java - Trying to debug int arrays -

i'm trying put little game concept in java, , have encountered strange problem; int arrays don't seem storing values in parts of code!
(using netbeans 8.2)
suspect small , tedious have missed.
constructor basic creature. see "addtrait" method? focus.

public creature(string inputname) {     if(debug>0){system.out.println("debug: creature ");}      creaturename = inputname;     size = 1;     population = 1;      addtrait(new trait("test",0,new int[]{4,4,4,4,4,4}),0);     addtrait(new trait("empty",0,new int[]{0,0,0,0,0,0}),1);     addtrait(new trait("empty",0,new int[]{0,0,0,0,0,0}),2);  } 

this method in creature class.

public void addtrait(trait newtrait, int slotnum) {     mytraits[slotnum] = newtrait;      if(debug>0){system.out.println("debug: creature > "             + "addtrait > mytraits["+slotnum+"].getname() = "+             mytraits[slotnum].getname());}           for(int k=0;6>k;k++)         {             system.out.println("debug: creature > "             + "addtrait > mytraits["+slotnum+"].geteffects()["+k+"] = "+             mytraits[slotnum].geteffects()[k]);         }          system.out.println(); } 

in driver class, attempt add "sharp eyesight" trait test creature.

public class evodriver { public static void main(string[] args) {      // initilize traitlist       traitlist mytraits = new traitlist();      // initilize creature      creature player1 = new creature("dragon bear");      player1.addpop();     player1.addpop();     player1.growsize();      // add specific trait      //player1.addtrait(mytraits.gettrait("carnivore"), 0);     player1.addtrait(mytraits.gettrait("sharp eyesight"), 1);     //player1.addtrait(mytraits.gettrait("fire breath"), 2);      //force update     player1.updatestats();     //print creature     player1.printcreature();    } 

this constructor trait.

public trait(string newname, int fv, int[] effects) {     if(debug>0){system.out.println("debug: trait");}      traitname = newname;     feedvalue = fv;      //handle effects     effects[0] = feedertype;     effects[1] = size;     effects[2] = power;     effects[3] = stealth;     effects[4] = senses;     effects[5] = dangerous;      if(debug>0){system.out.println("debug: trait > traitname = "+traitname);}     if(debug>0){system.out.println("debug: trait > senses = "+senses);}  } 

i have class supposed handle initiating stat boosts each trait called traitlist. holds data each trait. however, when method "geteffects" called, result 0!

public class traitlist {  //debug mode  final int debug = 1;    trait[] alltraits = {new trait("empty",0,new int[]{0,0,0,0,0,0})};  // **** constructors ****  /*                              hints ____________________________________________________________________________ effects[0] = feedertype; effects[1] = size; effects[2] = power; effects[3] = stealth; effects[4] = senses; effects[5] = dangerous; */   public traitlist() {      if(debug>0){system.out.println("debug: traitlist ");}        boolean[] special = new boolean[2];     special[0] = false; //alert herd     special[1] = false; //pack tactics      //add effects list      // sharp eyesight; increases senses 3      //feedertype;     //size;     //power;     //stealth;     //senses;     //dangerous;     addtrait(new trait("sharp eyesight", 2, new int[]{0,0,0,0,3,0} )             .setdesc("helps detect other creatures!"));      // camouflage; increases stealth 3      addtrait(new trait("camouflage", 0, new int[]{0,0,0,0,0,0}));      // alert herd; increases senses population number     addtrait(new trait("alert herd", 0, special));      // pack tactics; increases power population number     addtrait(new trait("pack tactics", 0, special));      // carnivore; creature can eat meat; senses +1, stealth +1      addtrait(new trait("carnivore", -1, new int[]{0,0,0,0,0,0}));      // omnivore; creature can eat meat , plants      addtrait(new trait("omnivore", -5, new int[]{0,0,0,0,0,0}));      // horns; increases dangerous 1      addtrait(new trait("horns", 0, new int[]{0,0,0,0,0,0}));       // fire breath; increases dangerous 3, increases power 3; feed 10      addtrait(new trait("fire breath", 10, new int[]{0,0,0,0,0,0})); }  // **** methods ****  public void addtrait(trait newtrait) {     // create temp array     trait[] temp = new trait[1];      temp[0] = newtrait;     trait[] newtemp = new trait[alltraits.length+1];     (int k=0; alltraits.length>k;k++)     {         newtemp[k] = alltraits[k];     }        newtemp[alltraits.length] = temp[0];      alltraits = newtemp;     }  public trait getrandomtrait() // {     return null; }  public int gettraitindex(string searchname)//returns 0 if not found {      for(int k=0;alltraits.length>k;k++)     {         if(debug>0)         {system.out.println("debug: traitlist > gettraitindex > k = "+k);}          if(debug>0)         {system.out.println("debug: traitlist > gettraitindex > "                 + "alltraits[k].getname() = "+alltraits[k].getname());}          if(searchname.equalsignorecase(alltraits[k].getname()))         {             return k;         }     }     system.out.println("error in traitlist > gettraitindex! trait "              + searchname +" not exist!");     return 0; }  public trait gettrait(string name)//returns empty trait if not found {     return alltraits[gettraitindex(name)]; } 

}

i don't know how clear i've been, appreciate hints, advice, hell i'd take useful insult pointing out stupid mistakes. attach debug output.

if no solution can found, i'll start on scratch. (i'll reuse bits of working code of course!)

in constructor, re-assigning values of effects. potential problem.

effects[0] = feedertype; effects[1] = size; effects[2] = power; effects[3] = stealth; effects[4] = senses; effects[5] = dangerous;
