Question

how to make a midlet in which when we click in ok of first page it leads to another page and when we click ok of second page it leads to third page and go on

Answer 1

It seems to me you're doing this for your homework or college assignment.
To do this easily, you can create pages using Canvas class, with each Canvas has its own display layouts. But if the pages are simply text, then why don't you just use an array of string variable to hold the content of the pages? It is easier and less error-prone, since using too many Canvas can produce overhead memory use taken by the MIDlet.
