CharBuffer duplicate() method in Java
The duplicate() method of java.nio.CharBuffer Class is used to Create a new char buffer that shares the given buffer’s content.
The content of the new buffer will be that of this buffer. Changes 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 capacity, limit, position, and mark values will be identical to those of this buffer. 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.
public abstract CharBuffer duplicate()
Return Value: This method returns the new char buffer which is carrying the previous char buffer content
Below are the examples to illustrate the duplicate() method:
Example 1: Using direct charbuffer
Original CharBuffer: [a, , b, , , , , , , ] Duplicate CharBuffer: [a, , b, , , , , , , ]
Example 2: Using read-onlyintbuffer
Original CharBuffer: [a, , b, , , , , , , ] read-only CharBuffer: a, , b, , , , , , , , duplicate copy of read-only CharBuffer: a, , b, , , , , , , ,
