java - Reading a file of txt to be fed into an array -

-

Here a user enters the list of 1 and 0 .... then an input will be 10001010. But I have to read this from a text file ... In my text file input.txt there are also 10001010 ... the coverDataArray array is required to feed the same string from a file to the console.

I tried the data stream though, it throws an exception to me

'

...

..... 

  try {System.out.println ("Enter binary bits" ); Data1 = in.next (); For (int i = 0; i & lt; data1.length (); i ++) {covertDataArray [i] = byte Parsbyte (data 1.substring (i, i + 1)); } '   
 
 
 You can pass an  file  object instead For the  System.in  scanner constructor it is shown below:  
  string filename = "input.txt"; File file = new file (filename); Scanner scanner = new scanner (file); String s = ""; While (scanner.hasNextLine ()) {s = scanner.nextLine (); // your code. You can use scanner.next () to read words by word instead of nextLine ()}    .

Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

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
