Body
copied!<p>I want to write string/Char data as bytes in a file.I want this conversion happen internally in IO.* classes. I do not want to use getBytes() method on string.</p> <p>I tried following two Programs but both are writing data as Character . And when i open the file in notepad i can read these characters. How can i store my data as bytes ?</p> <pre><code> import IO.FileWrite; import java.io.*; public class CharToChar { private final String data; public CharToChar(String data){ this.data = data; } public static void main(String[] args) throws IOException { final CharToChar charToChar = new CharToChar("I am Manish"); charToChar.write(); } private void write() throws IOException { final File file = new File("CharToChar.txt"); final FileWriter fileWriter = new FileWriter(file); final BufferedWriter bufferdWriter = new BufferedWriter(fileWriter); bufferdWriter.write(this.data); bufferdWriter.close(); } } import java.io.DataOutputStream; import java.io.FileOutputStream; import java.io.IOException; public class WriteStringAsBytesToFile { public static void main(String[] args) { String strFilePath = "WriteStringAsBytes.txt"; try { //create FileOutputStream object FileOutputStream fos = new FileOutputStream(strFilePath); /* * To create DataOutputStream object from FileOutputStream use, * DataOutputStream(OutputStream os) constructor. * */ DataOutputStream dos = new DataOutputStream(fos); String str = "This string will be written to file as sequence of bytes!"; /* * To write a string as a sequence of bytes to a file, use * void writeBytes(String str) method of Java DataOutputStream class. * * This method writes string as a sequence of bytes to underlying output * stream (Each character's high eight bits are discarded first). */ dos.writeBytes(str); /* * To close DataOutputStream use, * void close() method. * */ dos.close(); } catch (IOException e) { System.out.println("IOException : " + e); } } } </code></pre> <p>Note - > JAVA docs says OutputStreamWriter An OutputStreamWriter is a bridge from character streams to byte streams: * Characters written to it are encoded into bytes using a specified.</p>
