program called CrapsGame that implements a variation of a popular dice game played in casinos called craps

i wrote the method under public static void main(String[] args) please help me write it under public static int rollDie(). I do not know how to write it under the public static please help.

Write a separate method to accomplish this function, and call it rollDie() to return the randomly generated number.

public static int rollDie()

Call the rollDie() method twice to generate two random numbers for two dice. Check the sum of the two dice. If the sum is 2, 3, or 12 (called craps), you lose; if the sum is 7 or 11 (called natural), you win; if the sum is another value (i.e., 4, 5, 6, 8, 9, or 10), a point is established.
