Add Titles, Headings, and Paragraphs to a Word Document in Java
When creating structured Word documents with Spire.Doc for .NET, its core functionality revolves around the Document and Section classes. Use the addParagraph() method to add new paragraphs and the appendText() method to insert text content. To ensure consistent formatting, you can apply built-in styles (such as Title or Heading 1-4), which achieve professional and standardized typesetting effects. You can also customize styles to precisely control fonts, colors, and sizes, thereby creating personalized document designs.
The steps to add titles, headings, and paragraphs to a Word document in Java are as follows:
- Create a Document object.
- Use Document.addSection() to add sections to the document.
- Use Section.addParagraph() to add paragraphs to a section.
- Apply built-in styles (Title, Heading1, Heading2, Heading3) to specific paragraphs using Paragraph.applyStyle().
- Define a custom paragraph style using ParagraphStyle() and apply it to the specified paragraph.
- Save the document as a DOCX file.
- Java
import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.*;
import java.awt.Color;
public class CreateSimpleDocument {
public static void main(String[] args) {
// Create a Document object
Document document = new Document();
// Add a section
Section section = document.addSection();
// Set page margins
section.getPageSetup().getMargins().setAll(60f);
// Add a title paragraph
Paragraph title_para = section.addParagraph();
TextRange textRange = title_para.appendText("This Is Title");
title_para.applyStyle(BuiltinStyle.Title);
textRange.getCharacterFormat().setFontName("Times New Roman");
// Add a couple of heading paragraphs
Paragraph heading_one = section.addParagraph();
textRange = heading_one.appendText("Heading 1");
heading_one.applyStyle(BuiltinStyle.Heading_1);
textRange.getCharacterFormat().setFontName("Times New Roman");
Paragraph heading_two = section.addParagraph();
textRange = heading_two.appendText("Heading 2");
heading_two.applyStyle(BuiltinStyle.Heading_2);
textRange.getCharacterFormat().setFontName("Times New Roman");
Paragraph heading_three = section.addParagraph();
textRange = heading_three.appendText("Heading 3");
heading_three.applyStyle(BuiltinStyle.Heading_3);
textRange.getCharacterFormat().setFontName("Times New Roman");
Paragraph heading_four = section.addParagraph();
textRange = heading_four.appendText("Heading 4");
heading_four.applyStyle(BuiltinStyle.Heading_4);
textRange.getCharacterFormat().setFontName("Times New Roman");
// Add a normal paragraph
Paragraph normal_para = section.addParagraph();
normal_para.appendText("This is a sample paragraph.");
// Create a paragraph style
ParagraphStyle style = new ParagraphStyle(document);
style.setName("paraStyle");
style.getCharacterFormat().setFontName("Times New Roman");
style.getCharacterFormat().setFontSize(13f);
style.getCharacterFormat().setTextColor(Color.blue);
document.getStyles().add(style);
// Apply the custom style to the paragraph
normal_para.applyStyle("paraStyle");
// Save the document
document.saveToFile("output/AddText.docx", FileFormat.Docx);
// Dispose resources
document.dispose();
}
}
Add an Image to a Word Document in Java
To insert an image into a Word document, you first need to create a dedicated paragraph element as the image container. By using the appendPicture() method, you can load an image from the file system and embed it directly into the document structure.
The steps to add an image to a Word document in Java are as follows:
- Create a Document object.
- Use Document.addSection() to add a section to the document.
- Add a paragraph to the section using Section.addParagraph().
- Insert the image into the paragraph using Paragraph.appendPicture().
- Save the document as a DOCX file.
- Java
import com.spire.doc.*;
import com.spire.doc.documents.*;
import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
public class AddImage {
public static void main(String[] args) throws IOException {
// Create a Document object
Document document = new Document();
// Add a section
Section section = document.addSection();
// Set page margins
section.getPageSetup().getMargins().setAll(60f);
// Add a paragraph
Paragraph image_para = section.addParagraph();
// Load an image file
BufferedImage image = ImageIO.read(new File("C:\\Users\\Administrator\\Desktop\\logo.png"));
// Append it to the paragraph
image_para.appendPicture(image);
// Save the document
document.saveToFile("output/AddImage.docx", FileFormat.Docx);
// Dispose resources
document.dispose();
}
}
Add a Table to a Word Document in Java
The table creation process begins with the addTable() method, which is used to establish the basic table structure. Using the resetCells() method, you can specify the desired number of rows and columns. Once initialized, filling each cell with content requires first adding a paragraph element via the addParagraph() method, followed by inserting text using the appendText() method.
