请补全预设代码中判断回文数的方法，若输入的五位数字是回文是则返回true，否则返回false。回文数即个位与万位相同，十位与千位相同的数字。如：12321、89898

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner console = new Scanner(System.in);
        Main main = new Main();
        int number = console.nextInt();
        System.out.println(main.palindromeNumber(number));
    }

    public Boolean palindromeNumber(int number) {

        //write your code here......
        
        return number%10==number/10000 && number/10%10==number/1000%10;

    }
}
