Java: Set Paragraph Indents in Word

In Microsoft Word, we can set the paragraph indents as left, right, first line or hanging. In this article, we will demonstrate how to achieve this functionality using Spire.Doc for Java.

Set Paragraph Indents in Word

Spire.Doc for Java provides a ParagraphFormat class to work with paragraph formatting. You can use Paragraph.getFormat() method to get the ParagraphFormat object, and then use the following methods to set the corresponding paragraph indents with the object:

The following are the steps to set paragraph indents:

• Create a Document instance.
• Load a Word document using Document.loadFromFile() method.
• Get the desired section by its index using Document.getSections.get() method.
• Get the desired paragraph by index using Section.getParagraphs.get() method.
• Get the ParagraphFormat object using Paragraph.getFormat() method.
• Call the methods listed in above table to set paragraph indents with the object.
• Save the result document using Document.saveToFile() method.

import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.formatting.ParagraphFormat;

public class IndentParagraph {
    public static void main(String[] args) {
        //Create a Document instance
        Document document= new Document();
        //Load a Word document
        document.loadFromFile("Input.docx");

        //Get the first section
        Section section = document.getSections().get(0);

        //Get the second paragraph and set left indent
        Paragraph para = section.getParagraphs().get(1);
        ParagraphFormat format = para.getFormat();
        format.setLeftIndent(30);

        //Get the third paragraph and set right indent
        para = section.getParagraphs().get(2);
        format = para.getFormat();
        format.setRightIndent(30);

        //Get the fourth paragraph and set first line indent
        para = section.getParagraphs().get(3);
        format = para.getFormat();
        format.setFirstLineIndent(30);

        //Get the fifth paragraph and set hanging indent
        para = section.getParagraphs().get(4);
        format = para.getFormat();
        format.setFirstLineIndent(-30);

        //Save the result document
        document.saveToFile("SetParagraphIndents.docx", FileFormat.Docx_2013);
    }
}

The following is the output Word document after setting paragraph indents:
