java - 从数组java中删除对象

Question

我的练习题说“这个方法返回一个包含指定元素的数组

 // array of Objects, with the Object at the specified index removed.

    // the returned array should be smaller by one and have all elements

    // in the same relative location to each other. YOU MAY NOT USE

    // A LIST :)

Object[] remove(int index, Object[] arr){"

到目前为止，我已经想出了这个方法，但我并不完全确定它是否有效。你们能否看一下并给我一些有关如何修复它的反馈，以便我可以正确地执行此“删除”操作。

public static remove(int index, Object[] arr){
int counter = 0;
int temp = 2;
int[] arr = {1, 2, 3, 4};
int[] second = new int[arr.length-1];

    for(int i=0; i< arr.length;i++){
        if(i != temp){
            second[counter] = arr[i];
            counter ++;

        }
        //return second;
    }

Answer 1

public static Object[] remove(int index, Object[] array) {
    Object[] newArray = new Object[array.length - 1];
    for (int i = 0; i < array.length; i++) {
        if (index > i) {
            newArray[i] = array[i];
        } else if(index < i) {
            newArray[i - 1] = array[i];
        }
    }
    return newArray;
}
