NIO: Convert CharBuffer to ByteBuffer

Charset is used to convert ByteBuffer to CharBuffer and vice versa.

'encode' method of Charset class is used to convert a CharBuffer to ByteBuffer.

Example

CharBuffer charBuffer = CharBuffer.wrap("Hello World");

ByteBuffer byteBuffer = Charset.forName("utf-8").encode(charBuffer);

Test.java

package com.sample.app;

import java.io.IOException;
import java.nio.ByteBuffer;
import java.nio.CharBuffer;
import java.nio.charset.Charset;

public class Test {

 public static void main(String... args) throws IOException {
  CharBuffer charBuffer = CharBuffer.wrap("Hello World");
  ByteBuffer byteBuffer = Charset.forName("utf-8").encode(charBuffer);

  for (byte data : byteBuffer.array()) {
   System.out.print(data + " ");
  }

  System.out.println();
 }
}

Output

72 101 108 108 111 32 87 111 114 108 100 0
