Hi! Is there a possibity of growing or shrinking java-arrays at runtime similar to CObArray in MFC (with Add() or Remove()...) ?
After writing
int array[] = new int[5];
how can I change the size of this array?
Thank you.

Why not use Vector?

Use the Vector class!

To resize your array you need to create a new one and then copy with System.Arraycopy
It's the same a realloc in c, but you have to write down the code.
realloc(in[] a, int size)
{
int[] newArray = new in[size];
System.arraycopy(a,0,newArray,0,a.length());
a = newArray;
}

If you have an unknown number of items an array probably isn't your best choice of container. There's a whole subtree of container classes in the java libraries, which one will most suit depends on the way you are accessing the elements. You should consider Vector (if you really need to acces by index) or one of the List classes, e.g. ArrayList if your processing is usually sequential.

Java i capable of overload function names when there are diffrent in parameters. ex.
class DataRenderer {
void draw(String s) {
. . .
}
void draw(int i) {
. . .
}
void draw(float f) {
. . .
}
}
BUT what if you want the reverse;
class DataRenderer {
void String draw() {
. . .
}
void Integer draw() {
. . .
}
void Document draw() {
. . .
}
}
The beautiful language C++ has no problem whit this. Is it because all objects inherit from Object ??

What you posted is not the beautiful language C++! Your draw methods have two return types, void and some other class.
Secondly, return types are not considered in overload resolution. If the spurious 'void' is removed from your function signatures, they are still invalid. The standard does allow covariant return types in overridden functions, but that's a different thing altogether.

I have an applet which has more then one class file, There is no problem to control public function in the applet from javascript when the functions are in the main class, but when I try to call a function which is located in another file, it gives me an error.
Any idea ????
|
|
|
|
|
Can you give me full detail of problem.
upto my knowledge it is due to that you have to declare
the instance variables of the other files and then use that
instance variable to access the function u want by using the
scope operator or the dot operator.
if u can give me more detail of the problem i can help u.
Good luck
Rajiv

Is your "CODEBASE" right? Remember it will have to download the other .code file (unless you use a jar) so it needs to know where to look.
