由Java泛型看Kotlin的泛型

class MyList{

    private int size;
    private Object[] elements = new Object[10];
    
    public void add(Object item) {
    	elements[size++]=item;
    }
    
    public Object get(int index) {
    	return elements[index];
    }
}

MyList myList = new MyList();
myList.add("A");
myList.add(1);
System.out.println(myList.get(0));
System.out.println((String)myList.get(1));
