outerInstance.new InnerClass[] { };

[Garrett Smith]

I want to declare an array of type InnerClass but I don't know how.

  
public class OuterClass {
    class InnerClass {
    }
    public static void main(String[] args) {
        OuterClass oc = new OuterClass();
        OuterClass.InnerClass[] inners = [B]oc.[/B]new InnerClass[] {
            oc.new InnerClass(), oc.new InnerClass() 
        };
    }
}

The program will compile if I use:

OuterClass oc = new OuterClass();
        OuterClass.InnerClass[] inners = new InnerClass[] {

However, I will not be able to instatiate a new InnerClass[] from somewhere outside class OuterClass. I can get away with that here because InnerClass is in class scope.

This will not compile:

[B]oc.[/B]new InnerClass[] {

OK. I think I figured it out.
With a array declaration, I specify the type, so OuterClass.InnerClass[].

 public class OuterClass {
    static volatile int innerInstanceCount = 0;
    
    class InnerClass {
    
        volatile int _id = innerInstanceCount;
        
        public InnerClass() {
            _id = innerInstanceCount++;
        }
        
        public String toString() {
            return "InnerClass " + _id;
        }
    }
    public static void main(String[] args) {
        OuterClass oc = new OuterClass();
        OuterClass.InnerClass[] inners = new OuterClass.InnerClass[] {
            oc.new InnerClass(), oc.new InnerClass() 
        };
        
        System.out.println(java.util.Arrays.asList(inners));
    }
}
