问题 I am writing a library for our company's product that will take any kind of architectural dimension that our users are already familiar with as input for a function that converts from a string to a double. Here is the list of input types that we would like to be valid. Input | Meaning | Output (Inches represented by a double) 12.5' | 12 Feet and six inches | 150.0 11" | 11 Inches | 11.0 3/16" | 3 sixteenths of an Inch | 0.1875 spaces may or may not be used between the feet and inches and the

DateTime.ParseExact - how to parse single- and double-digit hours with same format string?

由 自作多情 提交于 2019-12-08 16:35:37
问题 I want to be able to parse strings of time (hours, minutes, seconds) where the hours run from 0 to 23, and where the preceding zero for one-digit hours is optional. Examples of time strings that I want to be able to parse into valid DateTime objects: 212540 061525 94505 I am trying to use the C# method DateTime.ParseExact to manage the parsing, but I cannot for the life of it come up with a format string that can handle the "single-digit hour without preceding zero" scenario. How should I

Why does Integer.parseInt(“\uD835\uDFE8”) fail?

由 我怕爱的太早我们不能终老 提交于 2019-12-08 08:57:50
问题 I was under the impression that java supports unicode characters. I made this test and sadly found that it fails. The question is why? Is it a bug or somewhere documented? // MATHEMATICAL SANS-SERIF "𝟨" String unicodeNum6 = "\uD835\uDFE8"; int codePoint6 = unicodeNum6.codePointAt(0); int val6 = Character.getNumericValue(codePoint6); System.out.println("unicodeNum6 = "+ unicodeNum6 + ", codePoint6 = "+ codePoint6+ ", val6 = "+val6); int unicodeNum6Int = Integer.parseInt(unicodeNum6); This

sscanf equivalent in Java [duplicate]

由 ♀尐吖头ヾ 提交于 2019-12-07 07:47:43
问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: what is the Java equivalent of sscanf for parsing values from a string using a known pattern? I'm pretty new to Java, but seeing how useful the sscanf function is, I wonder if there is an equivalent in Java. I've got many pretty much formatted strings (namely, writing scripting language for my purposes), so regular expressions are overkill here. 回答1: Scanner scanner = new Scanner ("2 A text 3 4"); scanner

How to remove unbalanced/unpartnered double quotes (in Java)

由 陌路散爱 提交于 2019-12-07 07:31:12
问题 I thought to share this relatively smart problem with everyone here. I am trying to remove unbalanced/unpaired double-quotes from a string. My work is in progress, I might be close to a solution. But, I didn't get a working solution yet. I am not able to delete the unpaired/unpartnered double-quotes from the string. Example Input string1=injunct! alter ego." string2=successor "alter ego" single employer" "proceeding "citation assets" Output Should be string1=injunct! alter ego. string2

Regex with non-capturing group in C#

由 走远了吗. 提交于 2019-12-06 18:26:37
问题 I am using the following Regex JOINTS.*\s*(?:(\d*\s*\S*\s*\S*\s*\S*)\r\n\s*)* on the following type of data: JOINTS DISPL.-X DISPL.-Y ROTATION 1 0.000000E+00 0.975415E+01 0.616921E+01 2 0.000000E+00 0.000000E+00 0.000000E+00 The idea is to extract two groups, each containing a line (starting with the Joint Number, 1, 2, etc.) The C# code is as follows: string jointPattern = @"JOINTS.*\s*(?:(\d*\s*\S*\s*\S*\s*\S*)\r\n\s*)*"; MatchCollection mc = Regex.Matches(outFileSection, jointPattern );
