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");
   }
}
