]Tasks can be identified by a number of general properties, such as name, ID, start and finish date. Aspose.Tasks can be used to get and set task properties when working with projects.
General Properties
The Task exposes several general properties:
- Name, used to set and get a task’s name (string).
- Id, used to set and get a task’s ID (integer).
- Uid, used to set and get a task’s unique ID (integer).
- Start, used to set and get a task’s start date (DateTime).
- Finish, used to set and get a task’s end date (DateTime).
To view a task’s general properties in Microsoft Project:
- Open a project.
- On the View menu, select More Views and then Task Entry to open the task entry form.
- From the Insert menu, select Column and add the ID and Unique ID as shown in the screenshot below.

Setting General Properties
To set the properties shown in the screenshot above, use the code below.
1// For complete examples and data files, please go to https://github.com/aspose-tasks/Aspose.Tasks-for-Java
2// The path to the documents directory.
3String dataDir = Utils.getDataDir(ReadWriteGeneralProperties.class);
4
5Project project = new Project();
6Task task = project.getRootTask().getChildren().add("Task1");
7// Set task start date
8java.util.Calendar cal = java.util.Calendar.getInstance();
9cal.set(2013, 7, 17, 8, 0, 0);
10task.set(Tsk.START, cal.getTime());
11// Set task name
12task.set(Tsk.NAME, "new name");Getting General Properties
Get a task’s properties by traversing the children of the project’s RootTask property.

2// The path to the documents directory.
3String dataDir = Utils.getDataDir(ReadWriteGeneralProperties.class);
4
5Project prj = new Project(dataDir + "project.mpp");
6// Create a ChildTasksCollector instance
7ChildTasksCollector collector = new ChildTasksCollector();
8
9// Collect all the tasks from RootTask using TaskUtils
10TaskUtils.apply(prj.getRootTask(), collector, 0);
11
12// Parse through all the collected tasks
13for (Task tsk : collector.getTasks()) {
14 System.out.println("Task Id:" + tsk.get(Tsk.ID));
15 System.out.println("Task Uid: " + tsk.get(Tsk.UID));
16 System.out.println("Task Name: " + tsk.get(Tsk.NAME));
17 System.out.println("Task Start: " + tsk.get(Tsk.START));
18 System.out.println("Task Finish: " + tsk.get(Tsk.FINISH));
