CharBuffer slice() method in Java

A new CharBuffer with the content as a shared subsequence of the original CharBuffer can be created using the method slice() in the class java.nio.CharBuffer. This method returns the new CharBuffer that is read-only if the original buffer is read-only and direct if the original buffer is direct.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.nio.*; import java.util.*; public class Demo {    public static void main(String[] args) {       int n = 5;       try {          CharBuffer buffer1 = CharBuffer.allocate(n);          buffer1.put('A');          buffer1.put('B');          buffer1.put('C');          System.out.println("The Original CharBuffer is: " + Arrays.toString(buffer1.array()));          System.out.println("The position is: " + buffer1.position());          System.out.println("The limit is: " + buffer1.limit());          CharBuffer buffer2 = buffer1.slice();          System.out.println("\nThe Subsequence CharBuffer is: " + Arrays.toString(buffer2.array()));          System.out.println("The position is: " + buffer2.position());          System.out.println("The limit is: " + buffer2.limit());       } catch (IllegalArgumentException e) { System.out.println("Error!!! IllegalArgumentException"); } catch (ReadOnlyBufferException e) { System.out.println("Error!!! ReadOnlyBufferException"); } } }

Output

The Original CharBuffer is: [A, B, C, , ] The position is: 3 The limit is: 5 The Subsequence CharBuffer is: [A, B, C, , ] The position is: 0 The limit is: 2
