Language/Type: Java recursion file input
Related Links:

Write a recursive method named crawl that accepts a string for a file or directory name as a parameter and prints information about that file or directory. If the name represents a normal file, just print its name. If the name represents a directory, print its name and information about every file/directory inside it, indented by 4 spaces at each level. For example, the call of crawl("course") might print the following information about your course directory:

course
    handouts
        lecture-schedule.xls
        syllabus.doc
    homework
        1-gameoflife
            GameOfLife.zip
            life.h
            life.java

Show the files in a given directory sorted in alphabetical order. (You may want to use the Arrays.sort command to help you with this.)

Constraints: Your method must be recursive, though you may use a loop to help you as appropriate.

Method: Write a Java method as described, not a complete program or class.
