Use of hashCode method of FloatBuffer class in java.

In this tutorial, we will see the use of hashCode() method of FloatBuffer class in java.

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 hashCode() The hashCode() method returns current has code of float buffer. It depends upon remaining elements.  

Code

import java.nio.*;
import java.nio.FloatBuffer;

public class BufferHasCode {
  public static final int capacity = 256;
    public static void main(String[] arg) {
    FloatBuffer f = FloatBuffer.allocate(capacity);
System.out.println("hashCode of empty buffer :" + f.hashCode());
    f.put(22.45f);
    f.put(2.45f);
  System.out.println("hashCode of buffer : " + f.hashCode());
  }
}

Output

C:\>java BufferHasCode
hashCode of empty buffer: -394403839
hashCode of buffer : 2059922497
