java - Checking for data in array indexes -

-

I am trying to create a program that will be read in a file, split that file into an array where " "And then the variable" theOutput "is set as the value of the index in the array. The problem is that the index is always equal to the null. Here is my code: 

  string theOutput = null; String content = new scanner (new file ("URL.txt"). UseDelimiter ("\\ Z"). Next (); TheInput = content; string [] URL = theInput.split ("/"); Println (theInput ); Println (URL.length); if (URL.length == 1) {theOutput = URL [0]; if (URL.length == 3) {theOutput = URL [2]; if (URL.length == 4) {theOutput = URL [3]; if (URL.length == 5) {theOutput = URL [4]; if (URL.length == 6) {theOutput = URL [5];}}}   
 An example of the data found in the file will be "coffee: // localhost / bru", so it does not always use index 5 in the array.   
 
 
 If your statement is a different If the nest is nested in, then  if (URL.length == 3)  only the length of the URL will be 1 if 1. So, you should do something like this:  
  If (URL.length == 1) {theOutput = URL [0];} if (URL.length == 2) {theOutput = URL [1]} // etc.   
 Or, you can ask  theOutput = URL [URL.length-1]  to get the last element of the array.

After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
