Using Int In java GUI

Question

What can I do to appear a dialog box asking the user to enter the number of students... (the highlighted part)![enter image description here][1]

    JOptionPane.showMessageDialog(null, "Welcome");
    JOptionPane.showMessageDialog(null, "Students mark Input Project");
    JOptionPane.showMessageDialog(null, "In this program the user is going to enter the students name, class and marks.Then the program is going to output several information about each student.");
    JOptionPane.showMessageDialog(null, "Class Information must be entered as the name of the class, the subject and the number of students");
    String nameofclass = JOptionPane.showInputDialog("Enter the name of the class");
    String nameofsubject = JOptionPane.showInputDialog("Enter the subject"); 
    int numberofstudents =Integer.parseInt("Enter the number of students");
    JOptionPane.showMessageDialog(null,"Class Students Information");
    JOptionPane.showMessageDialog(null,"You must enter the name, surname and " + nameofsubject + " marks for each and every student in class "+ nameofclass);
    StLuciaClassrooms theclass =new StLuciaClassrooms(nameofclass, numberofstudents);
    theclass.enterInformation(numberofstudents);//

The image is missing. What does this have to do with either JavaScript or JEE? — Andrew Thompson
