How to Hide a Specific Paragraph in a Word Document in Java

 Sometimes when editing text, we need to keep some important information private and don't want someone to see a paragraph, or really don't want it to be there, but also don't want to delete it. For this reason, they can be hidden to ensure confidentiality. So in today’s post, I will give you the instructions on how to hide a specific paragraph in a Word document through code in a Java program. Follow these steps and you can do it without any problems.

Programming Environment

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.

Method 1:

Introduced manually. Download Free Spire.Doc for Java locally, unzip it, and find the Spire.Doc.jar file in the lib folder. Open the following interface in IDEA, and import the jar file in the local path into the Java program:

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>
            <url>https://repo.e-iceblue.com/repository/maven-public/</url>
        </repository>
    </repositories>
<dependencies>
    <dependency>
        <groupId>e-iceblue</groupId>
        <artifactId>spire.doc.free</artifactId>
        <version>5.2.0</version>
    </dependency>
</dependencies>

Specific Steps:

• Create a Document instance.
• Load a sample Word document using Document.loadFromFile() method.
• Get a specific section of the Word document using Document.getSections().get() method.
• Get a specific paragraph of the section using Section.getParagraphs().get() method.
• Loop through the child objects of the paragraph, and convert each child object as a text range if it is plain text. Then hide the text range using TextRange.getCharacterFormat().setHidden(boolean value) method.
• Save the document to another file using Document.saveToFile() method.

Java

import com.spire.doc.*; 
import com.spire.doc.documents.*; 
import com.spire.doc.fields.*; 
 
public class HideParagraph { 
public static void main(String[] args) { 
//Create a Document instance 
Document document = new Document(); 
 
//Load a sample Word document 
document.loadFromFile("Sample.docx"); 
 
//Get a specific section of Word 
Section sec = document.getSections().get(0); 
 
//Get a specific paragraph of the section 
Paragraph para = sec.getParagraphs().get(1); 
 
//Loop through the child objects 
for (Object docObj : para.getChildObjects()) { 
DocumentObject obj = (DocumentObject)docObj; 
 
//Determine if a child object is an instance of TextRange 
if ((obj instanceof TextRange)) { 
TextRange range = ((TextRange)(obj)); 
 
//Hide the text range 
range.getCharacterFormat().setHidden(true); 
} 
} 
 
//Save the document to another file 
document.saveToFile("hideParagraph.docx", FileFormat.Docx_2013); 
} 
}
