will send servlet

}

the question run or not if not why? please dont criticize way code our college prof slow , dosent know doing , besides pretty sleepy when coded yeah flawed logic

the code provide run fine. i'm running code with:

  • eclipse luna
  • tomcat 7
  • dynamic web application server (version 2.5)

as mentioned fix error can change tomcat port configuration. see details available on how change tomcat default port

java - UML - How would you draw a try catch in a sequence diagram? -

Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
