Need help with programming a random seat generator.

For my class, I have to programme a random class seat generator. I have already programmed the input of student names. I am having a hard time figuring out how to randomise the name so that it would create randomised groups and show on the screen 
public class MyWorld extends World
{
    private Seat seat1;
    Seat[] seatsArray = {new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),
            new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),
            new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat(),new Seat()};
    private String UserInput ="start";
    private String NumberStudents = "30";
    boolean dataEntered = false;
    public MyWorld()
    {    
        // Create a new world with 1000x800 cells with a cell size of 1x1 pixels.
        super(1000, 800, 1); 
    }

    public void act()
    {
        askQuestions();
    }

    public void askQuestions()
    {
        if (!dataEntered)
        {
            NumberStudents = Greenfoot.ask("How many student names would you like to add?");
            int StudentCount = Integer.parseInt(NumberStudents);
            int i = 0;
            while (i < StudentCount)
            {
                UserInput = Greenfoot.ask("What student name would you like to add?"); 
                seatsArray[i].setSeatName(UserInput);
                i=i+1;
            }
            i =0;
            while (i < StudentCount)
            {
                addObject(seatsArray[i],getWidth()/10,getHeight()/4+40*i);
                i=i+1;
            }        
            dataEntered = true;
        }
    }

Would not shuffling the seats in the array be enough once all the names have been input?

How would I do this? I have only started programming form two months ago The random generator has to generate different randomize the seat each time. Is it also possible to add constraints to the seats? Like if you didn't want a group of students to sit together or a group of students must sit together.

You can sort any Array object, array, using: 
java.util.Collections.sort(java.util.Arrays.asList(array));

The above will.
Is it also possible to add constraints to the seats? Like if you didn't want a group of students to sit together or a group of students must sit together.
It is possible. You will have to be a little inventive it programming that, however.

Where would I add the code? I'm really sorry, I have completely no idea about coding.

After the array is filled.
