| 10 | +## Introduction |
| 11 | +Aspose.Tasks for Java is a powerful library that allows developers to manipulate Microsoft Project files with ease. In this tutorial, we'll walk through the process of reading group definition data from a project file step by step using Aspose.Tasks for Java. |
| 12 | +## Prerequisites |
| 13 | +Before we begin, ensure you have the following prerequisites: |
| 14 | +1. Java Development Kit (JDK): Make sure you have JDK installed on your system. |
| 15 | +2. Aspose.Tasks for Java Library: Download and install the Aspose.Tasks for Java library from [here](https://releases.aspose.com/tasks/java/). |
| 16 | +3. Integrated Development Environment (IDE): Choose your preferred IDE such as IntelliJ IDEA or Eclipse. |
| 17 | + |
| 18 | +## Import Packages |
| 19 | +First, let's import the necessary packages to begin working with Aspose.Tasks for Java. |
| 20 | +```java |
23 | 21 | import com.aspose.tasks.*; |
24 | | - |
25 | | - |
26 | | -public class ReadGroupDefinitionData { |
27 | | - public static void main(String[] args) { |
28 | | - // The path to the documents directory. |
29 | | - String dataDir = "Your Data Directory"; |
30 | | - |
31 | | - Project project = new Project(dataDir + "project.mpp"); // attached test project |
32 | | - |
33 | | - System.out.println("Task Groups Count: " + project.getTaskGroups().size()); |
34 | | - |
35 | | - Group taskGroup = project.getTaskGroups().toList().get(1); |
36 | | - System.out.println("Percent Complete:" + taskGroup.getName()); |
37 | | - System.out.println("Group Criteria count: " + taskGroup.getGroupCriteria().size()); |
38 | | - |
39 | | - System.out.println("\n************* Retrieving Task Group's Criterion information *************"); |
40 | | - GroupCriterion criterion = taskGroup.getGroupCriteria().toList().get(0); |
41 | | - System.out.println("Criterion Field: " + criterion.getField()); |
42 | | - System.out.println("Criterion GroupOn: " + criterion.getGroupOn()); |
43 | | - System.out.println("Criterion Cell Color: " + criterion.getCellColor()); |
44 | | - System.out.println("Criterion Pattern: " + criterion.getPattern()); |
45 | | - |
46 | | - if (taskGroup == criterion.getParentGroup()) |
47 | | - System.out.println("Parent Group is equval to task Group."); |
48 | | - |
49 | | - System.out.println("\n*********** Retreivnig Criterion's Font Information ***********"); |
50 | | - System.out.println("Font Family Name: " + criterion.getFont().getFontFamily()); |
51 | | - System.out.println("Font Size: " + criterion.getFont().getSize()); |
52 | | - System.out.println("Font Style: " + criterion.getFont().getStyle()); |
53 | | - System.out.println("Ascending/Dscending: " + criterion.getAscending()); |
54 | | - } |

61 | 22 | ``` |
| 23 | +## Step 1: Set Up Your Data Directory |
| 24 | +```java |
| 25 | +String dataDir = "Your Data Directory"; |
| 26 | +``` |
| 27 | +Replace `"Your Data Directory"` with the path to the directory containing your project file. |
| 28 | +## Step 2: Load the Project File |
| 29 | +```java |
| 30 | +Project project = new Project(dataDir + "project.mpp"); |
| 31 | +``` |
| 32 | +Load your project file using the `Project` class constructor, passing the path to your project file. |
| 33 | +## Step 3: Retrieve Task Groups Count |
| 34 | +```java |
| 35 | +System.out.println("Task Groups Count: " + project.getTaskGroups().size()); |
| 36 | +``` |
| 37 | +Retrieve the count of task groups in the project using the `getTaskGroups()` method. |
| 38 | +## Step 4: Retrieve Task Group Information |
| 39 | +```java |
| 40 | +Group taskGroup = project.getTaskGroups().toList().get(1); |
| 41 | +System.out.println("Percent Complete:" + taskGroup.getName()); |
| 42 | +System.out.println("Group Criteria count: " + taskGroup.getGroupCriteria().size()); |
| 43 | +``` |
| 44 | +Retrieve information about a specific task group, such as its name and the count of group criteria. |
| 45 | +## Step 5: Retrieve Group Criterion Information |
| 46 | +```java |
| 47 | +GroupCriterion criterion = taskGroup.getGroupCriteria().toList().get(0); |
| 48 | +System.out.println("Criterion Field: " + criterion.getField()); |
| 49 | +System.out.println("Criterion GroupOn: " + criterion.getGroupOn()); |
| 50 | +System.out.println("Criterion Cell Color: " + criterion.getCellColor()); |
| 51 | +System.out.println("Criterion Pattern: " + criterion.getPattern()); |
| 52 | +``` |
| 53 | +Retrieve information about the group criteria, such as the field, group on, cell color, and pattern. |
| 54 | +## Step 6: Check Parent Group |
| 55 | +```java |
| 56 | +if (taskGroup == criterion.getParentGroup()) |
| 57 | + System.out.println("Parent Group is equval to task Group."); |
| 58 | +``` |
| 59 | +Check if the parent group is equal to the task group. |
| 60 | +## Step 7: Retrieve Criterion's Font Information |
| 61 | +```java |
| 62 | +System.out.println("Font Family Name: " + criterion.getFont().getFontFamily()); |
| 63 | +System.out.println("Font Size: " + criterion.getFont().getSize()); |
| 64 | +System.out.println("Font Style: " + criterion.getFont().getStyle()); |
| 65 | +System.out.println("Ascending/Descending: " + criterion.getAscending()); |
| 66 | +``` |
| 67 | +Retrieve font information for the criterion, such as font family, size, style, and sorting order. |
| 68 | + |
