Java中如何使用iText创建PDF呢？

实现思路:
    实例化一个PdfWriter对象即可将生成PDF文件

package com.java265.other;
import java.io.File; 
import java.io.FileOutputStream; 
import java.io.OutputStream; 
import java.util.Date; 
 
import com.lowagie.text.Document; 
import com.lowagie.text.Paragraph; 
import com.lowagie.text.pdf.PdfWriter; 
 
public class GeneratePDF { 
 
  public static void main(String[] args) { 
    try { 
      OutputStream file = new FileOutputStream(new File("D:\\test\test20211101.pdf")); 
 
      Document document = new Document(); 
      PdfWriter.getInstance(document, file); 
      document.open(); 
      document.add(new Paragraph("Hello Kiran")); 
      document.add(new Paragraph(new Date().toString())); 
 
      document.close(); 
      file.close(); 
 
    } catch (Exception e) { 
 
      e.printStackTrace(); 
    } 
  } 
}
