字符串转与ASCII码之间的互换

1.字符串转换成ASCII码

    public static String stringToAscii(String value)
    {
        StringBuffer sbu = new StringBuffer();
        char[] chars = value.toCharArray();
        for (int i = 0; i < chars.length; i++) {
            if(i != chars.length - 1)
            {
                sbu.append((int)chars[i]).append(",");
            }
            else {
                sbu.append((int)chars[i]);
            }
        }
        return sbu.toString();
    }

2.ASCII码转换成字符串

public static String asciiToString(String value)
{
    StringBuffer sbu = new StringBuffer();
    String[] chars = value.split(",");
    for (int i = 0; i < chars.length; i++) {
        sbu.append((char) Integer.parseInt(chars[i]));
    }
    return sbu.toString();
}
