为什么我的数组返回的方法无法打印到控制台？

我正在编写一个程序，使用一种方法将.txt文件读入String数组中。但是，当我尝试通过在主程序中打印数组来测试我的方法时，什么也没发生。我创建了一种将txt文件读入数组的方法，现在我试图在主程序中打印此数组以确保其正常工作。

感谢所有帮助，这是我的代码：

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Arrays;
import java.util.Scanner;

public class P4Test {

    public static void main(String[] args) throws FileNotFoundException {
        
        
        
        // have user enter name for file
        Scanner input = new Scanner(System.in);
        
        System.out.println("Enter the name of the file");
                String nameOfFile = input.nextLine();
                
                
                String[] test = readFile(nameOfFile);
                System.out.println(Arrays.toString(test));
    }

    
    public static String[] readFile(String filename) throws FileNotFoundException 
    {
        
        
        
        //read the file 
    
        Scanner file = new Scanner(new File(filename));
        
        // read number of lines inside file
        
        int numString = 0;
        while (file.hasNextLine());
        {
            ++numString;
            file.nextLine();
        }
        file.close();
        
        // now we read the file into a string array
    Scanner keyboard = new Scanner(new File(filename));
    String[] words = new String[numString];
    
    // using a for loop to read in each line to the array
    
    for (int index = 0; index < numString; ++index) {
        words[index] = keyboard.nextLine();
    }
    keyboard.close();
    return words;
    
    
    }
    
    
    
}
