    [Java Tutorial #2] Convert small or large text files to PDF

    Hi,


    In my last Tutorial I shared the java code for adding Image in a table cell of pdf document. Today I will be sharing code for converting small or large text files to pdf in java. Many few libraries are available online that allow users to perform this operation. As I told in my last tutorial that I use Aspose PDFJava Library for managing my PDF files and I am using this library also for conversion, you can use library of your own choice or can use the code in your application. You will find two sets of code below, one for converting small text file and second for converting large text files.

    Convering Text file to PDF
    Code:
    try{
    
       StringBuffer sb = new StringBuffer(1024);
       BufferedReader reader = new BufferedReader(new FileReader("test.txt"));
                                        
       int ch = -1;
    
       while( (ch = reader.read()) > -1){
          sb.append((char)ch);      
       }
    
       reader.close();
    
       	//Instantiate Pdf pbject by calling its empty constructor
       	Pdf pdf1 = new Pdf();
    
      	//Create a new section in the Pdf object
     	Section sec1 = pdf1.getSections().add();
    
     	//Create a new text paragraph and pass the text to its constructor as argument
     	Text text1 = new Text(sec1,sb.toString());
    
     	sec1.getParagraphs().add(text1);
                                        
     	pdf1.save("d:/pdftest/Text_File_to_PDF.pdf");	
    
    }catch(java.io.IOException ioe){
       System.out.println(ioe.getMessage());
    }
    Converting Large Text files to PDF
    Code:
    try{
    //Instantiate Pdf pbject by calling its empty constructor
    Pdf pdf1 = new Pdf();        
    //Create a new section in the Pdf object
    Section sec1 = pdf1.getSections().add();
    
    // Open the file that is the first 
    // command line parameter
    FileInputStream fstream = new FileInputStream("d:/pdftest/LargeText.txt");
        	// Get the object of DataInputStream
        	DataInputStream in = new DataInputStream(fstream);
            BufferedReader br = new BufferedReader(new InputStreamReader(in));
        	String strLine;
        	//Read File Line By Line
    while ((strLine = br.readLine()) != null)   
    {
     	//Create a new text paragraph and pass the text to its constructor as argument
      	Text text1 = new Text(sec1,strLine);
       	sec1.getParagraphs().add(text1);
    }
    
     	//Close the input stream
        	in.close();
    
            // Save the PDF file
            pdf1.save("d:/pdftest/LargeText.pdf");
    
        }catch(java.io.IOException ioe){
           System.out.println(ioe.getMessage());
          }catch(Exception e){
           System.out.println(e.getMessage());
          }

    Try the above code and share your views about the code.
