Calculating a Split Task's Finish Date

Microsoft Project allows users to split tasks when the schedule is interrupted. Aspose.Tasks allows you to calculate the finishing date of a split task.

Split Tasks

The getTaskFinishDateFromDuration method exposed by the Calendar class is used to calculate a split task’s finishing date from the start date, split parts, and duration. The getTaskFinishDateFromDuration method takes a split task and duration as its arguments and returns the tasks finish date.

Calculating a Split Task’s Finish Date with Aspose.Tasks

The following code examples calculate a split task’s finish date.

// For complete examples and data files, please go to https://github.com/aspose-tasks/Aspose.Tasks-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(SplitTaskFinishDate.class);

// Read project
String projectName = dataDir + "SplitTaskProject.mpp";
Project project = new Project(projectName);

// Find a split task
Task splitTask = project.getRootTask().getChildren().getByUid(1);

// Find the project calendar
Calendar calendar = project.get(Prj.CALENDAR);

// Calculate task's finish date with different durations
System.out.println("Start Date: " + splitTask.get(Tsk.START) + "\n+ Duration 8 hours\nFinish Date: "
        + calendar.getTaskFinishDateFromDuration(splitTask, 8d));
System.out.println("Start Date: " + splitTask.get(Tsk.START) + "\n+ Duration 16 hours\nFinish Date: "
        + calendar.getTaskFinishDateFromDuration(splitTask, 16d));
System.out.println("Start Date: " + splitTask.get(Tsk.START) + "\n+ Duration 24 hours\nFinish Date: "
        + calendar.getTaskFinishDateFromDuration(splitTask, 24d));
System.out.println("Start Date: " + splitTask.get(Tsk.START) + "\n+ Duration 28 hours\nFinish Date: "
        + calendar.getTaskFinishDateFromDuration(splitTask, 28d));
System.out.println("Start Date: " + splitTask.get(Tsk.START) + "\n+ Duration 32 hours\nFinish Date: "
        + calendar.getTaskFinishDateFromDuration(splitTask, 32d));
System.out.println("Start Date: " + splitTask.get(Tsk.START) + "\n+ Duration 46 hours\nFinish Date: "
        + calendar.getTaskFinishDateFromDuration(splitTask, 46d));
System.out.println("Start Date: " + splitTask.get(Tsk.START) + "\n+ Duration 61 hours\nFinish Date: "
        + calendar.getTaskFinishDateFromDuration(splitTask, 61d));
System.out.println("Start Date: " + splitTask.get(Tsk.START) + "\n+ Duration 75 hours\nFinish Date: "
        + calendar.getTaskFinishDateFromDuration(splitTask, 75d));
System.out.println("Start Date: " + splitTask.get(Tsk.START) + "\n+ Duration 80 hours\nFinish Date: "
        + calendar.getTaskFinishDateFromDuration(splitTask, 80d));
System.out.println("Start Date: " + splitTask.get(Tsk.START) + "\n+ Duration 120 hours\nFinish Date: "
        + calendar.getTaskFinishDateFromDuration(splitTask, 120d));
System.out.println("Start Date: " + splitTask.get(Tsk.START) + "\n+ Duration 150 hours\nFinish Date: "
        + calendar.getTaskFinishDateFromDuration(splitTask, 150d));
