                    Unknown program behaviour

                    I have written another program which is doing almost the same thing. It reads the drawrects() method but when it reaches the 2nd and 3rd method it shows null , null. I modified the input file by replacing colours instead on names ..andrew etc... Why is this null coming while reading 2nd and 3rd method. If you will run the program you will come to know what is happening.

                    Code:
                    import java.io.*;
                    ...

                          File Managment Functions

                          Hi,
                          I need to develop the functions below for a server in Java. Is there any package or class that I can use ?
                          I just had a look at one namely...
                          com.mindbright. net.ftp.
                          Can you guide me about developing these functions below:-

                          1) Retrieve file from server
                          2) Add, edit, delete a file from server.
                          3) upload / download file from server
                          4) Logon and version control

                          Regards...

                                    Hi,

                                    I am trying to write a Java program to plot rectangles with different colors side by side non overlapping but unfortunately I am unable to do that as of now.
                                    Suppose I want to create 3 rectangles:-
                                    100 - 200
                                    200 - 300
                                    300 - 400

                                    I want to have 3 rectangles non overlapping and adjacent to each other with 3 different colors. I am new to Java so don't know howto do that ?!
                                    I would appreciate...
