Compare dates in java

I am getting two dates from server in yyyy-MM-dd format. I have to compare between these two dates. I used compareTo() method to compare two dates. what is more easier way to compare two dates assuming my server will always return not null value in yyyy-MM-dd format?

Define the method

void compareTwoDates(String startDate, String endDate){
        switch(startDate.compareTo(endDate)){
            case -1:
                //START DATE IS BIGGER THAN END DATE
                System.out.println(endDate+" IS BIGGER THAN "+startDate);
                break;
            case 0:
                //BOTH DATE ARE SAME
                System.out.println("SAME DATE");
                break;
            case 1:
                //END DATE IS BIGGER
                System.out.println(startDate+" IS BIGGER THAN "+endDate);
                break;
        }
    }

call the method using following way

compareTwoDates("2012-05-06", "2012-04-08");
compareTwoDates("2012-04-09", "2012-04-09");
compareTwoDates("2012-04-09", "2011-05-10");

Use methods Date.before() and Date.after()
