How to allocate a float buffer in java.

In this tutorial, we will see how to allocate a new float buffer.

FloatBuffer API:

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

Return type	Method	Description
static FloatBuffer	allocate( int capacity)	The allocate() method allocate a float buffer of given capacity.
int	limit()	The limit() method returns the limit of float buffer.
int	position()	The position() method returns the position of float buffer.
final int	capacity()	The capacity() method returns the capacity of associated float buffer.

Code


import java.nio.*;

import java.nio.FloatBuffer;

public class FloatBufferDemo {

public static void main(String[] args) throws Exception {

FloatBuffer floatBuf = FloatBuffer.allocate(500);

System.out.println("Position of FloatBuffer :" 

                                  + floatBuf.position());

System.out.println("Limit of FloatBuffer :" 

                                     + floatBuf.limit());

System.out.println("Capacity of FloatBuffer :"

                                  + floatBuf.capacity());

  }

}

Output

C:\>java FloatBufferDemo
Position of FloatBuffer :0
Limit of FloatBuffer :500
Capacity of FloatBuffer :500
