Java和Android对Mac地址加1或者减1

/** * Mac + 1 * @author YOLANDA * @return */public static String getMacAdd1(String mac){String lastChar = mac.substring(mac.length() – 1).toUpperCase(Locale.getDefault());mac = mac.substring(0, mac.length() – 1).toUpperCase(Locale.getDefault());if("F".equals(lastChar)){lastChar = "0";} else {int tempChar = Integer.parseInt(lastChar, 16) + 1;lastChar = Integer.toHexString(tempChar).toUpperCase(Locale.getDefault());}return (mac + lastChar);}/** * Mac减1 * @author YOLANDA * @param mac * @return */public static String getMacMinus1(String mac){String lastChar = mac.substring(mac.length() – 1).toUpperCase(Locale.getDefault());mac = mac.substring(0, mac.length() – 1).toUpperCase(Locale.getDefault());if("0".equals(lastChar)){lastChar = "F";} else {int tempChar = Integer.parseInt(lastChar, 16) – 1;lastChar = Integer.toHexString(tempChar).toUpperCase(Locale.getDefault());}return (mac + lastChar);}

上一篇Java、Android去掉Mac地址冒号:，给Mac地址加上冒号:下一篇Android和Java判断字符串是否是中文
