  import java.io.File;
  import java.io.FileOutputStream;
  import java.io.IOException;
  import org.apache.poi.xslf.usermodel.SlideLayout;
  import org.apache.poi.xslf.usermodel.XMLSlideShow;
  import org.apache.poi.xslf.usermodel.XSLFSlide;
  import org.apache.poi.xslf.usermodel.XSLFSlideLayout;
  import org.apache.poi.xslf.usermodel.XSLFSlideMaster;
  import org.apache.poi.xslf.usermodel.XSLFTextParagraph;
  import org.apache.poi.xslf.usermodel.XSLFTextRun;
  import org.apache.poi.xslf.usermodel.XSLFTextShape;
  public class FormatTextPPT {
     public static void main(String args[]) throws IOException {
        //creating an empty presentation
        XMLSlideShow ppt = new XMLSlideShow();
        //getting the slide master object
        XSLFSlideMaster slideMaster = ppt.getSlideMasters()[0];
        //select a layout from specified list
        XSLFSlideLayout slidelayout = slideMaster.getLayout(SlideLayout.TITLE_AND_CONTENT);
        //creating a slide with title and content layout
        XSLFSlide slide = ppt.createSlide(slidelayout);
        //selection of title place holder
        XSLFTextShape body = slide.getPlaceholder(1);
        //clear the existing text in the slide
        body.clearText();
        //adding new paragraph
        XSLFTextParagraph paragraph = body.addNewTextParagraph();
        //formatting line 1
        XSLFTextRun run1 = paragraph.addNewTextRun();
        run1.setText("This is a colored line");
        //setting color to the text
        run1.setFontColor(java.awt.Color.red);
        //setting font size to the text
        run1.setFontSize(24);
        //moving to the next line
        paragraph.addLineBreak();
        //formatting line 2
        XSLFTextRun run2 = paragraph.addNewTextRun();
        run2.setText("This is a bold line");
        run2.setFontColor(java.awt.Color.CYAN);
        //making the text bold
        run2.setBold(true);
        paragraph.addLineBreak();
        //formatting line 3
        XSLFTextRun run3 = paragraph.addNewTextRun();
        run3.setText(" This is a striked line");
        run3.setFontSize(12);
        //making the text italic
        run3.setItalic(true);
        //strike through the text
        run3.setStrikethrough(true);
        paragraph.addLineBreak();
        //formatting line 4
        XSLFTextRun run4 = paragraph.addNewTextRun();
        run4.setText(" This an underlined line");
        run4.setUnderline(true);
        //underlining the text
        paragraph.addLineBreak();
        //creating a file object
        File file = new File("C:/poippt/FormatedText.pptx");
        FileOutputStream out = new FileOutputStream(file);
        //saving the changes to a file
        ppt.write(out);
        out.close();
        System.out.println("PPT created");
     }
  }
