Java 正則表達式

語法：https://msdn.microsoft.com/zh-cn/library/ae5bf541(v=vs.80).aspx 

一、車牌號：

/**

* 

* @description:驗證車牌號

* @param carNum

*            豫A106EK

* @return 合法：true 不合法：false

*/

public static boolean validateCarNum(String carNum) {

boolean result = false;

String[] provence = new String[] { "京", "津", "冀", "晉", "遼", "吉", "黑", "滬", "蘇", "浙", "皖", "閩", "贛", "魯", "豫", "鄂", "湘", "粵", "桂", "瓊", "渝",

"川", "黔", "滇", "藏", "陝", "甘", "青", "寧", "新", "港", "澳", "蒙" };

String reg = "[\u4e00-\u9fa5]{1}[A-Z]{1}[A-Z_0-9]{5}";

boolean firstChar = false;

if (carNum.length() > 0) {

firstChar = Arrays.asList(provence).contains(carNum.substring(0, 1));

}

try {

Pattern p = Pattern.compile(reg);

Matcher m = p.matcher(carNum);

if (m.matches() && firstChar) {

result = true;

} else {

result = false;

}

} catch (Exception e) {

e.printStackTrace();

}

return result;

}

二、手機號碼：

/**

* 

* @description:驗證手機號碼

* @param mobileNum 15516985859

* @return 合法：true 不合法：false

*/

public static boolean isMobileNum(String mobileNum) {

boolean result = false;

try {

Pattern p = Pattern.compile("^((13[0-9])|(15[^4,\\D])|(18[0,5-9]))\\d{8}$");

Matcher m = p.matcher(mobileNum);

result = m.matches();

} catch (Exception e) {

e.printStackTrace();

}

return result;

}

手機號+固定電話：010-1111111,15516985859,0377-1111111

//java檢測是否爲電話號碼（手機、固定電話驗證）

String legalPhone = "";
String regExp ="^((13[0-9])|(15[^4,\\D])|(18[0,5-9]))\\d{8}|[0]{1}[0-9]{2,3}-[0-9]{7,8}$";
Pattern p = Pattern.compile(regExp);
Matcher m = p.matcher(importPotentialBFOs[i].getLegalPhone());
if(m.find()){ //注意：m.find只能用一次，第二次調用後都爲false
 legalPhone = importPotentialBFOs[i].getLegalPhone();
 uploadTmp.setLegalTelephone(legalPhone);

}else{
 throw new BizException("聯繫電話格式錯誤!");
}

3.實數：

 String[] arrs=new String[]{"a","1.123","-1.23","0","+111"};

            String regex="-?\\d+\\.?\\d*";

            Pattern p = Pattern.compile(regex);

            for (int i = 0; i < arrs.length; i++) {

            Matcher m = p.matcher(arrs[i]);

            System.out.println(arrs[i]+":"+m.matches());

}

打印：

a:false

1.123:true

-1.23:true

0:true

+111:false

四、替換全部的標點符合

String reg="[\\p{P}]";
