How to do references in Java work?

Help with Java homework?

• The purpose of this assignment is to work with both the File class and recursive program development. You will write a program called FindFile. The program will take two command line arguments. A path string (if there are any special characters in the string, such as a space character, remember to enclose the string in quotation marks) from where the program will start searching. A file name string (only the filename and extension, no path information). Example usage: > java FindFile "C:/Program Files/Java" java.exe The output will consist of a list of all files in all directories under the first command line argument that matches the second command line argument. The full path name will be displayed. Remember to make your program robust so that if the user enters invalid command line arguments messages may be displayed (perhaps some exceptions thrown), but all situations should be handled reasonably gracefully (i.e., messages should explain the problem, and not just crash without any detailed indication of what is wrong). Suggested references: Look at the java.io.File and java.util.ArrayList or java.util.Vector classes in the Java Documentation. In particular, look at In class File: listFiles() getPath() getName() isDirectory(), In class ArrayList or Vector: add() toArray() [Optional] You can also try playing around with filters to allow you to use wildcard characters in your specification of the file name string. Is there anybody out there who can help me with my homework?
