在不同的类中创建内部类对象数组

Question

请考虑以下嵌套类。

class Outerclass { 

    class innerclass { 

    } 

} 

class util { 

//how to declare an array of innerclass objects here? 
} 

Answer 1

您可以声明这样一个innerclass对象的数组。

class util { 
    Outerclass.innerclass[] inner = new Outerclass.innerclass[10]; 
} 

并以实例化他们，你可以做这样的事情的util类中。

void test() { 
    Outerclass outer = new Outerclass(); 
    inner[0] = outer.new innerclass(); 
} 

Answer 2

OuterClass outerObject = new OuterClass(); 
OuterClass.InnerClass innerArray[] = new OuterClass.InnerClass[3]; 
// Creating Objects of Inner Class 
OuterClass.InnerClass innerObject1 = outerObject.new InnerClass(); 
OuterClass.InnerClass innerObject2 = outerObject.new InnerClass(); 
OuterClass.InnerClass innerObject3 = outerObject.new InnerClass(); 
// Adding the Objects to the Array 
innerArray[0] = innerObject1; 
innerArray[0] = innerObject2; 
innerArray[0] = innerObject3;
