linked list - Java LinkedLists in LinkedLists - Access items -

i have @ least me tricky thing university do. have create linkedlist in other linkedlists saved.

in these linkedlists text patterns saved, want change them specific commands. however, have no clue how access these linkedlistes. if use .get, receive saved linkedlist object. found no way read items saved within object or earlier linkedlist.

linkedlist listrows = new linkedlist(); linkedlist listcolumn1 = new linkedlist(); linkedlist listcolumn2 = new linkedlist();  listcolumn1.add("test"); listcolumn1.add("test"); listcolumn2.add("hello"); listcolumn2.add("hello");  listrows.add(listcolumn1); listrows.add(listcolumn2);  //here problem now, cannot save linkedlist //because linkedlist giving object linkedlist listedit= new linkedlist(); listedit=listrows.get(0) //<-error  //if use syso, object name printed system.out.println(listrows.get(0)) //printed e.g.: [ljava.lang.string;@55f96302] 

thank in advance help!

you should declare exact types need :

linkedlist<linkedlist<string>> listrows = new linkedlist<>(); linkedlist<string> listcolumn1 = new linkedlist<>(); linkedlist<string> listcolumn2 = new linkedlist<>(); 

then:

linkedlist<string> listedit = listrows.get(0); 

your problem used raw linkedlist type, listrows.get(0) returned instance of object type instead of internal linkedlist.
