java语言判断一个数字是否为回文数字

import java.util.Scanner;

public class test04 {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
          Scanner scanner = new Scanner(System.in);
          System.out.println("输入一个数:");
          int x = scanner.nextInt();
          int a,b,c;      
              int i=0;
        
              a=x/100;
              b=x%10;
              if(a==b){
                  System.out.println("是回文数");
              }else{
                  System.out.println("不是回文数");
                  
              }
            
          
          
          
    }

}
