ShortBuffer asReadOnlyBuffer() method in Java
A read-only short buffer can be created using the contents of a buffer with the method asReadOnlyBuffer() in the class java.nio.ShortBuffer. The new buffer cannot have any modifications as it is a read-only buffer. However, the capacity, positions, limits etc. of the new buffer are the same as the previous buffer.
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 {
ShortBuffer buffer = ShortBuffer.allocate(5);
buffer.put((short)12);
buffer.put((short)91);
buffer.put((short)25);
buffer.put((short)18);
buffer.put((short)30);
buffer.rewind();
System.out.println("The Original ShortBuffer is: " + Arrays.toString(buffer.array()));
ShortBuffer roBuffer = buffer.asReadOnlyBuffer();
System.out.println("The ReadOnlyBuffer ShortBuffer is: ");
while (roBuffer.hasRemaining())
System.out.print(roBuffer.get() + " ");
} 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 ShortBuffer is: [12, 91, 25, 18, 30] The ReadOnlyBuffer ShortBuffer is: 12 91 25 18 30
