thanks in advance!

import java.util.scanner; import java.io.*; class filereadingexercise {   public static void main (string [] args)   {     scanner userinput = new scanner(system.in);     scanner fileinput = null;     {         try         {             system.out.println("please enter name of file or type quit finish");             string = userinput.nextline();             if(a.equals("quit"))             {                 system.exit(0);             }             fileinput = new scanner(new file(a));                           //inline expression          }         catch (filenotfoundexception e)         {             system.out.println("error - file not exist");              //read document there more         }     }     while (fileinput == null);     while(fileinput.hasnext())     {         string first  = fileinput.nextline();         system.out.println(first);       }     fileinput.close();   } }

  1. retrieve filenames , add them in arraylist.
  2. use contains method of arraylist checking user's file name. contains method case sensative.
