		String ss = "1432去fad阿萨德撒sgi";
		byte[] b = ss.getBytes("GBK");
		if(b.length>ss.length()) {
			System.out.println("有汉字，个数为"+(b.length-ss.length()));
		}
		
		System.out.println("===================================");
		//字符串中字符排序
		char[] cc = ss.toCharArray();
		System.out.println("排序前字符串："+ss);
		Arrays.sort(cc);
		ss = new String(cc);
		System.out.println("排序后字符串："+ss);
