Unexpected Token of While on For Loop

I'm trying to add images from a folder to an array list however I'm getting an "unexpected token" at the beginning of the for loop, a "cannot resolve symbol 'length' and "identifier expected" on the incrementing of the control variable.

I'm using Intellij as my IDE

import java.io.File;
import java.util.ArrayList;
import java.util.List;

public class Cards {
    File path = new File("/images");
    List imageCollection = new ArrayList();
    File [] files = path.listFiles();
    for(int i = 0; i < files.length; i++){
        if (files[i].isFile()) {
            imageCollection.add(files[i]);
        }
    }
}

I think you want the code to be within a method. Perhaps a constructor, or the main method, I'm not sure what you are trying to accomplish.

Java also allows you to just place code in a block within a class, but I assume that isn't what you want in this example.
