Write a Rectangle class.
This class represents Rectangles. Each Rectange has the X and Y coordinates of its center point (as doubles) and its width and height (as double values, too). No other values should be stored! This means no area, no perimeter!
The class should have the following constructors and methods:
1. a constructor that takes X, Y, width, and height as arguments;
2. a constructor that takes only width and height as arguments;
3. a default constructor;
4. a method setCenter that takes X and Y as arguments;
5. a method setWidth that takes a width value;
6. a method setHeight that takes a height value;
7. a method getX that returns the X coordinate;
8. a method getY that returns the Y coordinate;
9. a method getWidth that returns the width value;
10. a method getHeight that returns the height value;
11. a method getArea calculates the area of the rectangle and returns it;
12. a method getPerimeter it calculates the perimeter of the rectangle and returns it;
13. a method toString that creates a String that includes the X, Y center coordinates, width, and height, and returns the string. This method does not use System.out.println() itself. It returns a String value to the caller.
Write an application (RectangleTest.java) to test your Rectangle class.
Your Application should test all the constructors and methods.
I need a submission of Both files: Rectangle.java and RectangleTest.java
please email me at T45russ@aol.com if you can write this program. I have been trying so hard and can't make it work. Thanks to all.

Hi guys, I think I'm going to lose my mind with this, I cant make my chunked transfer manager to work right.
The problem I'm having is that reading the amount of data specified in the chunk-size, I end up having the next chunk size inside the body, so, when I call the next getchunksize, it fails.
The first call to getChunkSize() works great and I get the size value as expected.
The BufferedReader is connected to the sock
<br />
s = new Socket(connectTo, portNum);<br />
sIn = new BufferedReader(new InputStreamReader(s.getInputStream()) );<br />
Thanks a lot guys, I hope any of you understands what's going on...
<br />
private String processChunked(BufferedReader sIn, String newData) throws IOException {<br />
<br />
newData += LINEBREAK;
<br />
int size = 0;<br />
String body = new String();<br />
<br />
size = getChunkSize(sIn);<br />
<br />
while(size > 0) {<br />
<br />
body = getChunkData(sIn, size); <br />
size = getChunkSize(sIn);<br />
<br />
newData += body;<br />
body = "";<br />
<br />
}<br />
<br />
return newData;<br />
<br />
}<br />
<br />
private String getChunkData(BufferedReader sIn, int lenght) throws IOException {<br />
<br />
int val = 0;<br />
String res = new String();<br />
char chr = ' ';<br />
<br />
for(int i= 0; i<lenght; i++)="" {<br="" mode="hold" /> <br />
val = sIn.read();<br />
<br />
if(val == -1)<br />
break;<br />
<br />
chr = (char)val;<br />
<br />
res += Character.valueOf(chr).toString();<br />
<br />
}<br />
<br />
<br />
return res;<br />
}<br />
<br />
private int getChunkSize(BufferedReader sIn) throws IOException {<br />
<br />
char chr = ' ', prvChr = ' ';<br />
int val = 0;<br />
String tmpSize = new String();<br />
int size = 0;<br />
int readed = 0;<br />
<br />
do {
<br />
prvChr = chr;<br />
val = sIn.read();<br />
<br />
if (val == -1) {<br />
break;<br />
}<br />
<br />
readed++;<br />
<br />
chr = (char) val;<br />
<br />
tmpSize += Character.valueOf(chr).toString();<br />
<br />
} while (prvChr != '\r' && chr != '\n');<br />
<br />
<br />
if(tmpSize.indexOf(";") != -1) {
tmpSize = tmpSize.substring(0, tmpSize.indexOf(";"));<br />
}<br />
<br />
tmpSize = tmpSize.trim();<br />
<br />
try {<br />
size = Integer.valueOf(tmpSize, 16); <br />
} catch (NumberFormatException e) {<br />
size = 0;<br />
}<br />
<br />
return size;<br />
}<br />

For more details and orderliness,here gives items to show what I want a program A could do these:
1.Supervise how much memory the program B consumed.If the program B was running and allocated memory exceeded the speciafied number,then report back to screen.
2.Restrict the priority of accessing the files out of its directory/folder to program B.Avoid running the dangerous code like system("reboot") from programs.
3.Kill the Process B if there includes any code lead to never finish running.e.g while(1){}.Of course,if a legal program run out time will be also killed.
4.How can I capture these above return messages,e.g Runtime error,stack overflow,Memory Limit Exceed.So much information just for users.
Note:This is very similar to a online judge system.
Thanks In Advance.
no cross no crown.

as long as your "judge" doesn't go inspect the binary code directly in the .class file, i don't really think most of your points can be done.
btw: No need to REPOST !!! this is a forum, not a chat, so please be patient

Why would you use java to compile C/C++ ?¡
And for what you want to do (full control over the compilation) you should resort to something like make and predefine each and every step in the process, and calling the makefile in your exec(...)
Don't you also love the code?

I have been tasked with creating a thumbnail page that when a member clicks on the thumbnail it opens the image in a new window with all bars disabled, right clicking disabled, no status bar, no ability to resize, etc. The window should be 350x250. We want to do this without having to create any extra pages beyond the thumbnail page. I have a script already that opens the images in a new window with everything but right clicking disabled/gone. I know most people say don't disable right click, but it is on a secured members only site and we are showing possabilities for our membership to use as the mast heads for their new websites and we don't want them to be able to save the images.

I am developing some web pages in which iam using a java applet. so far the intended user are supposed to be using Internet Explorer 7. the problem i am facing is that when i press the tab key within the applet. the control get transferred to new tab position in the web page outside the applet and i have to click back to the applet to get control again transferred to the applet.
i want to restrict the control of tab so that when tab is pressed within the applet the tab should not move to next tab position in the page and remain confined within the applet.
Can someone please help me how can i achieve this and whether i have to do coding for it in the applet or in the web page...so that within the applet the Internet Explorer tab control should remain disabled..
