Aaah i see now , but if i don't implement the class with threading(which i'm trying to avoid just because it would add more complexity ), what would be a good mechanism to call the repaint method ?
btw thanks for your patience, and sorry for all the noobie questions but my deadline is closing in fast and i haven't even gone into the difficult part of the project

If you don't want to use threading then simple use canasVariableName.repaint();. I think that's what you mean but I'm not sure.
If you do want to use threading then this method is the simplest way.

You had an answer to the same question yesterday. If you want it in java then I suggest you rewrite the C# code into java rather than being lazy and asking for someone else to do it.

class jumping{
public static void main(String[] args){
int b,c;
float a;
b = 8;
c = 2;
test:
{
a = b/c;
System.out.println("a first is "+a);
while(a<=10){
b++;
System.out.println("b in continue is "+b);
if (b==12)
{
break test;
}
System.out.println("a final is "+a);
continue test;
}
}
}
}
i need final value of a is 6. but i can't?
can you solve this?
there are error in "continue test" statements, it give not a label?
i need there code jump to label test like goto in C++?
Kindly help me????

why not just make test into a function or method and invoke it, im not sure what your code is supossed to do, but if it's supossed to continue executing untill b is 12, i've written an example :
class jumping{
public static void main(String[] args){
int b,c;
float a;
b = 8;
c = 2;
test(a,b,c);
}
public void test(float a, int b, int c)
{
for( ; ; ){
a = b/c;
System.out.println("a first is "+a);
while(a<=10){
b++;
System.out.println("b in continue is "+b);
if (b==12)
{
System.out.println("a final is "+a);
return;
}
}
}
}
}
ps : ident your code, it's very difficult to read otherwise, and use the code block
ps2 : someone should disbale smileys in the code block

class jumping
{
public static void main(String[] args)
{
int b,c;
float a;
b=8;
c=2;
test:
{
a=b/c;
System.out.println("a first is" +a);
while(a<=10)
{
b++;
System.out.println("b in continue is " +b);
if(b==12)
{
break test;
}
System.out.println("a final is" +a);
continue test;
}
}
}
}
i want if b not equal to 12 then "a final is" is print. and b increase and also a is but it not?
"kindly help me in java for using label/jump like goto in c++"

have you tried my code ? that's basically what it does

thanks. that is ok..
but it's not good solution for my problem.
ok, i tell all thinks....
i develop a math program where a loop run apporoximat 800000 time and finaly value is came. in c++ there are goto statements and control jump to backword or forwared where we need. like that i need jump my code if my condition false and if true the loop exit.. so i can't use function.
and it's a reason i send my code like that...
so if u do please help me..

The goto statement is bad. When ever you call goto in a program a bunny will stub its toe. You can't be nasty to a fluffy bunny's toe can you?
Loose the goto and learn to love and embrace methods and loops.#

Start off by taking your medication, put on your glasses and then read what you have written. What is there in the above that anyone can possibly help you with?
Try something and when you have a problem with your homework ask a sensible question that will elicit help.
No one is going to do your homework.

Hy guys ! i'm having a problem getting my tcp server applet on it's feet, the problem is that it doesn't get past instantiating a socket, if i instatiate it with port nr 80 it throws an exception ( Address already in use: JVM_Bind ), with other ports it just locks up at the "binding port" part
ServerSocket server;
int port= Integer.parseInt(portNumber.getText());
status.setText("Starting server..\n");
try {
status.append("Binding to port " + port + ", please wait ...\n");
server = new ServerSocket(port);
} catch (IOException ioe) {
status.append("EROARE la creearea socketului\nEXCEPTIE:
"+ioe.getMessage()+"\n");
return;
}
does anybody have a clue why this happens?

i'm uploading the server class and test web page if it will help sort this out
here it is : [url]http://uploading.com/files/XQ0TGHPT/server.rar.html[/url]

I couldn't say why a port might lock up, but if you're using windows you could run the "netstat -a -b" command with arguments to determine if the ports you are selecting are in use. The -b parameter will also tell you what process is using the port in question.
At a minimum, that will tell you if a port you are trying to use is available or not. If you have an appserver installed and running, (or even skype), one of them may be using port 80.

You might have something else on port 80?
This is the main port used by HTTP, so if you've got another web-service it may well be in use.
Try running it up pointing to a DIFFERENT port and see what happens.

allready tried , it locks up at the ServerSocket instantiation, and starting today it lock up on 80 too, i have absolutelly no clue what i'm doing wrong
