A bookmark in Word works like a bookmark we might place in a book. We can use a bookmark to quickly jump to a specific location within a Word document. In this article, we’re going to introduce how to add bookmarks, replace the content of bookmarks and remove bookmarks in a Word document programmatically in Java using Free Spire.Doc for Java API.

Before Start

Download Free Spire.Doc for Java from this link and import the Spire.Doc.jar file into your Java project.

Using the code

    Introduction

    Form Fields allow users to interactive with PDF file by filling in information or making selections, which can then be submitted for processing. The types of PDF form fields including text input field, check box, radio button, combo box, list box, and button. This tip will show how to create and fill such form fields in PDF programmatically in Java using Free Spire.PDF for Java API.

    Adding Dependencies

    For maven projects, we could easily add dependencies to the Free Spire.PDF for Java API by adding the following code in pom.xml:

    (The latest version of Free Spire.PDF for Java in maven repository can be found here.)

    For common Java projects, download the latest version of Free Spire.PDF for Java, (download link), then add Spire.Pdf.jar from the lib folder into your project.

    Using the code

    The following table shows the form fields and the corresponding class in Free Spire.PDF for Java API:

    Form FieldClass
    Text input fieldPdfTextBoxField
    Check boxPdfCheckBoxField
    List boxPdfListBoxField
    Combo boxPdfComboBoxField
    Radio buttonPdfRadioButtonListField
    ButtonPdfButtonField


  • Creating form fields


  • To create a form field, we first need to create an instance of the corresponding class, and then add it to the form fields collection using the add method of class PdfFormFieldCollection.


  • Filling form fields


  • To fill form fields, we need to determine the types of the fields. Below example shows how to determine the types of form fields and fill the form fields with value.


    Additional information

    There are many more manipulations (such as change appearance, clone, delete, move to another location and add JavaScript) we could do with PDF form fields except that introduced above. If interested, you can give it a try by yourself.
