java - variable may have not been initialized? -

so in while loop print elements of arraylist store. afterwards when call it, says array may have not been initialized.

any thoughts? i'm trying read file of lines. each line has @ least 8 elements, , i'm sure array not empty because printed in while loop.

?

public class readerfile {     public static scanner input;     public static scanner input2;      /**      * @param args command line arguments      */     public static void main(string[] args) {          int count=0;         arraylist<team> store;         arraylist<robot> store2;         //robot robot;          string filelocation = "tourney2teams.csv";         string filelocation2 = "tourney1robots.csv";           try{             input = new scanner(new file(filelocation)).usedelimiter(",");         }         catch (ioexception ioexception)         {             system.out.print("problem");         }           try {             input2 = new scanner(new file (filelocation2)).usedelimiter(",");         }         catch (ioexception ioexception)         {             system.out.print("problem robot");         }           try{                 input.nextline();                 system.out.print("please\n");                 int countt = 0;                 while(input.hasnext())                 {                         //int countt = 0;                         int id = input.nextint();                         string teamname = input.next();                         string coachfirst = input.next();                         string coachlast = input.next();                         string mentorfirst = input.next();                         string mentorlast = input.next();                         string teamfs = input.next();                         string teamss = input.next();                         input.nextline();                         store = new arraylist<>();                         team team = new team (teamname, id, coachfirst, coachlast,mentorfirst,mentorlast,teamfs,teamss);                         store.add(team);                         system.out.print("team numer"+store.get(0).teamnumber+"\n");                         countt = countt+1;                         system.out.print("\n"+countt);                 }         }         catch (nosuchelementexception statexcemtion)         {             system.out.print("\nankosh");         }         string x = store.get(2).teamname;     } } 

store = new arraylist<>(); 

this line reinitializes store @ every pass in while. want initialize before while accumulate while looping.

it says not initialized because reason never executed while loop (empty input).
