java - Read and Write Text in ANSI format

Question

Please have a look at the following code

import java.io.*;

public class CSVConverter 
{
    private File csvFile;
    private BufferedReader reader;
    private StringBuffer strBuffer;
    private BufferedWriter writer;
    int startNumber = 0;
    private String strString[];

    public CSVConverter(String location, int startNumber)
    {
        csvFile = new File(location);
        strBuffer = new StringBuffer("");
        this.startNumber = startNumber;


        //Read
        try
        {
         reader = new BufferedReader(new FileReader(csvFile));
         String line = "";

         while((line=reader.readLine())!=null)
         {
             String[] array = line.split(",");

             String inputQuery = "insertQuery["+startNumber+"] = "insert into WordList_Table ('Engl','Port','EnglishH','PortugueseH','Numbe','NumberOf','NumberOfTime','NumberOfTimesPor')values('"+array[0]+"','"+array[2]+"','"+array[1]+"','"+array[3]+"',0,0,0,0)"";

             strBuffer.append(inputQuery+";"+"
");
             startNumber++;

         }
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }

       System.out.println(strBuffer.toString());

        //Write
        try
        {
            File file = new File("C:/Users/list.txt");
            FileWriter filewrite = new FileWriter(file);

            if(!file.exists())
            {
                file.createNewFile();
            }


            writer = new BufferedWriter(filewrite);


            writer.write(strBuffer.toString());
            writer.flush();
            writer.close();

        }
        catch(Exception e)
        {
            e.printStackTrace();
        }

    }

    public static void main(String[]args)
    {
        new CSVConverter("C:/Users/list.csv",90);
    }
}

I am trying to read a CSV file, edit the text in code, and write it back to a .txt file. My issue is, I have Portuguese words, so the file should be read and write using ANSI format. Right now some Portuguese words are replaced with symbols in the output file.

How can I read and write text data into a file in ANSI format in Java?

Answer 1

To read a text file with a specific encoding you can use a FileInputStream in conjunction with a InputStreamReader. The right Java encoding for Windows ANSI is Cp1252.

reader = new BufferedReader(new InputStreamReader(new FileInputStream(csvFile), "Cp1252"));

To write a text file with a specific character encoding you can use a FileOutputStream together with a OutputStreamWriter.

writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(file), "Cp1252"));

The classes InputStreamReader and OutputStreamWriter translate between byte oriented streams and text with a specific character encoding.
