You need to convert the inputs to double: System.out.println((double)completed/(double)total); Note that you don’t actually need to convert both of the inputs. So long as one of them is double, the other will be implicitly converted. But I prefer to do … Read more
this is almost what you need 🙂 using tabs List<String> l = new ArrayList<String>(Arrays.asList(ss)){; @Override public String toString(){ Iterator<String> it = iterator(); if (! it.hasNext()) return “”; StringBuilder sb = new StringBuilder(); int i = 0; for (;;) { i++; String e = it.next(); sb.append(e); if (! it.hasNext()) return sb.toString(); sb.append(‘\t’); if (i%4==0){ sb.append(“\n”); } … Read more
