Use of putChar() method of ByteBuffer class.

 In this tutorial, we will see how to write the given character into byte buffer.

ByteBuffer API:

The java.nio.ByteBuffer class extends java.nio.Buffer class. It provides the following methods:

Return type Method Description
static ByteBuffer allocate( int capacity)  The allocate(..)method allocate a new byte buffer.
abstract ByteBuffer putChar(char value) The putChar(..) method write two byte containing the given character value into associated buffer.
abstract char getChar() The getChar() method read  2 byte from current position and increment position.

code

import java.nio.*;
import java.nio.ByteBuffer;

public class BytePutChar {
  public static void main(String[] args) {
    ByteBuffer bytebuf = ByteBuffer.allocate(256);
    bytebuf.putChar('B');
    bytebuf.putChar('h');
    bytebuf.putChar('a');
    bytebuf.putChar('r');
    bytebuf.putChar('a');
    bytebuf.putChar('t');
    System.out.println(bytebuf);
    bytebuf.flip();
System.out.println("Character data in byte buffer :");
    while (bytebuf.hasRemaining()) {
      System.out.print(bytebuf.getChar());
    }
  }
}

Output

:\>java BytePutChar
java.nio.HeapByteBuffer[pos=12 lim=256 cap=256]
Character data in byte buffer :
