List of List in for loops Java -

i have problem. try develop program ask me numbers few times. give list of numbers. try save them in list>. numbers can split space. have code :

import java.util.arraylist; import java.util.list; import java.util.scanner; public class timeseries {  public static void main(string[] args) {     // todo auto-generated method stub      system.out.println("numbers of rows:");     scanner in = new scanner(system.in);     int numberlines = in.nextint();     in.nextline();     string ciag;     list<list<integer>> ll = new arraylist<list<integer>>();     list<integer> list = new arraylist<integer>();     (int = 0; < numberlines; i++) {         list.clear();         system.out.println("add row " +(i+1));         ciag = in.nextline();         (int t=0; t<ciag.length(); t++) {              if(character.iswhitespace(ciag.charat(t)))             {              }             else             {list.add(character.getnumericvalue(ciag.charat(t)));             }          }          system.out.println(list);         ll.add(list);         }      system.out.println(ll);  }       } 

but output (example) :

numbers of rows: 3 add row 1 0 0 0 [0, 0, 0] add row  2 1 2 3 [1, 2, 3] add row  3 54 6 8 [5, 4, 6, 8] [[5, 4, 6, 8], [5, 4, 6, 8], [5, 4, 6, 8]] 

but need have [[0,0, 0], [1, 2, 3], [5, 4, 6, 8]]

the problem add the same list ll multiple times. need add different lists behavior want. that, need create fresh new list in each iteration of for loop, instead of clearing , reusing existing list.

change these lines:

list<list<integer>> ll = new arraylist<list<integer>>(); list<integer> list = new arraylist<integer>(); (int = 0; < numberlines; i++) {     list.clear(); 

to this:

list<list<integer>> ll = new arraylist<>(); (int = 0; < numberlines; i++) {     list<integer> list = new arraylist<>();
