11 | | -## Complete Source Code |
| 10 | +## Introduction |
| 11 | +In this tutorial, we will walk through the process of defining weekdays in an MS Project Calendar using Aspose.Tasks for Java. Aspose.Tasks is a powerful Java library that enables developers to manipulate Microsoft Project files programmatically. |
| 12 | +## Prerequisites |
| 13 | +Before we begin, ensure you have the following prerequisites in place: |
| 14 | +1. Java Development Kit (JDK): Make sure you have JDK installed on your system. You can download it from the [official Oracle website](https://www.oracle.com/java/technologies/javase-jdk11-downloads.html) if you haven't already. |
| 15 | +2. Aspose.Tasks for Java Library: Download and install the Aspose.Tasks for Java library from the [download page](https://releases.aspose.com/tasks/java/). Follow the installation instructions provided in the documentation. |
| 16 | + |
| 17 | +## Import Packages |
| 18 | +To start, import the necessary packages required for working with Aspose.Tasks in your Java project: |

| 23 | +## Step 1: Create a Project Instance |
| 24 | +Instantiate a Project object, which represents the MS Project file you will be working with: |
| 25 | +```java |
| 26 | +// The path to the documents directory. |
| 27 | +String dataDir = "Your Data Directory"; |
| 28 | +Project prj = new Project(); |
| 29 | +``` |
| 30 | +## Step 2: Define Calendar |
| 31 | +Create a new calendar instance and add it to the project: |
| 32 | +```java |
| 33 | +Calendar cal = prj.getCalendars().add("Calendar1"); |
| 34 | +``` |
| 35 | +## Step 3: Add Working Days |
| 36 | +Define the working days by adding Monday through Thursday with default timings: |
| 37 | +```java |
| 38 | +cal.getWeekDays().add(WeekDay.createDefaultWorkingDay(DayType.Monday)); |
| 39 | +cal.getWeekDays().add(WeekDay.createDefaultWorkingDay(DayType.Tuesday)); |
| 40 | +cal.getWeekDays().add(WeekDay.createDefaultWorkingDay(DayType.Wednesday)); |
| 41 | +cal.getWeekDays().add(WeekDay.createDefaultWorkingDay(DayType.Thursday)); |
| 42 | +``` |
| 43 | +## Step 4: Set Custom Working Day |
| 44 | +Define Saturday and Sunday as working days: |
| 45 | +```java |
| 46 | +cal.getWeekDays().add(new WeekDay(DayType.Saturday)); |
| 47 | +cal.getWeekDays().add(new WeekDay(DayType.Sunday)); |
| 48 | +``` |
| 49 | +## Step 5: Set Short Working Day |
| 50 | +Set Friday as a short working day with custom working times: |
| 51 | +```java |
| 52 | +WeekDay myWeekDay = new WeekDay(DayType.Friday); |
| 53 | +WorkingTime wt1 = new WorkingTime( |
| 54 | + new GregorianCalendar(1, java.util.Calendar.JANUARY, 1, 9, 0, 0).getTime(), |
| 55 | + new GregorianCalendar(1, java.util.Calendar.JANUARY, 1, 12, 0, 0).getTime() |
| 56 | +); |
| 57 | +WorkingTime wt2 = new WorkingTime( |
| 58 | + new GregorianCalendar(1, java.util.Calendar.JANUARY, 1, 13, 0, 0).getTime(), |
| 59 | + new GregorianCalendar(1, java.util.Calendar.JANUARY, 1, 16, 0, 0).getTime() |
| 60 | +); |
| 61 | +myWeekDay.getWorkingTimes().add(wt1); |
| 62 | +myWeekDay.getWorkingTimes().add(wt2); |
| 63 | +myWeekDay.setDayWorking(true); |
| 64 | +cal.getWeekDays().add(myWeekDay); |
| 65 | +``` |
| 66 | +## Step 6: Save the Project |
| 67 | +Save the modified project to an XML file: |
| 68 | +```java |
| 69 | +prj.save(dataDir + "project.xml", SaveFileFormat.Xml); |
| 70 | +``` |
| 71 | + |
