DoubleBuffer duplicate() method in Java
A duplicate buffer of a buffer can be created using the method duplicate() in the class java.nio.DoubleBuffer. This duplicate buffer is identical to the original buffer. The method duplicate() returns the duplicate buffer that was created.
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 {
DoubleBuffer buffer1 = DoubleBuffer.allocate(5);
buffer1.put(4.5D);
buffer1.put(1.2D);
buffer1.put(3.9D);
buffer1.put(7.5D);
buffer1.put(5.8D);
buffer1.rewind();
System.out.println("The Original DoubleBuffer is: " + Arrays.toString(buffer1.array()));
DoubleBuffer buffer2 = buffer1.duplicate();
System.out.print("The Duplicate DoubleBuffer is: " + Arrays.toString(buffer2.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 Original DoubleBuffer is: [4.5, 1.2, 3.9, 7.5, 5.8] The Duplicate DoubleBuffer is: [4.5, 1.2, 3.9, 7.5, 5.8]
