→"Add Student" Command
Please do this part, after the view, Jface viewer and Editor view is added and working properly.<br/>
1. Implementing the execute method of the command handler class:<br/>
This code will get access to the page and creates an empty editor input (sending it the id of string "0" indicating that it belongs to no student), then tries to open the editor with that input id.
<code>AddStudent.java </code>
