java习题定义一个交通工具类Vehicle，包含属性（speed，name，color）和方法（start，stop，run）定义一个飞行器子类Aircraft继承自Vehicle类。然后从Aircraft类派生两个子类，航天飞机（SpaceShuttle）和喷气式飞机（Jet），谢谢
1、Vehicle类所具有的属性题目没有给定数据类型，自主选择定义属性的数据类型。代码如下
public class Vehicle{private double speed;//速度
private String name;//名字
private String color;//颜色
public double getSpeed() {
return speed;
}
public void setSpeed(double speed) {
this.speed = speed;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getColor() {
return color;
}
public void setColor(String color) {
this.color = color;
}
//start方法
public void start()
{
System.out.println("汽车,"+this.name+this.color+"启动。");
}
//stop方法
public void stop( )
{
System.out.println("汽车,"+this.name+this.color+"停止。");
}
//run方法
public void run( )
{
System.out.println("汽车,"+this.name+"行驶,速度 "+this.speed+"km/h");
}
public static void main(String[] args) {
//主方法，执行需要的操作
Vehicle v =new Vehicle();
v.setName("奔驰");
v.setColor("红色");
v.setSpeed(120);
v.start();
v.run();
v.stop();
}
}
2、在主方法程序中生成Vehicle的对象，通过set方法给对象赋值，运行效果
