Question

public class DanamicArray9_数组{

    private int size;
    private int capacity;
    private int[] arr = new int[capacity];
    
    
    public void addlast(int element) {
        arr[size]=element;
        size++;
    }
    
    public void add(int index,int element) {
    if(index>=0&&index<size){
        System.arraycopy(arr, index, arr, index+1, size-index);
        arr[size]=element;
        size++;
        }
    }
    }

public class DanamicArray9_数组测试 {
    
    @Test
    public void test1() {
        DanamicArray9_数组 DanamicArray9  = new     DanamicArray9_数组();
        DanamicArray9.addlast(1);
        DanamicArray9.addlast(2);
        DanamicArray9.addlast(3);

有帮助的话 采纳一下

改成这样

System.out.println(DanamicArray9.get(i));
