In document creation, divisions of content are frequently required to fulfill specific layout requirements and establish logical structures. The insertion of section breaks and page breaks is the most commonly employed method for dividing content, as it enables flexible control over page and section organization. Moreover, page breaks and section breaks are quite helpful in formatting purposes and the establishment of distinct document styles. This article aims to demonstrate how to use Spire.Doc for Java to insert page breaks and section breaks into Word documents through Java programs.

Install Spire.Doc for Java

First, you're required to add the Spire.Doc.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

<repositories>
    <repository>
        <id>com.e-iceblue</id>
        <name>e-iceblue</name>

Insert Page Breaks into Word Documents

Spire.Doc for Java provides the Paragraph.appendBreak(BreakType.PageBreak) method to insert a page break at the end of a paragraph. The detailed steps are as follows:

• Create an object of Document class.
• Load a Word document using Document.loadFromFile() method.
• Get the first section using Document.getSections().get() method.
• Get the eighth paragraph of the section using Section.getParagraphs().get() method.
• Add a page break to the end of the paragraph using Paragraph.appendBreak(BreakType.PageBreak) method.
• Save the 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.BreakType;
import com.spire.doc.documents.Paragraph;

public class InsertPageBreak {
    public static void main(String[] args) {
        //Create an object of Document class
        Document doc = new Document();

        //Load a Word document
        doc.loadFromFile("Sample.docx");

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

        //Get the eighth paragraph
        Paragraph paragraph = section.getParagraphs().get(7);

        //Add a page break to the end of the paragraph
        paragraph.appendBreak(BreakType.Page_Break);

        //Save the document
        doc.saveToFile("PageBreak.docx", FileFormat.Auto);
    }
}

Insert Section Breaks into Word Documents

Inserting section breaks involves using the Paragraph.insertSectionBreak(SectionBreakType) method. This method allows users to specify the type of section break you want to insert. he following table provides an overview of the section break types, along with their corresponding Enums and descriptions:

The detailed steps for inserting a continuous section break are as follows:

• Create an object of Document class.
• Load a Word document using Document.loadFromFile() method.
• Get the first section using Document.getSections().get() method.
• Get the second paragraph of the section using Section.getParagraphs().get() method.
• Add a continuous section break to the end of the paragraph using Paragraph.insertSectionBreak(SectionBreakType.No_Break) method.
• Save the 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.documents.SectionBreakType;

public class InsertSectionBreak {
    public static void main(String[] args) {
        //Create an object of Document class
        Document doc = new Document();

        //Load a Word document
        doc.loadFromFile("Sample.docx");

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

        //Get the second paragraph
        Paragraph paragraph = section.getParagraphs().get(1);

        //Insert a section break
        paragraph.insertSectionBreak(SectionBreakType.No_Break);

        //Save the document
        doc.saveToFile("SectionBreak.docx", FileFormat.Auto);
    }
}

This article demonstrates how to delete attachments and annotation attachments in a PDF document using Spire.PDF for Java.

Delete Attachments

import com.spire.pdf.attachments.PdfAttachmentCollection;

public class DeleteAttachments {

    public static void main(String[] args) {

        //load a PDF document
        PdfDocument doc = new PdfDocument();
        doc.loadFromFile("C:\\Users\\Administrator\\Desktop\\Attachments.pdf");

        //get the attachments collection, not containing annotation attachments
        PdfAttachmentCollection attachments = doc.getAttachments();
        
        //remove all attachments
        attachments.clear();

        //remove a specific attachment
        //attachments.removeAt(0);

        //save to file
        doc.saveToFile("output/DeleteAttachments.pdf");
        doc.close();
    }
}

Delete Annotation Attachments

import com.spire.pdf.annotations.PdfAnnotation;
import com.spire.pdf.annotations.PdfAnnotationCollection;
import com.spire.pdf.annotations.PdfAttachmentAnnotationWidget;

public class DeleteAnnotationAttachments {

    public static void main(String[] args) {

        //load a PDF document
        PdfDocument doc = new PdfDocument();
        doc.loadFromFile("C:\\Users\\Administrator\\Desktop\\Attachments.pdf");

        //loop through the pages
        for (int i = 0; i < doc.getPages().getCount(); i++) {

            //get the annotations collection
            PdfAnnotationCollection annotationCollection = doc.getPages().get(i).getAnnotationsWidget();

            //loop through the annotations
            for (Object annotation: annotationCollection) {
                
                //determine if an annotation is an instance of PdfAttachmentAnnotationWidget 
                if (annotation instanceof PdfAttachmentAnnotationWidget){
                    
                    //remove the attachment annotation
                    annotationCollection.remove((PdfAnnotation) annotation);
                }
            }
        }

        //save to file
        doc.saveToFile("output/DeleteAnnotationAttachments.pdf");
        doc.close();
    }
}

We have already demonstrated how to set PDF Document Properties in Java. This article we will show you how to set custom properties for PDF files in Java.

import com.spire.pdf.*;

public class PDFCustomProperties {
    public static void main(String[] args) throws Exception {

        String inputPath = "Sample.pdf";
        PdfDocument doc = new PdfDocument(inputPath);
        doc.loadFromFile(inputPath);

        //Set the custom properties
        doc.getDocumentInformation().setCustomerDefined("Number", "123");
        doc.getDocumentInformation().setCustomerDefined("Name", "Daisy");
        doc.getDocumentInformation().setCustomerDefined("Company", "e-iceblue");
       
        //Save the document to file
        doc.saveToFile("Output/result.pdf");
        doc.close();

    }
}
