FloatBuffer hasArray() method in Java
It can be checked if a buffer has the backing of an accessible float array by using the method hasArray() in the class java.nio.FloatBuffer. This method returns true if the buffer has the backing of an accessible float array and false otherwise.
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 = 5;
try {
FloatBuffer buffer = FloatBuffer.allocate(5);
buffer.put(4.5F);
buffer.put(1.2F);
buffer.put(3.9F);
buffer.put(7.5F);
buffer.put(5.8F);
buffer.rewind();
System.out.println("The FloatBuffer is: " + Arrays.toString(buffer.array()));
boolean flag = buffer.hasArray();
if (flag)
System.out.println("The FloatBuffer is backed by an array");
else
System.out.println("The FloatBuffer is not backed by any array");
} catch (IllegalArgumentException e) {
System.out.println("Error!!! IllegalArgumentException");
} catch (ReadOnlyBufferException e) {
System.out.println("Error!!! ReadOnlyBufferException");
}
}
}The output of the above program is as follows −
Output
The FloatBuffer is: [4.5, 1.2, 3.9, 7.5, 5.8] The FloatBuffer is backed by an array
