Obj作爲參數，然後返回其他函數？

Question

僞代碼：

function A() 
{ 
    Obj objA = new... // 
    function B(objA) 
} 

function B(obj test) 
{ 
    return test; 
} 

    function C() 
{ 
    Obj objC = use function B() to get the objA 
    // do whatever with objC 
} 

我知道這是不是一個好辦法，但如何通過將對象從函數A到函數C？未做一個全局對象... 這是由Java代碼應該...

是不是你基本上只是想存儲在該對象的類別？

Class Example { 
    private SomeObject obj; 

    public void A() { 
    obj = new Obj(); 
    } 

    public SomeObject B(SomeObject obj) { 
    this.obj = obj; // save the passed instance into the object 
    return obj; 
    } 

    public void C() { 
    obj.callSomeFunction(); // it'll still exist here, as long as you called A() before C() 
    } 
}
