java随机生成汉字

生成多个汉字的话加个循环执行以下代码即可

    //随机生成汉字
    private static char getRandomChar() {
        String str = "";
        int hightPos; //
        int lowPos;

        Random random = new Random();

        hightPos = (176 + Math.abs(random.nextInt(39)));
        lowPos = (161 + Math.abs(random.nextInt(93)));

        byte[] b = new byte[2];
        b[0] = (Integer.valueOf(hightPos)).bytevalue();
        b[1] = (Integer.valueOf(lowPos)).bytevalue();

        try {
            str = new String(b, "GBK");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
            System.out.println("错误");
        }

        return str.charAt(0);
    }
