java中将字符串反转

以下是两种Java中将字符串反转的方法：

1.通过字符数组实现反转：

public static String reverseCharArray(String s) {
    char[] array = s.toCharArray();
    String reverse = "";
    for (int i = array.length - 1; i >= 0; i--) {
        reverse += array[i];
    }
    return reverse;
}

2.通过递归实现反转：

    int length = s.length();
    if (length <= 1) {
        return s;
    }
    String left = s.substring(0, length / 2);
    String right = s.substring(length / 2, length);
    String afterReverse = reverseRecursive(right) + reverseRecursive(left);
    return afterReverse;
}
