I need to exclude Saturdays and Sundays from this program that shows dates of every 15 days

I'm trying to make a program that shows dates of every 15 days.

import java.time.*;
import java.util.Scanner;
;

public class test{
    public static final String ANSI_RESET = "\u001B[0m"; //ANSI Color code   //only for colored text. 
    public static final String ANSI_YELLOW = "\u001B[33m"; //ANSI Color code //only for colored text.
    public static final String ANSI_RED = "\u001B[31m"; //ANSI Color code    //only for colored text.
    public static final String ANSI_GREEN = "\u001B[32m"; //ANSI Color code  //only for colored text.
    public static final String ANSI_BLUE = "\u001B[34m"; //ANSI Color code   //Only for colored text.
    public static final String ANSI_PURPLE = "\u001B[35m"; //ANSI Color code //only for colored text.
    public static final String ANSI_CYAN = "\u001B[36m"; //ANSI Color code   //only for colored text.
    public static final String ANSI_WHITE = "\u001B[37m"; //ANSI Color code  //only for colored text.



    public static void main(String[]args) {

        System.out.println(ANSI_YELLOW + "Bi-Weekly Calculator" + ANSI_RESET); //Introduction
        try {
            Thread.sleep(2000); //Pause for 2 seconds
        } catch (InterruptedException e) {
            throw new RuntimeException(e);
        }

        System.out.println(ANSI_YELLOW + "This calculator will only show dates for the next 12 months." + ANSI_RESET);
        try {
            Thread.sleep(2000);//Pause for 2 seconds
        } catch (InterruptedException e) {
            throw new RuntimeException(e);
        }

        Scanner scanner = new Scanner(System.in); // Date input from user
        System.out.print(ANSI_RED + "Enter Date : " + ANSI_RESET);
        String INPUT_DATE = scanner.next();

        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) { //Line 37 to 41 for pausing the code for 2 seconds.
            throw new RuntimeException(e);
        }


        LocalDate today = LocalDate.parse(INPUT_DATE);
        System.out.println("\n"+today);
        System.out.println();
        System.out.println(today.plusDays(15)+"\n"); //days added to input date.
        System.out.println(today.plusDays(30)+"\n");
        System.out.println(today.plusDays(45)+"\n");
        System.out.println(today.plusDays(60)+"\n");


    }
}

The program takes input from the user and adds 15, then 30, then 45, and so on. I need o remove Saturdays and Sundays from this program as I'm actually making this program for the every 15 day pay for someone.

I didn't find any good solution on google, and I'm kinda new with java. I'm using JDK 20.0.1 and IntelliJ IDEA as IDE.

tl;dr

package work.basil.example.time;

import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.ZoneId;
import java.util.EnumSet;
import java.util.Set;

public class FifteenDays
{
    public static void main ( String[] args )
    {
        ZoneId z = ZoneId.of ( "Africa/Tunis" );
        LocalDate today = LocalDate.now ( z );

        int daysToJump = 15 , jumps = 5;  // Jump to 0, 15, 30, 45, 60 days out.
        Set < DayOfWeek > weekend = EnumSet.of ( DayOfWeek.SATURDAY , DayOfWeek.SUNDAY );
        LocalDate localDate = today;
        for ( int jumpIndex = 0 ; jumpIndex < jumps ; jumpIndex++ )
        {
            int daysJumped = ( daysToJump * jumpIndex );
            localDate = localDate.plusDays ( daysJumped );
            if ( weekend.contains ( localDate.getDayOfWeek ( ) ) ) continue;
            System.out.println ( "jumpIndex: " + jumpIndex + " | daysJumped: " + daysJumped + " | localDate = " + localDate );
        }
    }
}

Details

> LocalDate today =

To capture the current date, you need a time zone. If omitted, your JVM’s current default time zone is implicitly applied. Understand that for any given moment, 👉 the date varies around the globe by time zone; tomorrow in Tokyo Japan is simultaneously yesterday in Toledo Ohio.

ZoneId z = ZoneId.of( "Africa/Tunis" ) ;
LocalDate today = LocalDate.now( z ) ;

> shows dates of every 15 days

Define the count of days to jump, and how many times to jump.

int daysToJump = 15 , jumps = 5;  // Jump to 0, 15, 30, 45, 60 days out.

Define the first day from which we will jump.

LocalDate localDate = today;

Loop for the five iterations we want, adding 0, 15, 30, 45, 60. Add daysToJump on each.

for ( int jumpIndex = 0 ; jumpIndex < jumps ; jumpIndex++ ) { … }

for ( int jumpIndex = 0 ; jumpIndex < jumps ; jumpIndex++ )
{
    int daysJumped = ( daysToJump * jumpIndex );
    localDate = localDate.plusDays ( daysJumped );
    System.out.println ( "jumpIndex: " + jumpIndex + " | daysToJump: " + daysToJump + " | localDate = " + localDate );
}

When run.

jumpIndex: 0 | daysJumped: 0 | localDate = 2023-05-25
jumpIndex: 1 | daysJumped: 15 | localDate = 2023-06-09
jumpIndex: 2 | daysJumped: 30 | localDate = 2023-07-09
jumpIndex: 3 | daysJumped: 45 | localDate = 2023-08-23
jumpIndex: 4 | daysJumped: 60 | localDate = 2023-10-22

You said:

>I need o remove Saturdays and Sundays

Yes, we can skip those dates that land on a weekend.

Define the weekend as a set of days of the week. Java comes with seven pre-defined enum objects, one for each day of the week, Monday-Sunday.

Set < DayOfWeek > weekend = EnumSet.of ( DayOfWeek.SATURDAY , DayOfWeek.SUNDAY );

For each jump, add the days to jump, see if that date is on the weekend. If on weekend, ignore that date. If on a weekday, print. Add a test for day-of-week within the loop.

for ( int jumpIndex = 0 ; jumpIndex < jumps ; jumpIndex++ )
{
    int daysJumped = ( daysToJump * jumpIndex );
    localDate = localDate.plusDays ( daysJumped );
    if ( weekend.contains ( localDate.getDayOfWeek ( ) ) ) continue;
    System.out.println ( "jumpIndex: " + jumpIndex + " | daysJumped: " + daysJumped + " | localDate = " + localDate );
}

When run:

jumpIndex: 0 | daysJumped: 0 | localDate = 2023-05-25
jumpIndex: 1 | daysJumped: 15 | localDate = 2023-06-09
jumpIndex: 3 | daysJumped: 45 | localDate = 2023-08-23
