Java Basics __ Randomly generate numbers between 1~15

 Packagetext;Importjava.util.ArrayList;Importjava.util.List; Public classText { Public Static voidMain (string[] args) {//create a linked list of an integer collectionlist<integer> L =NewArraylist<integer>(); //End-of- chain table Insert data when a list of 15 numbers is present         while(L.size () <15){          inti = (int) (Math.random () *15+1); if(!l.contains (i)) l.add (i); }        //iterating, outputting elements in a linked list//for (int j:l)//System.out.println (j);         for(intI=0;i<l.size (); i++) {System.out.println (L.get (i)); }            }}
