array required, but ArrayList<String> found
java
Solution
You need to use the `get()` method to get the element at a particular index from an `ArrayList`. You can't use `[]` to get the element at a particular index, in an arraylist. Its possible only for arrays and your `files` is not an array, but an ArrayList.
System.out.println( i + ". Ist: " + files.get(i));
Also, the condition in your `for` loop is a bit off. `files.size() <= i` is `false`, and therefore, it doesn't enter the `for` loop at all.
Change it to something like this.
for(int i = 0; i < files.size() ; i++){
Problem
I have a ruby backround and im new to java i wrote a basic programm but somehow i get a error i cant fix! My code: ``` import java.util.ArrayList; public class Music { private ArrayList<String> files; public static void main(String args[]){ Music a = new Music(); a.addFile("Chasen Paper"); a.addFile("Mama"); a.addFile("Hell Yes"); a.removeFile("Hell Yes"); } public Music(){ files = new ArrayList<String>(); } public void addFile(String filename){ files.add(filename); } public void returnFiles(){ for(int i = 0; files.size() <= i; i++){ System.out.println( i + ". Ist: " + files[i]); } } public void removeFile(String filename){ System.out.println("Vorher gab es " + files.size() + " Dateien"); files.remove(filename); System.out.println("Jetzt gibt es " + files.size() + " Dateien"); } } ``` When i try to compile it i get somehow this error: What did i wrong? Thanks! ``` Music.java:26: error: array required, but ArrayList<String> found System.out.println( i + ". Ist: " + files[i]); ```
