How can i to make anagram program using two character Arraylists?

Question

this is the Code i have, what should i do ?

It's not even a String. it use Arraylist.

import java.util.ArrayList;
import java.util.Collections;

public class ArrayCheck {
public boolean isAnagram(ArrayList<Character> arr1, ArrayList<Character> arr2) {
   }

}

how do you intend to check if a newly composed string is a valid word? where is your dictionary? — Harmlezz, May 10 '17 at 12:43
Please attempt something. When you get stuck and you don't understand why, you can come back here and ask. — Lexi, May 10 '17 at 12:43
How about you **make** two strings out of the character lists? — OneCricketeer, May 10 '17 at 12:45
@Harmlezz in this case I think an anagram is literally just checking if the length is the same, and characters too but in whatever (random) order. I suspect it's a homework assignment where the exercise provides the method signature — nbokmans, May 10 '17 at 12:47
Actually your question is somehow reduced to [How to compare two ArrayLists?](http://stackoverflow.com/questions/19155283/simple-way-to-compare-2-arraylists). — Sanket Makani, May 10 '17 at 12:50

Ok. I got the impression that you are kind of lost. Hence to get you started here how you may approach your task:

define a dictionary containing all words you will accept.
make sure the newly created string (in your case I guess arr2) is composed of the same characters as the original word (in your case I guess arr1)
if your validation succeeds, lookup the newly created string in your dictionary and if it exists, it is an anagram. Otherwise it is not.

can you please make some code that i can understand with ? – Jeryoz Dimitar May 10 '17 at 14:45 — Jeryoz Dimitar, May 10 '17 at 14:45
