如何删除字符串开头的所有"0"？
00011 -> 11
00123 -> 123
000101 -> 101
101 -> 101
000002500 -> 2500
我试过了：
Pattern pattern = Pattern.compile("([1-9]{1}[0-9]?+)");
Matcher matcher = pattern.matcher("00049");
matcher.matches();
whatYouNeed = matcher.group();
我有错误：No match found
答案 0 :(得分：3)
我试试
System.out.println("Status: " + "00012010003".replaceAll("^0+", ""));
或仅限正则表达式：
yourString.replaceAll("^0+", "");
其中
^ - matches only at start of string
0 - matches literal zeroes
+ - matches consecutive zeroes (at least one)
答案 1 :(得分：2)
您应该将replaceAll与^0*一起使用，并替换为empty string，而不是找到匹配。
答案 2 :(得分：2)
如果您的String仅包含问题中所述的数字。您可以使用String.valueOf(Integer.parseInt("00011"))
答案 3 :(得分：0)
您必须使用正则表达式replaceFirst()和String val = "000011100";
String newVal = val.replaceFirst("(?<=^)0+", "");
System.out.println(newVal);
进行此操作
但是如果它是另一种形式，则在regex之前将你的值解析为string。
11100
输出
?<=^其中
0背后隐藏着。正则表达式模式仅匹配^与 <script>

if (objMerchant.CurrentCityID != 0 && objMerchant.CurrentCityID != objMerchant.CityID)
objMerchant.CityID = objMerchant.CurrentCityID;
if (objMerchant.CurrentStateID != 0 && objMerchant.CurrentStateID != objMerchant.StateID)
objMerchant.StateID = objMerchant.CurrentStateID;

匹配，即后面的字符串开头。
