问题 This question already has answers here : What are the special dollar sign shell variables? (4 answers) Closed 2 years ago . (I've seen a number of questions here about Bash special parameters. It can be difficult to search for things like $* , both in the Bash manual and via Google. This question is intended to be a general reference for these questions.)

问题 I usually get the current working directory by giving the batch command %~dp0 for combine multiple csv files. But I encountered ampersand (&) symbol while getting current working directories which makes batch file broke after the '&' saying the path after & is not recognized as an internal or external command. Can any of you guys please help me in modifying my below script in identifying & and replacing it with ^& (as this can escape the & and run the batch file). Any of your suggestions is

问题 I want to send the XML request below. Text content should be escaped, but not the tags. I've tried to use below escape logic. String str = escapeXml11(req); However, my whole request is getting escaped. So, it is no longer valid XML. My original string: String req = "<request>\r\n" + " <Products>\r\n" + " <Product>\r\n" + " <ProductName>H < M</ProductName>\r\n" + " <quantity>1</quantity>\r\n" + " <totalProductCost>17.03</totalProductCost>\r\n" + " </Product>\r\n" + " </Products>\r\n" + "<

问题 I want to compare 2 strings which have some non English character in them String1 = debarquer String2 = débárquér On comparing above 2 strings, they should say equal. 回答1: Use the Collator class. It allows you to set a strength and locale and it will compare characters appropriately. It should be something similar to this (NOTE: I have not tested the program) import java.text.Collator; import java.util.Locale; public class CollatorExp { public static void main(String[] args) { Collator

问题 I can't seem to get the regex correct for the following requirement: a string between 8 and 20 length that must contain at least 1 uppercase alphabet character, at least 1 lowercase alphabet character, and either at least 1 digit or at least 1 special character (or both). Let's say special characters are restricted to include just @,#,&,~.
