Question

I was wondering if I can get an output like this with Java

That has to work under Linux, Windows and Mac; and if it’s possible I prefer not to use Runtime.exec().

Answer 1

I think you can use the metadata of a File object to get anything you need. Check the following link:

http://docs.oracle.com/javase/tutorial/essential/io/fileAttr.html

Example:

Path file = ...;
BasicFileAttributes attr = Files.readAttributes(file, BasicFileAttributes.class);

System.out.println("creationTime: " + attr.creationTime());
System.out.println("lastAccessTime: " + attr.lastAccessTime());
System.out.println("lastModifiedTime: " + attr.lastModifiedTime());

(This example was taken from the link I provided).

Hope this helps you

Checking the Java API, I find out that the data you need (size, attributes, etc.) are accesible through the File class methods. Check: http://docs.oracle.com/javase/7/docs/api/java/io/File.html

Notice that linux and mac are both Unix-like systems, and windows is not. Therefore, you won’t be able to get all the file attributes you can expect to get on linux or mac in windows… but you can get the most important values
