hi there,

in my application i have to wait for an event..( data read from socket )
but i do not want the page waiting for that amount of seconds until it can display the page in stead i want some sort of event so i can process the data further..
whenever the data has been read..
is this possible and if so how..??

thanks,
robert

Hi michael,
an api is just a subscription of a method
and how to use this method in your application
robert

hi all,
to my knowledge a string literal will never be
eligible for gc is this true??
could someone clear this up for me thanks..
Robert
example
String s; public class Test{ public void method(){ s = "hallo"; s = null; //1 not after 1 also not after scope of method } public static void main(String args[]){ String s1 = "test"; s1 = null; //2 not after 2 new Test().method(); } }

Hi,
why not use a frame

Hi Cristoffer,
an inner class my extend another class or implement an interface
or nothing (implicit Object)
robert

hi there,
i still do not get it...
id got another example..
could someone make this clearup the question
why this parent's method is invoked
and not the child version..
also when i say Parent p1 = new Child();
p1.dostuff();
will invoke the parent's method..
or is this because the static method belongs to
the class object rather than the instance..??
thanks,
Robert
public class StaticOverridingTest { public static void main(String s[]) { Child c = new Child(); c.doStuff(); // This will invoke Child.doStuff() Parent p = new Parent(); p.doStuff(); // This will invoke Parent.doStuff() p = c; p.doStuff(); // This will invoke Parent.doStuff(), rather than Child.doStuff() } } class Parent { static int x = 100; public static void doStuff() { System.out.println("In Parent..doStuff"); System.out.println(x); } } class Child extends Parent { static int x = 200; public static void doStuff() { System.out.println("In Child..doStuff"); System.out.println(x); } }

Hi
try
hand.push(card)
Robert

Hi,
if you are planning to use webstart you have to make use of a webserver so the url you type
must be something like http:\\localhost:8080\webstartTest.jnlp
you can use tomcat for example..
otherwise just use a applet
Robert

thanks Jamal
and Rob good question

Hi ,
i think the question is about the increment operator...
i would expect it started from 1
apparently in the for statement there is no difference between
++i
and i++
could someone explain this please??
Robert

Hi ,
same answere as in other thread...
the sleep sleeps for x mili seconds
so sleep(500) sleeps for at least half a second..
Robert

Hi,
sleep(1800) is 1.8 second
sleep(30000) 30 seconds
or could be a bit more see the api
Robert

hi,
just download it from the java website
and adjust your webserver add the mimetype jnlp
place a .jnlp file on your server for example see
the sun's website..
that should do the trick..
you can use a normal main application
hope this helps ,
Robert

hi,
sounds to me you got a nullpointerexception
maybe when you add some code somone can point out the problem to you
