hello I need help filling in the red areas in JAVA please!

public class GameSimulator { private int tries; private Die di, d2; private int wins; private int losses; /*** Construct a simulator object for die games. @param numSides the number of sides on the die @param numTries the number of times to run the simulation, public Game Simulator(int numSides, int numTries) Runs a single die simulation.
