Anybody now how to do Insertion sort in Java ( JDK 1.2 )
|
|
|
|
|
Must it be Insertion sort? Why don't you use Quicksort.
If you want I'll send you my little Quicksort-Wrapper-Class... 
E-Mail me...

It entirely depends how your data is likely to be stored. If you want a dense array there are binary chop search routines supplied in the "Arrays" class (and use System.arrayCopy). You should also take a good look at the TreeMap or TreeSet clases one of which will probably handle it all for you.

I was successful implimenting drag and drop from a JTree to Native NT system, used David Woods code he posted here to give me a leg up, thanks Dave, helped alot. I still need to determine the path the object was dropped into the native system though, and have not found a way to pull it out. Anyone have some suggestions ?

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.
