Replit.com

By default, Replit uses Main as the main class. To change the Main class name to a class name of your choosing, create a new file within replit and call it .repl. Within the file type the following:

run="sh main.sh"

javac NewClass.java  # whatever that file is java NewClass

Lastly, make sure that the Main class is label correctly! In this instance it will be called NewClass.

Another method that you may find useful within replit is that you can create different programs and have them execute on the Main.java page.

public class Main {
  public static void main(String[] args) {
    ProgramOne.main(args);
    ProgramTwo.main(args);
    ProgramThree.main(args);
  }
}

Example of this in use can be found here. Use this format for Assignment 2 and all future programs where you are asked to create two different programs.

import java.time.LocalDate;
import java.time.LocalTime;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.time.Period;

public class DateTimeExample {

    public static void main(String[] args) {
        printLocalDate();
        printLocalTime();
        printLocalDateTime();
        printFormattedDateTime();
        calculatePeriod();
    }

    // Method to demonstrate LocalDate
    public static void printLocalDate() {
        LocalDate date = LocalDate.now();
        System.out.println("Current Date: " + date);
    }

    // Method to demonstrate LocalTime
    public static void printLocalTime() {
        LocalTime time = LocalTime.now();
        System.out.println("Current Time: " + time);
    }

    // Method to demonstrate LocalDateTime
    public static void printLocalDateTime() {
        LocalDateTime dateTime = LocalDateTime.now();
        System.out.println("Current Date and Time: " + dateTime);
    }

    // Method to demonstrate formatting LocalDateTime
    public static void printFormattedDateTime() {
        LocalDateTime dateTime = LocalDateTime.now();
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        String formattedDateTime = dateTime.format(formatter);
        System.out.println("Formatted Date and Time: " + formattedDateTime);
    }

    // Method to demonstrate Period
    public static void calculatePeriod() {
        LocalDate startDate = LocalDate.of(2020, 1, 1);
        LocalDate endDate = LocalDate.now();
        Period period = Period.between(startDate, endDate);
        System.out.println("Period between " + startDate + " and " + endDate + ": " + period.getYears() + " years, " + period.getMonths() + " months, and " + period.getDays() + " days");
    }
}
