判断number是回文数的条件代码是什么 用java的

char[] ch = number.toString().toCharArray();
int i = 0;
for(; i < number.toString().length/2; i ++) {
if (!ch[i].toString().equals(ch[number.toString().length-1-i].toString())
break;
}
if (i == number.toString().length/2) {
System.out.println(number + "是回文数");
} else {
System.out.println(number + "不是回文数");
}
