import java.util.List;




public class Pics {
    List<String> results = new ArrayList<String>();


    File[] files = new File("/path/to/the/directory").listFiles();
    //If this pathname does not denote a directory, then listFiles() returns null. 

    for (File file : files) {
        if (file.isFile()) {

In Java, only the declarations of variables can be written directly in class but in case you want to write some logic, use the functions. This is what the definition of class says: wrapper for data and functions that act on that data. Additionally use constructors to provide wrapper to initializations.

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

public class Pics {
    List<String> results;
    File[] files = null;
    public Pics() {
        results = new ArrayList<String>();
        files = new File("/path/to/the/directory").listFiles();
    }

    //If this pathname does not denote a directory, then listFiles() returns null. 
    public void testFunction() {
        for (File file : files) {
            if (file.isFile()) {
                results.add(file.getName());
            }
        }
    }
}

This for loop must be inside some method :

for (File file : files) {
    if (file.isFile()) {
        results.add(file.getName());
    }
}
