java - How to read data line by line from String buffer and match with another String -

-

itemprop = "text">

I write code 

  public class keys {personal constant last string} keyss = { "HGDLV-KLLQC-DM3ON-MAUOX-FNQK5", "HQKLD-NYRDL-NJXCV-BVCKF-NRKLC", "LDFCV-BDJCQ-VMFQV-FNRKC-NFCFL" // and many more}; Public static string getKey (string key) {boolean B = Arrays.asList (keyss) .contains (key); If (b == true) {key = "accepted"; } Other {key = "unapproved"; } Return key; }

and all strings are accepted even if the user specified string

Use parallel to the strings Additionally, the implementation of GetKeys () is very complex and redundant. Consider changing it: 

  Public square key {Private Static Last String [key = {"HGDLV-KLWC-DM3-NMUOX -FNQK5 "," HQKLD-NYRDL-NJXCV-BVCKF-NRKLC "," LDFCV-BDJCQ-VMFQV-FNRKC-NFCFL "// and many more}; Public static string getKey {string (current key: {key} {if (current.equals (key)) {return "approved"; }} Return "Disapproved"; }}

is not required, and neither a Boolean switch ..

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
