public class FormatTextInPdf { 
   public static void main(String args[]) throws Exception { 
      String file = "C:/EXAMPLES/itextExamples/formatingTextInPDF.pdf"; 
      
      //创建一个 PdfDocument 对象
      PdfDocument pdfDoc = new PdfDocument(new PdfWriter(file));     

      //创建一个文档对象
      Document doc = new Document(pdfDoc);        

      //向文档添加文本
      Text text1 = new Text("Tutorials Point originated from the idea that there exists
         a class of readers who respond better to online content and prefer to
         learn new skills at their own pace from the comforts of their drawing rooms.");

      //设置文本颜色
      text1.setFontColor(Color.RED); 

      //设置文本的字体
      text1.setFont(PdfFontFactory.createFont(FontConstants.HELVETICA)); 
      
      //创建段落 1
      Paragraph para1 = new Paragraph(text1); 

      Text text2 = new Text("The journey commenced with a single tutorial on HTML in 2006
         and elated by the response it generated, we worked our way to adding fresh
         tutorials to our repository which now proudly flaunts a wealth of tutorials and
         allied articles on topics ranging from programming languages to web designing to
         academics and much more.");  
      
      //设置文本颜色

      //设置文本的字体
      text2.setFont(PdfFontFactory.createFont(FontConstants.HELVETICA)); 

      //创建段落 2
      Paragraph para2 = new Paragraph(text2); 

      //向文档添加段落
      doc.add(para1); 
      doc.add(para2); 

      //关闭文档
      doc.close(); 
      System.out.println("Text added successfully..");
