ByteBuffer asFloatBuffer() method in Java
A view of the ByteBuffer can be created as a FloatBuffer using the asFloatBuffer() method in the class java.nio.ByteBuffer. This method requires no parameters and it returns a float buffer as required. This buffer reflects the changes made to the original buffer and vice versa.
A program that demonstrates this is given as follows −
Example
import java.nio.*;
import java.util.*;
public class Demo {
public static void main(String[] args) {
int n = 50;
try {
ByteBuffer bufferB = ByteBuffer.allocate(n);
FloatBuffer bufferF = bufferB.asFloatBuffer();
bufferF.put(3.5F);
bufferF.put(9.7F);
bufferF.put(1.2F);
bufferF.put(7.5F);
bufferF.put(4.6F);
bufferF.rewind();
float f;
System.out.print("The FloatBuffer is: ");
while ((f = bufferF.get()) != 0) {
System.out.print(f + " ");
}
} catch (IllegalArgumentException e) {
System.out.println("Error!!! IllegalArgumentException");
} catch (ReadOnlyBufferException e){
System.out.println("Error!!! ReadOnlyBufferException");
}
}
}Output
The FloatBuffer is: 3.5 9.7 1.2 7.5 4.6
