// Custom properties are available through the typed collection:
38-
for (CustomProjectProperty property : project.getCustomProps()) {
39-
System.out.println(property.getType());
40-
System.out.println(property.getName());
41-
System.out.println(property.getValue());
42-
}
43-
44-
// Built-in properties are available directly:
45-
System.out.println(project.getBuiltInProps().getAuthor());
46-
System.out.println(project.getBuiltInProps().getTitle());
47-
48-
// or as an item of built-in property collection:
49-
for (BuiltInProjectProperty property : project.getBuiltInProps()) {
50-
System.out.println(property.getName());
51-
System.out.println(property.getValue());
52-
}
53-
// ExEnd:ReadMetaProperties
54-
}
26+
## Step 1. Set Data Directory
27+
First, ensure you set the data directory where your project file resides.
28+
```java
29+
String dataDir = "Your Data Directory";
30+
```
31+
## Step 2. Initialize Project Object
32+
Create an instance of the `Project` class, passing the path to your project file.
33+
```java
34+
Project project = new Project(dataDir + "project.mpp");
35+
```
36+
## Step 3. Read Custom Properties
37+
Iterate through custom properties using a typed collection and print their details.
38+
```java
39+
for (CustomProjectProperty property : project.getCustomProps()) {
40+
System.out.println("Type: " + property.getType());
41+
System.out.println("Name: " + property.getName());
42+
System.out.println("Value: " + property.getValue());
5543
}
5644
```
45+
## Step 4. Access Built-in Properties
46+
Access built-in properties directly and print their values.
47+
```java
48+
System.out.println("Author: " + project.getBuiltInProps().getAuthor());
49+
System.out.println("Title: " + project.getBuiltInProps().getTitle());
50+
```
51+
## Step 5. Iterate Through Built-in Properties
52+
Alternatively, iterate through built-in properties and print their details.
53+
```java
54+
for (BuiltInProjectProperty property : project.getBuiltInProps()) {
55+
System.out.println("Name: " + property.getName());
56+
System.out.println("Value: " + property.getValue());
57+
}
58+
```
59+
This step-by-step guide equips you with the proficiency to unravel meta-properties within your Aspose.Tasks projects effortlessly.
