To change a Day of the week like Monday, Tuesday and so on to integer the use the following code:
public int dayNameComparison(String dayName) {
java.text.DateFormatSymbols objDaySymbol = new java.text.DateFormatSymbols();
String symbolDayNames[] = objDaySymbol.getWeekdays();
for (int countDayname = 0; countDayname < symbolDayNames.length;countDayname++) {
if (dayName.equalsIgnoreCase(symbolDayNames[countDayname])) {
return countDayname;
}
}
return 0;
}
This way when u pass the day as parameter the you will get the output as integer. This output can be used directly in Calendar class as input :
public static void main(String[] args) {
TestMouse testMouse = new TestMouse();
int i = testMouse.dayNameComparison("Tuesday");
System.out.println("" + i);
java.util.Calendar calendar = java.util.Calendar.getInstance();
calendar.set(java.util.Calendar.DAY_OF_WEEK, i);
System.out.println(new java.text.SimpleDateFormat("EEEE").format(calendar.getTime()));//Prints: Tuesday
}
