How to delete a specific object in a Java array?

To remove a specific object from an array in Java, you can follow the steps below:

1. Iterate through the array to find the index position of the object that needs to be deleted.
2. Create a new array with a length one less than the original array.
3. Copy the elements from the original array to a new array, excluding the ones that need to be deleted.
4. Assign the new array to the original array.

Here is an example code:

public class Main {
    public static void main(String[] args) {
        // 原数组
        String[] array = {"A", "B", "C", "D", "E"};

        // 需要删除的对象
        String target = "C";

        // 查找需要删除的对象的索引位置
        int targetIndex = -1;
        for (int i = 0; i < array.length; i++) {
            if (array[i].equals(target)) {
                targetIndex = i;
                break;
            }
        }

        // 如果找到了需要删除的对象
        if (targetIndex != -1) {
            // 创建新数组
            String[] newArray = new String[array.length - 1];

            // 将原数组中除需要删除的对象以外的元素复制到新数组中
            int j = 0;
            for (int i = 0; i < array.length; i++) {
                if (i != targetIndex) {
                    newArray[j] = array[i];
                    j++;
                }
            }

            // 将新数组赋值给原数组
            array = newArray;
        }

        // 输出删除指定对象后的数组
        for (String element : array) {
            System.out.println(element);
        }
    }
}

In this example code, the original array is {“A”, “B”, “C”, “D”, “E”} and the object to be deleted is “C”. The output of running the code is:

A
B
D
E
