java - Vocab learning program not working properly -

so code, , it's meant give random word list, have user input meaning that's in external text file, , if it's correct, removes word list otherwise keeps word , adds missedword list. problem words aren't getting removed list, , can't seem print arraylist. can me problem? also, there improvements can make code? thank of help.

import java.io.*; import java.util.*;  public class wordlist1 { public static void main(string[] args) throws ioexception{     boolean fart = true;      filereader fr = new filereader("wl1.txt");     bufferedreader br = new bufferedreader(fr);      scanner console = new scanner(system.in);      arraylist wordarray = new arraylist();     arraylist missedwords = new arraylist();      string input, stringarray[] = new string[2], answer;      while((input=br.readline())!=null){         stringarray = input.split(" ");         wordarray.add(stringarray);     }      while(fart){         stringarray = (string[]) wordarray.get((int)(math.random()*(wordarray.size())));         system.out.println(stringarray[0]);         answer = console.nextline();         if(answer.equalsignorecase(stringarray[1])){             system.out.println("correct");             wordarray.remove(stringarray[1]);         }         if(!answer.equalsignorecase(stringarray[1])){             system.out.println("incorrect, " + stringarray[1]);             missedwords.add(stringarray[0]);         }         if(answer.equalsignorecase("escape")){             fart = false;             system.out.println(missedwords);         }         if(answer.equalsignorecase("print"))             system.out.println(wordarray);     } } 

}

system.out.println(wordarray) going call .tostring() on arraylist, gives information reference, not data inside list. need write out each element in list rather list object itself:

system.out.println("words in array:"); (string eachword : wordarray) {   system.out.println(eachword); }

now, works if you've defined list list of strings. definition creates list of java object:

arraylist wordarray = new arraylist(); 

it's better practice specify type of elements go in list. done using generics:

arraylist<string> wordarray = new arraylist<>(); 

that assumes wordarray list of words, code adds entire array wordarray list. give you? think want this:

while((input=br.readline())!=null){     stringarray = input.split(" ");     // add each word, not array     wordarray.addall(arrays.aslist(stringarray)); }

your problem words not getting removed similar problem. arraylist holds array of strings, you're trying remove single string. call .remove() not find string in arraylist.
