getName()+" 性别:"+student.getSex()+" 年龄:"+student.getAge());

System.out.println("总分:"+count+" 平均分:"+count/3);

}

}

运行结果为大局腔:
