ByteBuffer asFloatBuffer() method in Java with Examples

Last Updated : 3 Jun, 2021

The asFloatBuffer() method of java.nio.ByteBuffer class is used to create view of this byte buffer as a float buffer.
The content of the new buffer will start from this buffer's current position. Changes made to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.
The new buffer's position will be zero, its capacity and its limit will be the number of bytes remaining in this buffer divided by four, and its mark will be undefined. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

Syntax: 

public abstract FloatBuffer asFloatBuffer()

Return Value: This method returns a new float buffer

Below are the examples to illustrate the asFloatBuffer() method:

Examples 1:  


Output: 
FloatBuffer : 1.23 1.33 1.56

 

Examples 2: 


Output: 
FloatBuffer : 2.1 3.1 4.1 

Trying to put the value in read only FloatBuffer
Exception thrown : java.nio.ReadOnlyBufferException
