My code is :
//my code 
import org.eclipse.core.resources.*;
import org.eclipse.core.runtime.*; 
import org.eclipse.jdt.core.*;
public class ImportSample {
   private IWorkspace myWork=null;
   private IProject   myProject=null;

   public static void main(String[] agr){
        myWork=ResourcePlugin.getWorksapce();
        myProject=myWork.getProject();

  }

}
