Стигнах до тук и не мога да я накарам да работи:

import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
import java.util.Calendar;
import java.util.Scanner;
public class TimeForParty {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MM-yyyy");
        LocalDate date = LocalDate.parse(scanner.nextLine(),formatter);
        Calendar calendar = Calendar.getInstance();
        double date1 = calendar.get(Calendar.DAY_OF_WEEK_IN_MONTH);
        if (date1 == Calendar.FRIDAY) {
            System.out.println("Party night! Today is:" + Calendar.FRIDAY);}
            if (date1 == Calendar.SATURDAY){
                System.out.println("Party night! Today is:" + Calendar.SATURDAY);}
                else {
                System.out.println("No party tonight! Today is:" + Calendar.DAY_OF_WEEK_IN_MONTH);}
            }

        }
Който има идеи да помага.
