我正在尝试添加通过方法调用从数组中删除项的功能，但遇到了标题中发布的问题。
说明如下：
为arrayintlist类编写一个名为remove的新方法，该方法采用整数索引并删除给定索引处的值，然后将后续值向左移动。例如，如果名为list的变量存储以下值：

[3, 19, 42, 7, -3, 4]

进行此方法调用后：
“列表。删除（1）；”将从数组中删除3（不是这不特定于数组的第一个值）
我试图实现这样的目标：

public void remove(int index) {
        int target = index;
        int[] elementDataCopy = new int[size];
        size = elementData.length;
        if (index < 0 || index >= size) {
            throw new IllegalArgumentException("invalid index");
        }
        //loop through each value until the index given is == to loop value
        //create a copy of elementData where length is one less and value at 
        //index given is not present
        //each time something is removed, the tracked values decrease by one
        size--;
        for(int i = 0; i < elementData.length + 2; i++){
            if (elementData[i] == target){
                continue;
            }else{
                elementDataCopy[i] = elementData[i];
            }
        }
    }
``
but get this error:

失败：索引12超出长度12的界限

with the numbers differing depending on what input is.
note that elementData is an array of ints and index is an int that is pointing at a point in said array
all help is appreciated, pretty sure this is something basic
