java - Printing a diamond - can't enter input? -


i'm trying write program outputs diamond pattern this:

   *   ***  *****   ***    *

i've started trying first print top half of diamond.

i can input 'totallines' console, can't type when prompts 'character'. why happening?

we've been using joptionpane of our assignments, makes sense i'd having trouble this, can tell reading book, correct.

(and if have time talk me for-loops, i'm pretty sure need work. i'd grateful.)

public static void main(string[] args) {      scanner input = new scanner(system.in);      int totallines, lines, currline = 1, spaces, maxspaces, minspaces, numcharacters, maxcharacters, mincharacters;      string character;      system.out.print("enter total number of lines: ");     totallines = input.nextint();     system.out.print("enter character used: ");     character = input.nextline();      lines = ((totallines + 1)/2);     // spaces = (math.abs((totallines + 1)/2)) - currline;     maxspaces = (totallines + 1)/2 - 1;     minspaces = 0;     // numcharacters = (totallines - math.abs((totallines +1) - (2*currline)));     maxcharacters = totallines;     mincharacters = 1;     spaces = maxspaces;      (currline = 1; currline<=lines; currline++) {         (spaces = maxspaces; spaces<=minspaces; spaces--){             system.out.print(" ");             }         (numcharacters = mincharacters; numcharacters>= maxcharacters; numcharacters++){             system.out.print(character);             system.out.print("\n");         }         }       }

try using next() instead of nextline().

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
