Use of getFloat() method of ByteBuffer class in java.

 In this tutorial, we will see how to read float value from a 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 putFloat() The putFloat(..) method write four byte containing the given float value into associated buffer.
abstract float getFloat() The getFloat() method read four byte from current position and increment position by four.

code

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

public class GetFloatValue {
  public static final int capacity = 100;
  public static void main(String[] argv) throws Exception {
    ByteBuffer bytebuf = ByteBuffer.allocate(capacity);
    bytebuf.putFloat(221255.02F);
    bytebuf.flip();
    System.out.println("Float data into byte buffer : "
        + bytebuf.getFloat());
  }
}

Output

C:\>java GetFloatValue
Float data into byte buffer : 221255.02
