如何在数组中找到给定字符串的“字符串号”？

public class StringFinder {
    public static int findStringIndex(String[] array, String target) {
        for (int i = 0; i < array.length; i++) {
            if (array[i].equals(target)) {
                return i; // 返回匹配的字符串号
            }
        }
        return -1; // 未找到匹配的字符串
    }

    public static void main(String[] args) {
        String[] array = {"apple", "banana", "orange", "grape"};
        String target = "orange";
        int stringIndex = findStringIndex(array, target);
        if (stringIndex != -1) {
            System.out.println("找到了目标字符串，字符串号为：" + stringIndex);
        } else {
            System.out.println("未找到目标字符串");
        }
    }
}