The steps to add a table to a Word document in Java are as follows:
- Create a Document object.
- Use Document.addSection() to add a section to the document.
- Create a two-dimensional array to store table data (including headers and values).
- Generate the table using Section.addTable().
- Call the Table.resetCells() method to define the number of rows and columns based on the data.
- Iterate through the data array and use the TableCell.addParagraph() and Paragraph.appendText() methods to add text to each cell.
- Save the document as a DOCX file.
- Java
import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.*;
public class AddTable {
public static void main(String[] args) {
// Create a Document object
Document document = new Document();
// Add a section
Section section = document.addSection();
// Set page margins
section.getPageSetup().getMargins().setAll(60f);
// Define table data as a 2D array
String[][] data = {
{"Product", "Unit Price", "Quantity", "Sub Total"},
{"A", "$29", "120", "$3,480"},
{"B", "$35", "110", "$3,850"},
{"C", "$68", "140", "$9,520"}
};
// Add a table
Table table = section.addTable(true);
// Set row number and column number
table.resetCells(data.length, data[0].length);
// Write data to cells
for (int r = 0; r < data.length; r++) {
TableRow row = table.getRows().get(r);
row.setHeight(20);
row.setHeightType(TableRowHeightType.Exactly);
for (int c = 0; c < data[r].length; c++) {
TableCell cell = row.getCells().get(c);
cell.getCellFormat().setVerticalAlignment(VerticalAlignment.Middle);
TextRange textRange = cell.addParagraph().appendText(data[r][c]);
textRange.getCharacterFormat().setFontName("Times New Roman");
textRange.getCharacterFormat().setFontSize(14);
}
}
// Automatically adjusts the column widths of a table to fit its contents
table.autoFit(AutoFitBehaviorType.Auto_Fit_To_Contents);
// Save the document to file
document.saveToFile("output/AddTable.docx", FileFormat.Docx);
// Dispose resources
document.dispose();
}
}
Add a List to a Word Document in Java
The ListStyle class provides the foundation for implementing bulleted lists and numbered lists in documents. By configuring this class, you can establish a unified visual format for all list items. Once the list style is defined, simply apply it to target paragraphs using the applyStyle() method.
The steps to add a list to a Word document in Java are as follows:
- Create a Document object.
- Use Document.addSection() to add a section to the document.
- Define the list style using ListStyle().
- Add paragraphs to the section using Section.addParagraph().
- Apply the defined list style to paragraphs using Paragraph.getListFormat().applyStyle().
- Save the document as a DOCX file.
- Java
import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.*;
public class AddList {
public static void main(String[] args) {
// Create a Document object
Document document = new Document();
// Add a section
Section section = document.addSection();
// Set page margins
section.getPageSetup().getMargins().setAll(60f);
// Create a bulleted list style
ListStyle listStyle = new ListStyle(document, ListType.Bulleted);
listStyle.setName("bulletedList");
listStyle.getLevels().get(0).setBulletCharacter("\u00B7");
listStyle.getLevels().get(0).getCharacterFormat().setFontName("Symbol");
listStyle.getLevels().get(0).setTextPosition(20);
document.getListStyles().add(listStyle);
// Add a paragraph
Paragraph paragraph = section.addParagraph();
TextRange textRange = paragraph.appendText("Fruits:");
paragraph.getFormat().setAfterSpacing(5f);
textRange.getCharacterFormat().setFontName("Times New Roman");
textRange.getCharacterFormat().setFontSize(14);
// Add another four paragraphs as bulleted list items
String[] fruits = {"Apple", "Banana", "Watermelon", "Mango"};
for (String fruit : fruits) {
paragraph = section.addParagraph();
textRange = paragraph.appendText(fruit);
paragraph.getListFormat().applyStyle(listStyle.getName());
paragraph.getListFormat().setListLevelNumber(0);
textRange.getCharacterFormat().setFontName("Times New Roman");
textRange.getCharacterFormat().setFontSize(14);
}
// Save the document to file
document.saveToFile("output/AddList.docx", FileFormat.Docx);
// Dispose resources
document.dispose();
}
}
