编写一个截取字符串的函数，输入为一个字符串和字节数，输出为按字节截取的字符串。 但是要保证汉字...

public class Exercise {

	public static void main(String[] args) {
		print("我as我hias暗示", 6);
	}

	private static void print(String s, int count) {
		byte[] arr = s.getBytes();// 获得字节数组
		count = isCnBegin(arr, count - 1) ? count - 1 :count;
		System.out.println(new String(arr, 0, count));
	}

	private static boolean isCnBegin(byte[] arr, int index) {
		// TODO Auto-generated method stub
		boolean b = false;
		for (int i = 0; i <= index; i++)
			b = arr[i] < 0 && !b;
		return b;
	}
}
