How to create a coin flip program

ok well to start off this is my first time on this forum and hopefully im in the right section, im in a highschool computer programing class and would like to do something with my coin flip class over the winter break, i would like to create a program to click a button and it displayes an animation of a coin fliping and then landing on either heads or tails, this is my current code. (oh yeah using blueJ, i dont know if there is another java programing program just thought id mention that just incase.)

Code Java:

public class Coin
{
    // instance variables
    private double value;
 
    /**
     * Constructor for objects of class Coin
     */
    public Coin()
    {
        // initialise instance variables
        value = 0;
    }
 
    /**
     * flip will create a random number between 0 and 1 and store it in value
     *  
     */
    public void flip()
    {
       value = Math.random(); 
 
    }
 
    /** isHeads will return true if the value is less then 0.5
     * 
     *@return true if value < 0.5
     *              false otherwise
     */
    public boolean isHeads()
    {
        if (value < 0.5)
            return true;
        return false;
 
    }
 
        /** istails will return true if the value is greater then or equal to 0.5
     * 
     *@return true if value > 0.5
     *              false otherwise
     */
    public boolean isTails()
    {
        if (value >= 0.5)
            return true;
        return false;
 
    }
 
 
}
