    hello,
    please tell me how to creat an array of an inner cclass;

    class outer 
    {
    ....
    ....
             class inner
              {
                ........
                ........
              }
    }
     
    outer o =new outer();
    outer.inner [ ] i = o.new inner[5];

    For an array, no.
    The correct syntax would be:
    outer.inner[] i = new outer.inner[5];

    However, if you only wanted a single instance of the inner class, something similar to your syntax would work:

    outer o = new outer();
    outer.inner i = o.new inner();

    If you're unsure if something is correct, you can always try it out.

    Something I would recommend is to simply declare the inner class static

    public class Outer
    {
        static class Inner
        {}
    }

    To create a new array it would use the same syntax, but to create a new instance of Inner, you just need to do this:

    Outer.Inner i = new Outer.Inner();
