Zig Zag motion

On clicking the start button

Changed the ball's color to hgb

Using stop button

Using java swings ,I tried to make the zig zag motion  of a ball when it strikes the boundaries of the rectangle on clicking the "start" button It has a "stop" button and another button to change the ball's color to HGB.
The code is quite simple .First of all create a frame using JFrame as follow

JFrame a = new JFrame("Zig Zag");

After declaring its attributes ,create a class  say zigzag which inherits JPanel and another class say bounce which inherits JPanel and an interface ActionListener.Now declare an object of class bounce say bounce b;

After that declare the constructor zigzag() as follow

Before clicking the start button

b = new bounce();
JButton startButton = new JButton("Start");
JButton hgbButton = new JButton("Change color to HGB");
JButton stopButton = new JButton("Stop");
JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(new BoxLayout(buttonPanel, BoxLayout.X_AXIS));
buttonPanel.add(startButton);
buttonPanel.add(hgbButton);
buttonPanel.add(stopButton);
 stopButton.setText("Stop now !");
this.setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
this.add(buttonPanel);
this.add(b);

Now,for the start button set animation to true and for stop button set animation to false .To change the color to hgb use :

b.setBallColor(Color.getHSBColor(TOP_ALIGNMENT, TOP_ALIGNMENT, TOP_ALIGNMENT));

 Now,inside the class bounce define the radius,diameter ,velocity across Xaxis and Yaxis , paint()..

Simple ChatBot using C++

I tried to make a chat with a bot ..after being inspired by a samsung app -Palingo .
This is a C++ prohram which is  konsole based.
It takes an input from user and the response is random .It includes header files like iostream,cstdlib,string and ctime .
I made a string -response having the script .And an infinte while loop to proceed the script .
It is a simple c++ program ,more improved version will be provided soon ..........
Mail me to obtain its source code and if interested to make chatbot using swings .
