判断是否为回文

package palindrome;import java.util.Scanner;//判断是否为回文——判断用户输入的字符串是否为回文。回文是指正反拼写形式都是一样的词，譬如“racecar”。public class Palindrome {    public static void main(String[] args) {        System.out.print("请输入一个字符串(Please input a string):");        Scanner scanner = new Scanner(System.in);        String line = scanner.nextLine();        line = line.toLowerCase();        for (int i=0;i<line.length()/2;i++){            if (String.valueOf(line.charAt(i)).equals(String.valueOf(line.charAt(line.length()-i-1)))){            }else {                System.out.println("这个字符串不是回文(This string is not palindrome)");                continue;            }        }        System.out.println("这个字符串是回文(This string is palindrome)");    }}
