Java 数组和泛型：Java 相当于 C# IEnumerableT

java
int[] numbers = new int[5];

java
numbers[0] = 10;

java
public class MyList {
    private T[] elements;
    private int size;
    public MyList() {
        elements = (T[]) new Object[10];
        size = 0;
    }
    public void add(T element) {
        elements[size] = element;
        size++;
    }
    public T get(int index) {
        return elements[index];
    }
}

java
public class Main {
    public static void main(String[] args) {
        MyList myList = new MyList<>();
        myList.add("Hello");
        myList.add("World");
        
        for (int i = 0; i < myList.getSize(); i++) {
            System.out.println(myList.get(i));
        }
    }
}
