Java - ArrayList - Get a value from an Array of array -

i save values database using function (i've been replaced vector, because deprecated) :

// database function public arraylist<string[]> selectquery(string query) {     arraylist<string[]> v = null;     string [] record;     int colonne = 0;     try {         statement stmt = db.createstatement();         resultset rs = stmt.executequery(query);         v = new arraylist<string[]>();         resultsetmetadata rsmd = rs.getmetadata();         colonne = rsmd.getcolumncount();          while(rs.next()) {             record=new string[colonne];             (int i=0; i<colonne; i++) record[i] = rs.getstring(i+1);             v.add((string[])record);         }         rs.close();         stmt.close();     } catch (exception e) { e.printstacktrace(); errore = e.getmessage(); }      return v; }  // here print result, after call function arraylist db_result=null; db_result=mydb.selectquery("select titolo, user, date articles category='1' order id asc");  int i=0; while (i<db_result.size() ) {     affitta_3.createlabel().setlabel(db_result.get(i)[0]);     affitta_3.createlabel().setlabel(db_result.get(i)[1]);     affitta_3.createlabel().setlabel(db_result.get(i)[2]);     affitta_3.createlabel().setlabel(db_result.get(i)[3]);    i++; } 

so, save many string-array in array. now, how can (for example) 4° value 2° array string?

why bothering clone string array when nothing else have reference it?

anyway, you'd @ string using:

string value = v.get(1)[3]; 

(assuming v of type list<string[]> or similar).
