java - Why do I get "cannot find symbol" using scanner when compiling? -


i'm learning java here, wrote simple program, error every time try compile it. error get:

trivia.java:14: error: cannot find symbol ret = sc.nextline();         ^

the program follows:

import java.util.scanner;  class gamestart {   public static void main(string[] args){    scanner sc = new scanner(system.in);    string ret;    byte qnum;    string ans;   string correct = "awesomely correct!";  string wrong = "darn it! got it!";   system.out.println("do think know stuff?");  ret = sc.nextline;   if (ret.equals("yes") || ret.equals("yes"))  {  system.out.println("well, let's test know! choose number 1 5!"); qnum = sc.nextbyte();   switch (qnum)   {     case 1:     system.out.println("in year did french revolution start?");     ans = sc.nextline();       if (ans.equals("1789") || ans.equals("seventeen eighty nine"))       {       system.out.println(correct);       }       else       {       system.out.println(wrong);       }      break;      case 2:     system.out.println("how many protons sodium atom have?");     ans = sc.nextline();       if (ans.equals("11") || ans.equals("eleven"))       {       system.out.println(correct);       }       else       {       system.out.println(wrong);       }      break;      case 3:     system.out.println("what 2^6*0.5-12?");     ans = sc.nextline();       if (ans.equals("20") || ans.equals("twenty"))       {       system.out.println(correct);       }       else       {       system.out.println(wrong);       }      break;      case 4:     system.out.println("which lowest numbered element in periodic table?");     ans = sc.nextline();       if (ans.equals("hydrogen") || ans.equals("hydrogen"))       {       system.out.println(correct);       }       else       {       system.out.println(wrong);       }      break;      case 5:     system.out.println("which unit measures coulombs per second?");     ans = sc.nextline();       if (ans.equals("ampere") || ans.equals("ampere"))       {       system.out.println(correct);       }       else       {       system.out.println(wrong);       }      break;     default:     system.out.println("stick rules! 1-5!");   }   }  else  {  system.out.println("not liking attitude, want hear big yes!");  }  } }

as mentioned, i'm pretty new in java, you'll find more errors sure, , "style" may terrible, suggestions welcome! :)

you have forgotten add () brackets in line

ret = sc.nextline;

also nextline not nextline

change ret = sc.nextline; 

 ret = sc.nextline();

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
