为交管局设计一个违规管理系统；要求记录违规车辆，驾驶员，处理交警信息； 分析： 1、对象：车辆、车辆型号、驾驶证、驾驶证分、车主姓名、罚款、驾驶证状态、扣分、违规 2、抽类： TrafficControl交通管理类： 闯红灯扣分、罚款；乱停车扣分、罚款；超速扣分、罚款；未系安全带扣分、罚款；（后期可增加） CarInformation车辆信息类： 属性：车辆型号、驾驶证、驾驶证分、车主姓名、罚款、驾驶证状态（车牌号待加入）；  方法：查询车辆信息状态，判断驾驶证状态 interface接口TrafficRegulations违章：闯红灯，超速，乱停，未系安全带（。。。。可继续增加） package com.lovo.violationManagementSystem.bean;/**  * 定义一个标准：违章  * @author 侯熙  * @version 1.0  * @since jdk1.8.0_25  */public interface TrafficRegulations {	/**	 * 闯红灯	 */	public void runRedLights();	/**	 * 超速	 * @param speed 当前速度	 * @param limitedSpeed 限定速度	 */	public void overSpeed(double speed,double limitedSpeed);	/**	 * 违章停车	 */	public void illegalParking();	/**	 * 未系安全带	 */	public void fastenSeatBelt();}package com.lovo.violationManagementSystem.bean;/**  * 交通管理  * @author 侯熙  * @version 1.0  * @since jdk1.8.0_25  */public class TrafficControl extends CarInformation implements TrafficRegulations{	/**	 * 闯红灯扣分	 */	static final int RUN_RED_LIGHTS_SCORE = -6;	/**	 * 闯红灯罚款	 */	static final int RUN_RED_LIGHTS_MONEY = -200;	/**	 * 违规停车罚款	 */	static final int ILLEGAL_PARKING_MONEY = -200;	/**	 * 未系安全带扣分	 */	static final int FASTE_NSEAT_BELT_SCORE = -2;	/**	 * 未系安全带罚款	 */	static final int FASTE_NSEAT_BELT_MONEY = -200;	private int overSpeedScore;//超速扣分	private int overSpeedMoney;//超速罚款	/**	 * 构造方法	 * @param carName 车辆型号	 * @param drivingLicence 驾驶证信息	 * @param driver 驾驶员姓名	 */	public TrafficControl(String carName, int drivingLicence, String driver) {		super(carName, drivingLicence, driver);		// TODO Auto-generated constructor stub	}	@Override	public void runRedLights() {		// TODO Auto-generated method stub		this.score += RUN_RED_LIGHTS_SCORE;		this.money += RUN_RED_LIGHTS_MONEY;	}	@Override	public void overSpeed(double speed,double limitedSpeed) {		// TODO Auto-generated method stub		if (speed > limitedSpeed*(1+0.5)) {			this.overSpeedScore = -12;			this.overSpeedMoney = -2000;		}else if (speed > limitedSpeed*(1+0.2)) {			this.overSpeedScore = -6;			this.overSpeedMoney = -200;		}else if (speed > limitedSpeed) {			this.overSpeedScore = -3;			this.overSpeedMoney = -200;		}else{			this.overSpeedScore = 0;			this.overSpeedMoney = 0;		}		this.score += this.overSpeedScore;		this.money += this.overSpeedMoney;	}	@Override	public void illegalParking() {		// TODO Auto-generated method stub		this.money += ILLEGAL_PARKING_MONEY;	}	@Override	public void fastenSeatBelt() {		// TODO Auto-generated method stub		this.score += FASTE_NSEAT_BELT_SCORE;		this.money += FASTE_NSEAT_BELT_MONEY;		}}package com.lovo.violationManagementSystem.bean; /**  * 车辆信息  * @author 侯熙  * @version 1.0  * @since jdk1.8.0_25  */ public class CarInformation {
