Prerequisites
Before you begin, make sure you have the Aspose.Words for Java library set up in your project. You can download it from here.
Adding Text
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Insert a simple text paragraph
builder.write("This is a simple text paragraph.");
// Save the document
doc.save("path/to/your/document.docx");
Adding Tables
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Start a table
Table table = builder.startTable();
// Insert cells and content
builder.insertCell();
builder.write("Cell 1");
builder.insertCell();
builder.write("Cell 2");
// End the table
builder.endTable();
// Save the document
doc.save("path/to/your/document.docx");
Adding Horizontal Rule
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Insert a horizontal rule
builder.insertHorizontalRule();
// Save the document
doc.save("path/to/your/document.docx");
Adding Form Fields
Text Input Form Field
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Insert a text input form field
builder.insertTextInput("TextInput", TextFormFieldType.REGULAR, "", "Default text", 0);
// Save the document
doc.save("path/to/your/document.docx");
Check Box Form Field
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Insert a check box form field
builder.insertCheckBox("CheckBox", true, true, 0);
// Save the document
doc.save("path/to/your/document.docx");
Combo Box Form Field
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Define items for the combo box
String[] items = { "Option 1", "Option 2", "Option 3" };
// Insert a combo box form field
builder.insertComboBox("DropDown", items, 0);
// Save the document
doc.save("path/to/your/document.docx");
Adding HTML
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Insert HTML content
builder.insertHtml("<p>This is an HTML paragraph.</p>");
// Save the document
doc.save("path/to/your/document.docx");
Adding Hyperlinks
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Insert a hyperlink
builder.write("Visit ");
builder.getFont().setColor(Color.BLUE);
builder.getFont().setUnderline(Underline.SINGLE);
builder.insertHyperlink("Aspose Website", "http://www.aspose.com", false);
builder.getFont().clearFormatting();
builder.write(" for more information.");
// Save the document
doc.save("path/to/your/document.docx");
Adding a Table of Contents
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Insert a table of contents
builder.insertTableOfContents("\\o \"1-3\" \\h \\z \\u");
// Add document content
// ...
// Update the table of contents
doc.updateFields();
// Save the document
doc.save("path/to/your/document.docx");
Adding Images
Inline Image
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Insert an inline image
builder.insertImage("path/to/your/image.png");
// Save the document
doc.save("path/to/your/document.docx");
Floating Image
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Insert a floating image
builder.insertImage("path/to/your/image.png", RelativeHorizontalPosition.MARGIN, 100.0, RelativeVerticalPosition.MARGIN, 100.0, 200.0, 100.0, WrapType.SQUARE);
// Save the document
doc.save("path/to/your/document.docx");
Adding Paragraphs
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Set paragraph formatting
Font font = builder.getFont();
font.setSize(16.0);
font.setBold(true);
font.setColor(Color.BLUE);
font.setName("Arial");
font.setUnderline(Underline.DASH);
ParagraphFormat paragraphFormat = builder.getParagraphFormat();
paragraphFormat.setFirstLineIndent(8.0);
paragraphFormat.setAlignment(ParagraphAlignment.JUSTIFY);
paragraphFormat.setKeepTogether(true);
// Insert a paragraph
builder.writeln("This is a formatted paragraph.");
// Save the document
doc.save("path/to/your/document.docx");
Step 10: Moving the Cursor
You can control the cursor position within the document using various methods like moveToParagraph, moveToCell, and more. Here’s an example:
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Move the cursor to a specific paragraph
builder.moveToParagraph(2, 0);
// Add content at the new cursor position
builder.writeln("This is the 3rd paragraph.");
