判断对称字符串或对称数（Java实现）

判断一个数是否为对称数，如：123321，2332，abccba等等。Java代码如下：

public class SymmetryNumber {

	public static boolean isSymmetryNumber(long n) {
		String str = String.valueOf(n);
		return isSymmetString(str);
	}
	public static boolean isSymmetString(String str) {
		int count = str.length();
		String str1 = str.substring(0, count / 2);
		String str2 = str.substring(((count & 0x1) == 0)
				? (count / 2)
				: (count / 2 + 1));
		StringBuffer strBuf = new StringBuffer(str2);
		str2 = strBuf.reverse().toString();
		return str1.equals(str2);
	}

	public static void main(String[] args) {
		for (long i = 10000; i < 20000L; i++) {
			System.out.print(i);
			System.out.println(":\t" + SymmetryNumber.isSymmetryNumber(i));
		}

	}
}
