 想在这个程序下做如下修改:给Elevator类添加一个表示电梯名的实例变量,可以将他命名为myName,此实例变量是用private还是public?编写一个构造函数,当你用new关键字创建一个Elevator对象并赋予一个变量时,通过构造函数来为此变量设置值,当使用new关键字时,调整对构造函数的调用方法,将Elevator的名字作为一个参数(花括号之间,而不是在new Elevator()之间插入),写成new Elevator("ElevatorA")

Elevator每完成一次运输它必须打印出发和到达楼层名  不是打印:Departing floor: 2 Traveling to floor 24
 应该打印:ElevatorA:Departing floor: 2 Traveling to floor 24 其中ElevatorA是myName中Elevator的名字

没有哪位高人指点一下吗 急啊!!!
