Written by support iceblueThe following code snippets demonstrate how to indent paragraphs for Word document in Java applications. With the help of Spire.Doc for Java, developers can set the paragraph indentation easily. There are four kinds of paragraph indentation style for word document: Left Indentation, Right Indentation, First Line Indentation and Hanging Indentation.
import com.spire.doc.*;
import com.spire.doc.documents.*;
public class WordparaIndent {
public static void main(String[] args) {
//load the sample document
Document document= new Document();
document.loadFromFile("Sample.docx");
Section section = document.getSections().get(0);
//get the second paragraph and set the left indent
Paragraph para1 = section.getParagraphs().get(1);
para1.getFormat().setLeftIndent(30);
//get the third paragraph and set the right indent
Paragraph para2 = section.getParagraphs().get(2);
para2.getFormat().setRightIndent(30);
//get the fourth paragraph and set the first line indent
Paragraph para3 = section.getParagraphs().get(3);
para3.getFormat().setFirstLineIndent(40);
//get the fifth paragraph and set the hanging indent
Paragraph para4 = section.getParagraphs().get(4);
para4.getFormat().setFirstLineIndent(-40);
//save the document to file
document.saveToFile("out/WordIndent.docx", FileFormat.Docx_2013);
}
}
