android - Collapse various date computations into one function -

-

i have many functions give number of week of current year, week of year give difference of number of year in year minus current week of year , give modulo of difference two.

i want create single method take 2 input, current year("2013") , current date "26/08/2013" , return difference modulo 2 0 or 1.

int totalweeks = gettotalweeksinyear(2013); int currentweeks = getcurrentweekofyear("26/08/2013");  private int gettotalweeksinyear(int year) {     calendar cal = calendar.getinstance();     cal.set(calendar.year, year);     cal.set(calendar.month, calendar.december);     cal.set(calendar.day_of_month, 31);      int ordinalday = cal.get(calendar.day_of_year);     int weekday = cal.get(calendar.day_of_week) - 1; // sunday = 0     int numberofweeks = (ordinalday - weekday + 10) / 7;     system.out.println(numberofweeks);     return numberofweeks ;  }  private int getcurrentweekofyear(string week) {     // string dtstart = "26/10/2013"; // input date user     string dtstart = week;      simpledateformat format = new simpledateformat("dd/m/yyyy");       try {           date = format.parse(dtstart);     } catch (parseexception e) {           // todo auto-generated catch block           e.printstacktrace();       }     calendar calender = new gregoriancalendar();     calender.settime(date);      return calender.get(calendar.week_of_year) ; }  int diffrence = totalweeks - currentweeks; int remainder = diffrence % 2;  if (remainder == 0) {     toast.maketext(this, "current year weeks 0",      toast.length_short).show();      } else {     if (remainder == 1)     {         toast.maketext(this, "current year weeks 1" ,                         toast.length_short).show();       } } 

int result(int year, string week) {  simpledateformat format = new simpledateformat("dd/m/yyyy");   calendar cal1 = calendar.getinstance(); cal1.set(calendar.year, year); cal1.set(calendar.month, calendar.december); cal1.set(calendar.day_of_month, 31);  try {       date date = format.parse(week); } catch (parseexception e) {        e.printstacktrace();   }  calendar cal2 = new gregoriancalendar(); calender.settime(date);  return ((( cal.get(calendar.day_of_year) - (cal.get(calendar.day_of_week) - 1) + 10) / 7) - cal2.get(calendar.week_of_year) %2) ;  }

though wonder, there isn't logic involved why couldn't write it.

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...

this question has answer here: meaning of .this , .class in java 2 answers i'll straight point. im still learning bit of syntax , want know difference between code is code a: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.valueof(i))); } } please ignore fact i undeclared, not lost. code b: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.this.charat(i))); } } what don't yet understand difference in typing string.this , string. i under assumption when use dot operator on class accessing it's static methods(and/or variables if they're not hidden). i have studied little bit , have concluded when using string. accessing string static methods.. when using string.this. i'm accessing methods class buttonz extendi...
