This article will show you how to use Spire.PDF for Java to draw superscript and subscript text to PDF file in Java applications.
Draw Superscript Text
import com.spire.pdf.*;
import com.spire.pdf.graphics.*;
import java.awt.*;
import java.awt.geom.*;
public class PdfSuperscriptText {
public static void main(String[] args) {
//Create a new PdfDocument instance
PdfDocument doc = new PdfDocument();
//Add a page to pdf
PdfPageBase page = doc.getPages().add();
//Set the font
PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", Font.PLAIN,14),true);
PdfSolidBrush brush = new PdfSolidBrush(new PdfRGBColor(Color.black));
//Set initial (x, y) coordinate
float x = 120f;
float y = 100f;
//Draw text string
String text = "Sample Text";
page.getCanvas().drawString(text, font, brush, new Point2D.Float(x, y));
//Measure the string
Dimension2D size = font.measureString(text);
x += size.getWidth();
//Draw the text string and set the format as Superscript
PdfStringFormat format = new PdfStringFormat();
format.setSubSuperScript(PdfSubSuperScript.Super_Script);
text = "Superscrip";
page.getCanvas().drawString(text, font, brush, new Point2D.Float(x, y), format);
//Save the document to file
String result="output/superScript.pdf";
doc.saveToFile(result);
}
}

This article demonstrates how to split a worksheet into several Excel documents by using Spire.XLS for Java.
import com.spire.xls.CellRange;
import com.spire.xls.ExcelVersion;
import com.spire.xls.Workbook;
import com.spire.xls.Worksheet;
public class SplitWorksheet {
public static void main(String[] args) {
//Create a Workbook object to load the original Excel document
Workbook bookOriginal = new Workbook();
bookOriginal.loadFromFile("C:\\Users\\Administrator\\Desktop\\Emplyees.xlsx");
//Get the first worksheet
Worksheet sheet = bookOriginal.getWorksheets().get(0);
//Get the header row
CellRange headerRow = sheet.getCellRange(1, 1, 1, 5);
//Get two cell ranges
CellRange range1 = sheet.getCellRange(2, 1, 6, 5);
CellRange range2 = sheet.getCellRange(7, 1, 11, 5);
//Create a new workbook
Workbook newBook1 = new Workbook();
//Copy the header row and range 1 to the new workbook
sheet.copy(headerRow, newBook1.getWorksheets().get(0), 1, 1, true, false);
sheet.copy(range1, newBook1.getWorksheets().get(0), 2, 1, true, false);
//Copy the column width from the original workbook to the new workbook
for (int i = 0; i < sheet.getLastColumn(); i++) {
newBook1.getWorksheets().get(0).setColumnWidth(i + 1, sheet.getColumnWidth(i + 1));
}
//Save the new workbook to an Excel file
newBook1.saveToFile("Sales.xlsx", ExcelVersion.Version2016);
//Copy the header row and range 2 to another workbook, and save it to another Excel file
Workbook newBook2 = new Workbook();
sheet.copy(headerRow, newBook2.getWorksheets().get(0), 1, 1, true, false);
sheet.copy(range2, newBook2.getWorksheets().get(0), 2, 1, true, false);
for (int i = 0; i < sheet.getLastColumn(); i++) {
newBook2.getWorksheets().get(0).setColumnWidth(i + 1, sheet.getColumnWidth(i + 1));
}
newBook2.saveToFile("Technicians.xlsx", ExcelVersion.Version2016);
}

Normally, the default page size of a Word document is “Letter” (8.5 x 11 inches), and the default page orientation is “Portrait”. In most cases, the general page setup can meet the needs of most users, but sometimes you may also need to adjust the page size and orientation to design a different document such as an application form, certificate, or brochure. In this article, you will learn how to programmatically change the page size and page orientation in a Word document using Spire.Doc for Java.
Install Spire.Doc for Java
First of all, 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>
<url>https://repo.e-iceblue.com/nexus/content/groups/public/</url>

<dependencies>
<dependency>
<groupId>e-iceblue</groupId>
<artifactId>spire.doc</artifactId>
<version>14.1.3</version>
</dependency>
</dependencies>
Change Page Size and Page Orientation in Word
The detailed steps are as follows:
- Create a Document instance.
- Load a sample Word document using Document.loadFromFile() method.
- Get the first section using Document.getSections().get() method.
- Change the default page size using Section.getPageSetup().setPageSize() method.
- Change the default page orientation using Section.getPageSetup().setOrientation() method.
- Save the document to file using Document.saveToFile() method.
- Java
import com.spire.doc.*;
import com.spire.doc.documents.*;
public class WordPageSetup {
public static void main(String[] args) throws Exception {
//Create a Document instance
Document doc= new Document();
//Load a sample Word document
doc.loadFromFile("sample.docx");
//Get the first section
Section section = doc.getSections().get(0);
//Change the page size to A3
section.getPageSetup().setPageSize(PageSize.A3);
//Change the page orientation to Landscape
section.getPageSetup().setOrientation(PageOrientation.Landscape);
//Save the document to file
doc.saveToFile("Result.docx",FileFormat.Docx_2013);
}
}
