// Design and implement a class called PairOfDice, with two six-sided

public class P4_4
{

int sides = 6;
// Creates the 2 die objects + and rolls them.
Die Dice1 = new Die(sides);
Die Dice2 = new Die(sides);
Dice1.roll();
Dice2.roll();
System.out.println("You rolled a " +die1 +die2);



// rolls the dice.
public void roll()
{
DiceRoll = (int) (Math.random()*NUM_SIDES) + 1;

}

}[code]

It keeps saying <identifier> expected on the Dice1.roll(); and the next 2 lines
