Convert String from ASCII to EBCDIC in Java?

Question

I need to write a \'simple\' util to convert from ASCII to EBCDIC?

The Ascii is coming from Java, Web and going to an AS400. I\'ve had a google around, can\'t seem

package javaapplication1;

import java.nio.ByteBuffer;
import java.nio.CharBuffer;

import java.nio.charset.CharacterCodingException;

import java.nio.charset.Charset;

import java.nio.charset.CharsetDecoder;

import java.nio.charset.CharsetEncoder;

public class ConvertBetweenCharacterSetEncodingsWithCharBuffer {

    public static void main(String[] args) {

       //String cadena = "@@@@@@@@@@@@@@@ñâæÃÈÄóöó@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ÔÁâãÅÙÃÁÙÄ@ÄÅÂÉã@âæÉãÃÈ@@@@@@@@";
        String cadena = "ñâæÃÈÄóöó";
        System.out.println(Convert(cadena,"CP1047","ISO-8859-1"));
        cadena = "1SWCHD363";
        System.out.println(Convert(cadena,"ISO-8859-1","CP1047"));

    }

    public static String Convert (String strToConvert,String in, String out){
       try {

        Charset charset_in = Charset.forName(out);
        Charset charset_out = Charset.forName(in);

        CharsetDecoder decoder = charset_out.newDecoder();

        CharsetEncoder encoder = charset_in.newEncoder();

        CharBuffer uCharBuffer = CharBuffer.wrap(strToConvert);

        ByteBuffer bbuf = encoder.encode(uCharBuffer);

        CharBuffer cbuf = decoder.decode(bbuf);

        String s = cbuf.toString();

        //System.out.println("Original String is: " + s);
        return s;

    } catch (CharacterCodingException e) {

        //System.out.println("Character Coding Error: " + e.getMessage());
        return "";

    }


}

You should use either the Java character set Cp1047 (Java 5) or Cp500 (JDK 1.3+).

Use the String constructor: String(byte[] bytes, [int offset, int length,] String enc)

Answer 3

This is what I've been using.

public static final int[] ebc2asc = new int[256];
public static final int[] asc2ebc = new int[256];

static
{
  byte[] values = new byte[256];
  for (int i = 0; i < 256; i++)
    values[i] = (byte) i;

  try
  {
    String s = new String (values, "CP1047");
    char[] chars = s.toCharArray ();
    for (int i = 0; i < 256; i++)
    {
      int val = chars[i];
      ebc2asc[i] = val;
      asc2ebc[val] = i;
    }
  }
  catch (UnsupportedEncodingException e)
  {
    e.printStackTrace ();
  }
}

I make a code that transforms data types easily.

public class Converter{

    public static void main(String[] args) {

        Charset charsetEBCDIC = Charset.forName("CP037");
        Charset charsetACSII = Charset.forName("US-ASCII");

        String ebcdic = "(((((((";
        System.out.println("String EBCDIC: " + ebcdic);
        System.out.println("String converted to ASCII: " + convertTO(ebcdic, charsetEBCDIC, charsetACSII));

        String ascII = "MMMMMM";
        System.out.println("String ASCII: " + ascII);
        System.out.println("String converted to EBCDIC: " + convertTO(ascII, charsetACSII, charsetEBCDIC));
    }

    public static String convertTO(String dados, Charset encondingFrom, Charset encondingTo) {
        return new String(dados.getBytes(encondingFrom), encondingTo);
    }
}
