将一个对象数据移动到另一个

Question

So basically, I want to move an object data to another object (Queue jockeying).

let's say I have

int counter1,counter2

and I have methods

void enQueue1(object data)
void enQueue2(object data)
void deQueue1()
void deQueue2()

And, for example, I do this

obj1.enQueue1("data 1")
obj2.enQueue2("data 2")
obj2.enQueue2("data 3")
obj2.enQueue2("data 4")

What I wanna do is when the difference between counter1 and counter2 is >1, I want to move the data from larger counter so I have a balanced counter1 and counter2

So, how can I move the "data 4" from obj2 to obj1?

I wrote a pseudocode that look like this:

if (counter1 - counter2) == -2
obj2.deQueue2
obj1.enQueue(obj2.enQueue("data 4"))

How can I achieve this in java code? Your help is much appreciated

Thanks!

Answer 1

Have your deQueue methods return the last inserted object, and remove it from the current class as you probably already do :

Object deQueue()

Then

obj1.enQueue(obj2.deQueue());
