                //add the last row to the end of the table as a new row
                int rowCount = table.getTableRows().getCount();
                TableRow row = table.getTableRows().get(rowCount - 1);

Modify Hyperlinks in Word in Java

2019-11-12 05:56:30 Written by Koohji

This article demonstrates how to modify hyperlinks in Word including modifying hyperlink address and display text using Spire.Doc for Java.

Below is the sample Word document we used for demonstration:

Modify Hyperlinks in Word in Java

import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.Field;

import java.util.ArrayList;
import java.util.List;

public class ModifyHyperlink {
    public static void main(String[] args) {
        //Load Word document
        Document doc = new Document();
        doc.loadFromFile("Hyperlink.docx");

        List hyperlinks = new ArrayList();

        //Loop through the section in the document
        for (Section section : (Iterable<Section>) doc.getSections()
                ) {
            //Loop through the section in the document
            for (Paragraph para : (Iterable<Paragraph>) section.getParagraphs()
                    ) {
                for (DocumentObject obj:(Iterable<DocumentObject>) para.getChildObjects()
                     ) {
                    if (obj.getDocumentObjectType().equals(DocumentObjectType.Field)) {
                        Field field = (Field) obj;
                        if (field.getType().equals(FieldType.Field_Hyperlink)) {
                            hyperlinks.add(field);
                        }
                    }
                }
            }
        }

        hyperlinks.get(0).setCode("HYPERLINK \"http://www.google.com\"");
        hyperlinks.get(0).setFieldText("www.google.com");

        doc.saveToFile("EditHyperlink.docx", FileFormat.Docx_2013);
    }
}

Output:

We have already demonstrated how to use Spire.Doc to insert footnote to word document in Java applications. This article will show how to remove footnote from word document in Java.

Firstly, view the sample document with footnotes:

Remove footnote from Word document in Java

import com.spire.doc.*;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.fields.*;

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

        //Load the Sample Word document.
        Document document = new Document();
        document.loadFromFile("Sample.docx");

        Section section = document.getSections().get(0);

        //Traverse paragraphs in the section and find the footnote
        for (int j = 0; j < section.getParagraphs().getCount(); j++) {
            Paragraph para = section.getParagraphs().get(j);
            int index = -1;
            for (int i = 0, cnt = para.getChildObjects().getCount(); i < cnt; i++) {
                ParagraphBase pBase = (ParagraphBase) para.getChildObjects().get(i);
                if (pBase instanceof Footnote) {
                    index = i;
                    break;
                }
            }

            if (index > -1)
                //remove the footnote
                para.getChildObjects().removeAt(index);
        }
        document.saveToFile("Removefootnote.docx", FileFormat.Docx);
    }
}
