是否可以在不同的对象中使用单个输入？

Question

The both codes below are from different class files.

I'm trying to use the input from spinWheels for pull.

Is that possible?

public int spinWheels(int betAmt)
{
    String[] aWheel = new String[5];
    Scanner kb = new Scanner(System.in);
    betAmt = kb.nextInt();
}


public void pull(int bet)
{
    betAmt = bet;
    totalcoins = totalcoins - bet;
}

Answer 1

You mean like this?

int x = 0;
spinWheels(x);
pull(x);

Answer 2

It is possible but there are several things that you must do first. Say you have a class A:

class A{
    public int spinWheels(int betAmt)
    {
        String[] aWheel = new String[5];
        Scanner kb = new Scanner(System.in);
        return kb.nextInt(); //I assume you need this value later
        //you must return an int here
     }
}

and you have a second class B:

 class B{
     public void pull()
     {
       //you need a reference to an Object of type A
       A a = new A();       
       bet = a.spinWheels();
       totalcoins = totalcoins - bet;
     }
 }

Of course the above code is very simplistic, without knowing what you want to achieve it is not possible to say more.

Answer 3

You could just use

public int spinWheels()
{
    String[] aWheel = new String[5];
    Scanner kb = new Scanner(kb.nextInt());
    ...
}

I don't understand why you'd want to pass betAmt as an argument if you're going to run it over anyway...
