Find specific file

I want capture a specific file name and the easiest way I found was using a class called JavaXT, based on examples of official site (http://www.javaxt.com/javaxt-core/io/Directory/Recursive_Directory_Search) I tried return the result in my console application across 

javaxt.io.Directory directory = new javaxt.io.Directory("/temp");
javaxt.io.File[] files;

//Return a list of PDF documents found in the current directory and in any subdirectories
files = directory.getFiles("*.pdf", true);

System.out.println(files);

But the returned value always are strange characters like [Ljavaxt.io.File;@5266db4e

Someone could help me to print the correct file(s) name?

When you try to print an array, what you get is its hashcode. Try this if you want to visualize it:

 Integer[] a = { 1, 2, 3 };
 System.out.println(a);

the output will be

[Ljava.lang.Integer;@3244331c

If you want to print element by element, you can iterate through the array. In this case, using a for-each:

for (javaxt.io.File f : files)
    System.out.println(f);

Note that this will print the String returned by the method toString() of the object.

Your files variable is an array. You need

for(javaxt.io.File f:files) System.out.println(f);

Because files is an array, Java will print the array type and the hex hash code.
