arrays splitting strings java -

-

I'm sure this is a fairly easy question for anyone, but I think it's the best way to do it as a relative. Tell me the beginners.

I am dividing a large file (string temporary) into approximately 100 strings and setting it as an array, but I do not know the exact number of strings. 

  string [] idf = temp.split ("==========="); String class 1 = IDF [0]; String class 2 = IDF [1]; String Class 3 = IDF [1]; e.t.c.

What's the best way to ensure that I can split all the stars and store them in an array?

Any suggestions or hints will be most thanked

You can do this Are: 

  string list = "hey, how are you"; String [] strarray = list.split ("\\ s +"); (String str: stray) {System.out.print (str); }

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
