如何将字符串插入到字符串数组中的特定索引中，并在之后移动字符串？

public class StringArrayInsertion {
    public static void main(String[] args) {
        String[] originalArray = {"apple", "banana", "cherry", "date"};
        String insertString = "grape";
        int insertIndex = 2;

        // 创建新的字符串数组
        String[] newArray = new String[originalArray.length + 1];

        // 复制特定索引之前的字符串
        for (int i = 0; i < insertIndex; i++) {
            newArray[i] = originalArray[i];
        }

        // 插入要插入的字符串
        newArray[insertIndex] = insertString;

        // 复制特定索引之后的字符串
        for (int i = insertIndex; i < originalArray.length; i++) {
            newArray[i + 1] = originalArray[i];
        }

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

        // 打印结果
        for (String str : originalArray) {
            System.out.println(str);
        }
    }
}
