Want to get day of a week as a string, But giving wrong day

Want to get day of a week as a string, But giving wrong day

I tried to get the day as a string by using the following code. But it
returns wrong string. Can I fix it with this code.
private String getDayOfWeek(int value){
String day = "";
switch(value){
case 1:
day="Sunday";
break;
case 2:
day="Monday";
break;
case 3:
day="Tuesday";
break;
case 4:
day="Wednesday";
break;
case 5:
day="Thursday";
break;
case 6:
day="Friday";
break;
case 7:
day="Saturday";
break;
}
return day;
I implements it as
Calendar c = Calendar.getInstance();
String dayOfWeek = getDayOfWeek(Calendar.DAY_OF_WEEK);
System.out.println(dayOfWeek);
Thanks in Advance
