[Java] Change the Font Color of Paragraph Text in Word

Generally speaking, the font color in Word documents is black by default. However, in order to make some special or important contents – for example, notices in instruction document – more obvious so that readers can easily pay more attention on them, we can change the black font to other colors, such as green, red, yellow.

This article will demonstrate how to change the font color of specified paragraph text in a Word document using Java codes with the help of a free third-party library called Free Spire.Doc for Java.

DEVELOPMENT ENVIRONMENT

Before running codes, we need to create a development environment and add a Jar file called Spire.Doc.jar to Intellij IDEA. The jar file can be found in the “lib” folder of the free library, and then follow the steps listed in the screenshot below.

Actually, there is another method to add the Jar file to IDEA. Create a Maven project in IDEA, and then write down the following codes in the pom.xml file. Finally, click the button “Import Changes”.

RUNNING THE CODE

Here is a Word sample document whose font color is black, and now I’ll use Java codes to change the 

font color of second paragraph text to green and third paragraph text to blue.

import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.TextRange;
import java.awt.*;

public class ChangeFontColor {
    public static void main(String[] args) {
        //Create a Document instance
        Document doc = new Document();
        //Load the Word document
        doc.loadFromFile("C:\\Users\\Test1\\Desktop\\Sample.docx");

        //Get the first section and second paragraph
        Section section = doc.getSections().get(0);
        Paragraph p1 = section.getParagraphs().get(1);

        //Iterate through the childObjects of the second paragraph
        for (int i = 0; i < p1.getChildObjects().getCount(); i ++)
        {
            //Change font color of the text in the second paragraph
            if ( p1.getChildObjects().get(i) instanceof TextRange)
            {
                TextRange tr = (TextRange) p1.getChildObjects().get(i);
                tr.getCharacterFormat().setTextColor(Color.green);
            }
        }

        //Get the third paragraph
        Paragraph p2 = section.getParagraphs().get(2);

        //Iterate through the childObjects of the third paragraph
        for (int j = 0; j < p2.getChildObjects().getCount(); j ++)
        {
            //Change font color of the text in the third paragraph
            if ( p2.getChildObjects().get(j) instanceof TextRange)
            {
                TextRange tr = (TextRange) p2.getChildObjects().get(j);
                tr.getCharacterFormat().setTextColor(Color.blue);
            }
        }

        //Save the resulting document
        doc.saveToFile("output/ChangeFontColor.docx", FileFormat.Docx_2013);
    }
}
