秋名山代码实操题目

主类

package com.chuxing.a;

public class dome1 {
	/*
	 * 这里会出现异常，Thread.sleep(500);
	 * 这个代码是在car类内，但是调用了就会出现异常，所以需要在使用的地方处理异常。
	 */
	public static void main(String []args) throws InterruptedException{
	Car car=new Car("奔驰","黑色",4);
	Factory factory=new Factory("秋名山汽修店","秋名山山脚下豆腐店旁边","133*******");
	while(car.getSpeed()<=600){
		car.race();
		if(car.getSpeed()>300){
		/*
		 * 这里设置的速度超过阈值就会爆胎
		 * 需要去修理
		 * 这里设置的是无限循环的代码。
		 */
		car.setWheelcount(3);
		car.race();
		factory.repair(car);
		}
	}
}
}

汽车类

package com.chuxing.a;
public class Car {

	private int wheelcount ;
	private int speed = 0 ;

		speed=speed+50;
		/*
		 * 这里就是异常Thread.sleep(500);
		 * 需要ctrl+1选择第一项
		 * 我这里设置了一个变量速度speed
		 * 主类内检测速度值超过阈值之后就会爆胎
		 */
