public void method() {     try {         list<list<string>> list = testdao.methodname();         list<classname> classname= new arraylist<classname>();         (iterator<list<string>> iterator = list.iterator(); iterator.hasnext();) {             list<string> list2 = (list<string>) iterator.next();             int = 0;             classname classname= new classname ();             (iterator<string> iterator2 = list2.iterator(); iterator2.hasnext();) {                 string string = (string) iterator2.next();                 /* system.out.println(string); */                 if (i == 0)                     classname.setcol1(string);                 else if (i == 1)                     classname.setcol2(long.parselong(string));                 else if (i == 2)                     classname.setcol3(string);                 i++;              }             odhs.add(classname);              system.out.println(classname);             // system.out.println(classname.col2());             // system.out.println(classname.col3());         }         // system.out.println("total size: "+ odhs.size());     } catch (exception e) {         e.printstacktrace();     } }

but got output 

com.project.model.classname@61af1510 com.project.model.classname@37af1f93 com.project.model.classname@778d82e9 com.project.model.classname@408e96d9 com.project.model.classname@59901c4d com.project.model.classname@168cd36b com.project.model.classname@d8d9199 com.project.model.classname@3901f6af
