Java: Comparing two lists -

-

मेरे पास दो सूचियां हैं उदाहरण के लिए: 

  ए = {21, 41, 96, 02} बी = {21, 96, 32, 952, 1835}

क्या मैं इच्छित परिणामस्वरूप यह है: आर = {32, 952, 1835}

इसे पसंद करें:

इसके बाद मैं परिणाम R से ए : 

  ए = {21, 41, 96, 02, 32, 952, 1835}

यह आसान है:) 

  सूची & lt; पूर्णांक & gt; ए = नया अर्रेलिस्ट & lt; & gt; (Arrays.asList (21, 41, 96, 02)); सूची के & lt; पूर्णांक & gt; बी = नया अर्रे लिस्ट & lt; & gt; (Arrays.asList (21, 96, 32, 952, 1835)); B.removeAll (a) // अब सूची बी में शामिल हैं (32, 952, 1835) a.addAll (b); // अब इसमें शामिल सूची (21, 41, 96, 02, 32, 9 52, 1835)

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
