如何从给定的值中找到java数组中字符串的索引？

public class ArraySearch {
    public static int findIndex(String[] array, String target) {
        for (int i = 0; i < array.length; i++) {
            if (array[i].equals(target)) {
                return i;
            }
        }
        return -1; // 如果未找到目标字符串，返回-1
    }

    public static void main(String[] args) {
        String[] array = {"apple", "banana", "orange", "grape"};
        String target = "orange";
        int index = findIndex(array, target);
        if (index != -1) {
            System.out.println("目标字符串的索引为：" + index);
        } else {
            System.out.println("未找到目标字符串");
        }
    }
}
