Java Program To Simulate Rolling Of Two Dice?

Write a program to simulate the rolling of two dice. The program should use Math.random (google how to use Math.random if needed) to roll the first die and should use Math.random again to roll the second die. The sum of the two values should then be calculated your program should roll 50,000 times. Use a single dimensional array to tally the numbers of times each possible sum appear(the possible values are 2 through 12, think about why?). Print the results in a tabular format.

Here's the code I'm working on so far:

public class RollingDice{
public static void main(String[] args){
int die1;
int die2;
int roll;
die1 = (int)(Math.random()*6) + 1;
die2 = (int)(Math.random()*6) + 1;
roll = die1 + die2;
System.out.println("The roll of the first dice is: " + die1);
System.out.println("The roll of the second dice is: " + die2);
System.out.println("Your total roll is: " + roll);
}
}

What am I missing at this point, and what parts did I do wrong to change it?
