How to read a data text file into the java font encoder?

We have a text file with data that we need to encode as Code 128 using your java font encoder. How do I pass my data to the encoder? Can you provide a very basic example?

The example describes how to encode the data in a text file by reading it into the java application and pass it to another text file as encoded data.

Download the barcode fonts and java font encoder.
Set up the environment so that it can use the IDAutomation java font encoder class.



STEP 1
To read/encode a data text file into a java application and receive the encoded output, create two text files:

data.txt (the file that has the data to encode)
encodeddata.txt (the file that will receive the encoded data)

STEP 2
Create a bat file that compiles and runs the application. After java [projectname], use the > symbol and the [encodeddata file]. This will pass the System.out.println data to this file once the reader is set up.

Example

javac C:classpathBarcodeProjectBarcode1.java
java Barcode1 > encodeddata.txt
Pause



STEP 3
Add File streaming to application/project.

(text example of code)
import java.io.*;
import com.idautomation.*;

class Barcode1
{
public static void main ( String [] args )

{
try
{
// Open the file that is the first
FileInputStream fstream = new FileInputStream("data.txt");


//Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));


//Linear Barcode object
LinearFontEncoder FontEncoder = new LinearFontEncoder();

//Set ApplyTilde (When set to True encoodes
boolean ApplyTilde = true;

//Creates the DataToEncode String
String DataToEncode;

//Read File Line By Line
while ((DataToEncode = br.readLine()) != null) {

// Encode the data for Code 128 Auto
System.out.println(FontEncoder.Code128(DataToEncode,ApplyTilde));
}
//Close the input stream
in.close();
}

catch (Exception e)
{
//Catch exception if any
System.err.println("Error: " + e.getMessage());
}

}
}


STEP 4
Run the application and after it completes, open the encodeddata file.
