How do I iterate through the files in a directory in Java?

Question

I need to get a list of all the files in a directory, including files in all the sub-directories. What is the standard way to accomplish directory iteration with Java?

Answer 1

Using org.apache.commons.io.FileUtils

File file = new File("F:/Lines");       
Collection files = FileUtils.listFiles(file, null, true);     
for(File file2 : files){
    System.out.println(file2.getName());            
} 

Use false if you do not want files from sub directories.
