Q2: java难题，急，求代码？
接口和类全在一个包下，如果不在一个包下记得import调用，show的重写你根据需要自己改

}

public class Bus implements ShouFei{
String airConditioning;
double money;

this.airConditioning = airConditioning;

@Override
public void fuFei(double mileage) {
if(airConditioning.equals("空调")){
money = 2;
}else{
money = 1;
}
}
@Override
public void show() {
System.out.println("公交车，"+airConditioning+",费用："+money);
}
}

Q3: java 是怎么收费，版权收费？
java是源代码，不需要收费的。自己开发的项目卖给别人，肯定是要收费啊(从别人的口袋里拿到自己的口袋里)，eclipse软件是不收费的，myEclipse软件是需要买注册码，但现在网上一大堆破解码，这个你可以直接拿来用，所以你也就可以不花钱用myEclipse了
Q4: ?求助java编程问题： 某城市用水实行阶梯计费，规则如下：对于生活用
