T9 is a text input method for mobile phones and other small devices. It replaces the "multi-tap" input method by guessing the word that you are trying to enter. T9 may be embedded in a device by the manufacturer. Note that even if the device supports T9, the Java implementation may or may not use it. Check your documentation for details.

A dialog box is a window that pops up in response to user action to inform the user with a message. E.g. if the user does not save the document and exists the application the window pops up asking if he wants to save the document. This window is the dialog box. Modal Dialog: A modal dialog box disables the window to which it is assigned until the user dismisses the dialog box. E.g. The dialog that gets displayed with "yes"/"no"/"cancel" when you try to exit MS Word without saving the document is a modal dialog box.  A model dialog box is created by calling the doModal() function of the dialog class. This function does not return back control to the caller until the dialog is dismissed. E.g. CDialog dlg; dlg.doModal();  Modeless Dialog: A modeless dialog box is just the reverse of modal. It allows the user complete control of the application which owns it and the user can continue his work without closing the dialog. A modeless dialog box can be created using the Create () command of CDialog class. The Create() call returns as soon as the dialog box is created. Hence the control returns back to the caller and the user is able to continue using the application.
