  • Retrieving the value of a concatenated variable within a Java FOR loop

    - by Rajat
    I have been using this "logic" in C++ and VB with success, but am tied up in Java... Simply put, public void DataProviderExample(String user, String pwd, String no_of_links, String link1, String link2, String link3) { for (int i=1;i<=no_of_links;i++) { String link = "link"+i; System.out.println(link); } Now, if the variables link1, link2 and link3 have a value of "X", "Y" and "Z" respectively, upon running this program, I get the following output - link1 link2 link3 What I want is - X Y Z Any ideas?

  • At What point should you understand pointers?

    - by Vaccano
    I asked a question like this in an interview for a entry level programmer: var instance1 = new myObject{Value = "hello"} var instance2 = instance1; instance1.Value = "bye"; Console.WriteLine(instance1.Value); Console.WriteLine(instance2.Value); The applicant responded with "hello", "bye" as the output. Some of my co-workers said that pointers are not that important anymore or that this question is not a real judge of ability. Are they right?

  • Why is ColdFusion adding whitespace when I call a function in cfoutput?

    - by Kip
    If I do something like this in ColdFusion: <cfoutput>foo="#foo()#"</cfoutput> The resulting HTML has a space in front of it: foo=" BAR" However, if it is not a function call it works fine, i.e.: <cfset fooOut=foo() /> <cfoutput>foo="#fooOut#"</cfoutput> Gives this output: foo="BAR" Where is this extra space coming from and is there anything I can do about it?

  • simple interview question

    - by calvin
    Input integer array: a[8] = { a1, a2, a3, a4, b1, b2, b3, b4 } Output array: a[8] = { a1, b1, a2, b2, a3, b3, a4, b4 } Forget all corner cases, make sure your solution works for any int array of size 2n. You can use one or two temp variables for looping or anything, but you shouldn't use any temp arrays/stacks/queues etc to store entire array or part of array. I'm able to get answer in O(n*log n), but I'm looking for better solution.

  • regex help using repreated groups

    - by Chris H
    I'm trying to match rc-update -s output in python. m = re.match(r"^\s*(\w+)\s*\|{\s*(\w+)\s*}*$", " network | level1 level2 leveln ") but m is always None the hard part for me is getting the regex to match the n levels. I thought that using {}* would match the n levels, but as soon as I add the {} nothing matches. thanks.

  • Can i get RSpec to generate specs with expect syntax?

    - by papirtiger
    When generating specs with : rails g controller Home index A spec is generated with the older object.should syntax require 'spec_helper' describe HomeController do describe "GET 'index'" do it "returns http success" do get 'index' response.should be_success end end end Is it possible to configure the generator to use the expect syntax instead? Desired output: require 'spec_helper' describe HomeController do describe "GET 'index'" do it "returns http success" do get 'index' expect(response).to be_success end end end in config/application.rb: config.generators do |g| g.test_framework :rspec, fixture: true g.fixture_replacement :factory_girl, dir: 'spec/factories' g.view_specs false g.stylesheets = false g.javascripts = false end

  • Setting end-of-line character for puts

    - by Dom De Felice
    I have an array of entries I would like to print. Being arr the array, I used just to write: puts arr Then I needed to use the DOS format end-of-line: \r\n, so I wrote: arr.each { |e| print "#{e}\r\n" } This works correctly, but I would like to know if there is a way to specify what end-of-line format to use so that I could write something like: $eol = "\r\n" puts arr UPDATE I know that puts will use the correct line-endings depending on the platform it is run on, but I need this because I will write the output to a file.

  • Replace all URL unless it is allowed

    - by ratamaster
    I had a regex that replaced all URLs from a given string: my_string = "www.example.com test www.mysite.com" my_string.gsub!(/[a-zA-Z0-9\-\.]+\.(com|net|de|org|uk|biz|info|co.uk|es|de)(\/\S*)?/i,'(site hidden)') As a result of the above I get: "(site hidden) test (site hidden)" How could I change the regex to not replace www.mysite.com ??? It means that the replace should output "(site hidden) test www.mysite.com" Thanks !
