【JAVA】java关于byte string

 @Test
    public void test1() throws UnsupportedEncodingException {

        // 三者等价
//        byte [] a = {00010110,  01010010,  10111000};
//        byte [] a = {0x16,      0x52,      0xB8};
//        byte [] a = {22,        82,        184};


        byte[] en = new byte[]{98,99};
        System.out.println(new String(en));

        // 使用gbk编码
        byte[] cn = "你".getBytes("gbk");
        System.out.println(Arrays.toString(cn));

        // 不加charsetName是使用utf解码
        System.out.println(new String(new byte[]{-60, -29}, "gbk"));
    }
