JAVA按字节截取UTF-8编码的字符串(其他编码也适用)

代码如下,有更好的意见请留言.

	public static void main(String[] args) throws Exception {
		String encode = "UTF-8";
		// 截取10字节,不出错
		int sublen = 10;
		// UTF-8字节
		String srcStr = "出错出hh错出错hello1出错";
		// 先转化成char
		char[] srcStrChars = srcStr.toCharArray();
		int cnt = 0;
		Charset cs = Charset.forName(encode);
		CharBuffer cb = CharBuffer.allocate(1);
		ByteBuffer resultBuff = ByteBuffer.allocate(sublen);
		for (int i = 0; i < srcStrChars.length; i++) {
			char c = srcStrChars[i];
			cb.put(c);
			cb.flip();
			ByteBuffer bb = cs.encode(cb);
			cnt += bb.array().length;
			if(cnt > sublen){
				break;
			}
			resultBuff.put(bb);
			cb.clear();
		}
		String result = new String(resultBuff.array(), encode);
		System.out.println(result);
	}
