如何知道我的字符串是否以{n}个前导零开头？ 例如下面，条件将返回true，但我的真实目的是检查字符串实际上是否仅以2个零开始。

String str = "00063350449370"

if (str.startsWith("00")) { // true
    ...
}

这将确保字符串以“00”开头，但不是更长的零字符串。

答案 1 :(得分：1)

怎么样？

final String zeroes = "00";
final String zeroesLength = zeroes.length();
str.startsWith(zeroes) && (str.length() == zeroes.length() || str.charAt(zeroes.length()) != '0')

答案 2 :(得分：1)

你可以试试这个正则表达式

boolean res = s.matches("00[^0]*");

答案 3 :(得分：1)

慢但是：

if (str.matches("(?s)0{3}([^0].*)?") {

这使用(?s) DOTALL选项让.也匹配换行符。

0{3}适用于3场比赛。

答案 4 :(得分：1)

使用正则表达式怎么样？

0{n}[^0]*

其中n是您想要的前导'0'的数量。您可以使用Java regex API来检查输入是否与表达式匹配：

Pattern pattern = Pattern.compile("0{2}[^0]*"); // n = 2 here
Matcher matcher = pattern.matcher(input);
if (matcher.matches()) {
    // code
}

答案 5 :(得分：0)

您可以使用正则表达式来评估String值：

String str = "00063350449370";
String pattern = "[0]{2}[1-9]{1}[0-9]*"; // [0]{2}[1-9]{1} starts with 2 zeros, followed by a non-zero value, and maybe some other numbers: [0-9]*
if (Pattern.matches(pattern, str))
{
    // DO SOMETHING
}

可能有一个更好的正则表达式来解决这个问题，但如果您选择正则表达式路径，这应该会让您大致了解如何继续。

答案 6 :(得分：0)

漫长的道路

WITH mySums AS
(
    SELECT ROW_NUMBER() OVER(ORDER BY T1.CardCode /*find your fitting order*/) AS PseudoIndex,
     T3.[SlpName], T1.[CardCode], T1.[CardName], T1.[ShipToCode], T2.[ItemCode], T2.[Dscription], 
    SUM(T2.[Quantity]) AS 'Total Quantity',
    MAX(T2.[Price]) AS 'Line Price', 
    SUM(T2.[LineTotal]) AS 'Line Total', 
    SUM(T2.[GrssProfit]) AS 'Gross Profit' 
    FROM OCRD T0 INNER JOIN OINV T1 ON T0.[CardCode] = T1.[CardCode] INNER JOIN INV1 T2 ON T1.[DocEntry] = T2.[DocEntry] INNER JOIN OSLP T3 ON T0.[SlpCode] = T3.[SlpCode]
    WHERE T3.[SlpName] = 'Name' AND T1.[createdate] >= DATEADD(day,-7, GETDATE())
    GROUP BY T3.[SlpName], T1.[CardCode], T1.[CardName], T1.[ShipToCode], T2.[ItemCode], T2.[Dscription]
)
SELECT tbl.* FROM
(
    SELECT * FROM mySums
    UNION 
    SELECT 100000,NULL,NULL,NULL,NULL,NULL,NULL,SUM([Total Quantity]),SUM([Line Price]),SUM([Line Total]),SUM([Gross Profit])
    FROM mySums
) AS tbl
ORDER BY tbl.PseudoIndex

虽然

可能会更好地使用小循环 
    String TestString = "0000123";
    Pattern p = Pattern.compile("\\A0+(?=\\d)");
    Matcher matcher = p.matcher(TestString);

    while (matcher.find()) {
          System.out.print("Start index: " + matcher.start());
          System.out.print(" End index: " + matcher.end() + " ");
          System.out.println(" Group: " + matcher.group());
    }
