Java Programming

Okay: heres the question::

Create a lottery game application. Use the Math.random() method to generate three random numbers, each between 0 and 9. Allow the user to guess 3 numbers. Compare each of the user's guesses to the three random numbers. Display how many matched, and how much the user has won.

Any one matching : $10
Two matching: $100
Three matching, not in order: $1000
Three matching, in exact order: $1,000,000
No matches: $0

I just can't wrap my head around how to go about this, its part of a chapter revolving around loops (mainly if loops) and using switch cases. This is the code i have so far, which isn't much.

import java.util.Scanner;

public class Lottery {
public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

int ranNum1;
int ranNum2;
int ranNum2;
int guess1;
int guess2;
int guess3;

ranNum1 = (int)Math.floor(Math.random() * 10);
ranNum2 = (int)Math.floor(Math.random() * 10);
ranNum3 = (int)Math.floor(Math.random() * 10);

System.out.println("Enter your first number: ");
guess1 = sc.nextInt();
System.out.println("Enter your second number: ");
guess2 = sc.nextInt();
System.out.println("Enter your third number: ");
guess3 = sc.nextInt();

Any help would be appreciated, thankyou.
