Compare a float buffer with another float buffer.

In this tutorial, we will see how to compare a float buffer with another float buffer.

FloatBuffer API:

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

Return type	Method	Description
staticFloatBuffer	allocate(int capacity)	The allocate(..)method allocate a new float buffer.
int	compareTo(FloatBuffer buffer)	The compareTo() method returns 0, -1 or 1. It means this buffer is equal, less and greater than to another buffer.
abstract FloatBuffer	put(float f)	The put(..) method write a given float value at the current position.

code


import java.nio.*;

import java.nio.FloatBuffer;



public class FloatCompareDemo {

public static void main(String[] args){

    FloatBuffer floatBuf = FloatBuffer.allocate(256);

    floatBuf.put(4.2f);

    floatBuf.put(5.1f);

    floatBuf.put(6.4f);

    FloatBuffer floatBuf1 = FloatBuffer.allocate(256);

    floatBuf1.put(98.54f);

    floatBuf1.put(5.3f);

    int i=floatBuf.compareTo(floatBuf1);

    System.out.println(i);    

    FloatBuffer floatBuf2 = FloatBuffer.allocate(256);

    floatBuf2.put(76.45f);

    floatBuf2.put(98.32f);

    int i1=floatBuf2.compareTo(floatBuf1);

    System.out.println(i1);

    int i2=floatBuf2.compareTo(floatBuf);

    System.out.println(i2);

    }

  }

Output

C:\>java FloatCompareDemo
