"loop_maxJetPT()" : hata duzeltme :
//len=kMaxJet;
   len=e6.Jet_size;
#include "exercise1.h" : bunu nereden çıkarıp ekliyor NetBeans bilmiyorum, faydası yok, zararı var.
"initializeTTree(TTree* t, Double_t* adresler, int len_Fields, const char* branchNamePrefix, const char* fields[])" : in "initializeTTree4Something()" methods, a big piece of code was redundant. I implemented that piece of code in another method to eliminate redundancy of code. From now on, "initializeTTree4Something()" will call this method instead of executing redundant code.
Artık "initializeTTree4Something()" metodu "initializeTTree()" yi kullanıyor.
"initializeTTree4Jet()" ve "fillTTree4Jet()" : tamamlandı, henüz denemedim.
