that's what arrays are for:

int pages[length];

for (int i=0;i<pages.length;i++) {
   pages[i] = i;
}

System.out.println (pages[0]);
System.out.println (pages[1]);
System.out.println (pages[2]);
etc...

sorry, declaration should be:

int[] pages = new int[length];

i need to be able to declare something like

String pages[#] = "Page";

Sorry, what you are describing are facilities you have in script languages, not in compiled languages like Java.
The upside of that is that Java programs run about 100 times faster than script programs.
But you cannot (at this time at least) have both.

would your need be filled by a static class with 2 methods in it.

  StC.setVar( name, value );   // name is a string (fx "Page"+2 ) and var may be a strin or an int or a float or ...
and
  Object n = Stc.getVar( name );  // give you back the variable value for that name in an object

That would be fairly easy to make using a hashmap.

How about declaring an Object to be held in your array,

private class Page {
  public String name;
  public Page(String name) {
    this.name = name;
  }
}

And declare your array as:

Page[] pages = new Page[length];

Then to set the page name use pages[i].name = "hello";

Or, create public get/set methods to access your name.  This approach also allows you to add other items to the page with very llittle effort on  your part!
