This article will demonstrate how to set the zoom factor/percentage (such as default, 100 percent or any other zoom factors as required) and the viewer preference by using Spire.PDF for Java in Java applications.
Set the zoom factor
import com.spire.pdf.*;
import com.spire.pdf.actions.*;
import com.spire.pdf.general.*;
import java.awt.geom.*;
public class setZoomFactor {
public static void main(String[] args) {
//Load the sample document
PdfDocument doc = new PdfDocument();
doc.loadFromFile("Sample.pdf");
//Get the first page of PDF
PdfPageBase page = doc.getPages().get(0);
//Set pdf destination
PdfDestination dest = new PdfDestination(page);
dest.setMode(PdfDestinationMode.Location);
dest.setLocation(new Point2D.Float(-40f, -40f));
//Set zoom factor
dest.setZoom(0.8f);
//Set action
PdfGoToAction gotoAction = new PdfGoToAction(dest);
doc.setAfterOpenAction(gotoAction);
//Save pdf document
String output = "output/setZoomFactor.pdf";
doc.saveToFile(output);
}
}
Output:

Set the viewer preference
import com.spire.pdf.*;
public class viewerPreference {
public static void main(String[] args) {
//Load the sample document
PdfDocument doc = new PdfDocument();
doc.loadFromFile("Sample.pdf");
//Set viewer reference
doc.getViewerPreferences().setCenterWindow(true);
doc.getViewerPreferences().setDisplayTitle(false);
doc.getViewerPreferences().setFitWindow(false);
doc.getViewerPreferences().setHideMenubar(true);
doc.getViewerPreferences().setHideToolbar(true);
doc.getViewerPreferences().setPageLayout(PdfPageLayout.Two_Column_Left);
//Save pdf document
String output = "output/viewerPreference.pdf";
doc.saveToFile(output);
}
}

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);
}
}
Effective screenshot:

Draw Subscript Text
import com.spire.pdf.*;
import com.spire.pdf.graphics.*;
import java.awt.*;
import java.awt.geom.*;
public class PdfSubscriptText {
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 Subscript
PdfStringFormat format = new PdfStringFormat();
format.setSubSuperScript(PdfSubSuperScript.Sub_Script);
text = "Subscrip";
page.getCanvas().drawString(text, font, brush, new Point2D.Float(x, y), format);
//Save the document to file
String result="output/subScript.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);
}
}
