Java 中的自定义迭代器

import java.util.Iterator; // Iterator Import
class CustomList<Type> implements Iterable<Type> {
  private Type[] arrayList;
  private int Size;
  public CustomList(Type[] newArray) { // Constructor Which Accepts Array...
    this.arrayList = newArray;
    this.Size = arrayList.length;
  }
  @Override
  public Iterator<Type> iterator() {
    // OverRiding Default List Iterator //
    Iterator<Type> it = new Iterator<Type>() {
      private int currentIndex = 0;
      @Override
      public boolean hasNext() {
        // OverRiding Default hasNext  Method//
        return currentIndex < Size && arrayList[currentIndex] != null;
      }
      @Override
      public Type next() {
        // OverRiding Default next  Method//
        return arrayList[currentIndex++];
      }
      @Override
      public void remove() {
        // OverRiding Default Remove  Method.
        throw new UnsupportedOperationException();
      }
    };
    return it;
  }
}
public class Main {
  public static void main(String args[]) {
    String[] data = new String[] {"Tim Cook", "Mark Zuckerberg", "Elon Musk", "Jeff Bezos"};
    CustomList<String> Listt = new CustomList<String>(data);
    // creating a CustomList Object Which OverRides.
    // The Iterator and Use The Custom Iterator Which is Defined in The Code.
    Iterator temp = Listt.iterator(); // getting Custom iterator from List.
    while (temp.hasNext()) { // custom hasNext() Method
      String value = temp.next().toString(); // Custom Method Return The Current Index
      System.out.print(value + ", ");
    }
  }
}
