方法一：使用StringBuilder

import java.util.Scanner;public class StrReversal { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); String str = scanner.nextLine(); System.out.println(new StringBuilder(str).reverse()); }}

方法二：使用循環(huán)

import java.util.Scanner;public class StrReversal { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); String str = scanner.nextLine(); char[] chars = str.toCharArray(); String reverse = ''; for (int i = chars.length - 1;i>=0;i--){ reverse += chars[i]; } System.out.println(reverse); }}

方法三：考慮到String不可變，使用StringBuilder

import java.util.Scanner;public class StrReversal { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); String str = scanner.nextLine(); char[] chars = str.toCharArray(); StringBuilder reverse = new StringBuilder(); for (int i = chars.length - 1;i>=0;i--){ reverse.append(chars[i]); } System.out.println(reverse); }}

以上就是JAVA字符串反轉(zhuǎn)的三種方法的詳細(xì)內(nèi)容，更多關(guān)于JAVA字符串反轉(zhuǎn)的資料請關(guān)注好吧啦網(wǎng)其它相關(guān)文章！
