Hello World Example

A “Hello, World” example is traditionally used to introduce features of a programming language or software with a simple use case. Here is the example for LINQ Reporting Engine.

Assume, that you have the Sender class defined in your application as follows:

// For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-Java
public class Sender {
    private String Name;

    public final String getName() {
        return Name;
    }

    public final void setName(String value) {
        Name = value;
    }

    private String Message;

    public final String getMessage() {
        return Message;
    }

    public final void setMessage(String value) {
        Message = value;
    }
}

To produce a report containing a message of a concrete sender on its behalf, you can use a template document with the following content.

<<[s.getName()]>> says: "<<[s.getMessage()]>>."

To build a report from the template, you can use the following source code.

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

String fileName = "HelloWorld.doc";
// Load the template document.
Document doc = new Document(dataDir + fileName);

// Create an instance of sender class to set it's properties.
Sender sender = new Sender();
sender.setName("LINQ Reporting Engine");
sender.setMessage("Hello World");

// Create a Reporting Engine.
ReportingEngine engine = new ReportingEngine();

// Execute the build report.
engine.buildReport(doc, sender, "sender");

dataDir = dataDir + Utils.GetOutputFilePath(fileName);

// Save the finished document to disk.
doc.save(dataDir);

After the source code is ran, the template document is populated with the data about the sender, and the document becomes a ready report with the following content.

LINQ Reporting Engine says: "Hello, World."

After the report document is built, you can save it or perform any other tasks on it using Aspose.Words API in your code.
