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();  
}
