IntBuffer slice() method in Java

  • Last Updated : 05 Aug, 2021

The slice() method of java.nio.IntBuffer Class is used to creates a new int buffer whose content is a shared subsequence of the given buffer’s content.

The content of the new buffer will start at this buffer’s current position. 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 position will be zero, its capacity and its limit will be the number of integers remaining in this buffer, and its mark will be undefined. 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.

Syntax: 

public abstract IntBuffer slice()

Return Value: This method returns the new int buffer.



Below are the examples to illustrate the slice() method:

Examples 1: 

Java




// Java program to demonstrate
// slice() method
 
import java.nio.*;
import java.util.*;
 
public class GFG {
 
    public static void main(String[] args)
    {
 
        // Declaring the capacity of the IntBuffer
        int capacity = 10;
 
        // Creating the IntBuffer
        try {
 
            // creating object of intbuffer
            // and allocating size capacity
            IntBuffer ib1 = IntBuffer.allocate(capacity);
 
            // putting the value in intbuffer
            ib1.put(8);
            ib1.put(9);
 
            // print the IntBuffer
            System.out.println("Original IntBuffer: "
                               + Arrays.toString(ib1.array()));
 
            // print the IntBuffer position
            System.out.println("position: " + ib1.position());
 
            // print the IntBuffer capacity
            System.out.println("capacity: " + ib1.capacity());
 
            // Creating a shared subsequence buffer of given IntBuffer
            // using slice() method
            IntBuffer ib2 = ib1.slice();
 
            // print the shared subsequence buffer
            System.out.println("shared subsequence IntBuffer: "
                               + Arrays.toString(ib2.array()));
 
            // print the IntBuffer position
            System.out.println("position: " + ib2.position());
 
            // print the IntBuffer capacity
            System.out.println("capacity: " + ib2.capacity());
        }
 
        catch (IllegalArgumentException e) {
            System.out.println("IllegalArgumentException catched");
        }
 
        catch (ReadOnlyBufferException e) {
            System.out.println("ReadOnlyBufferException catched");
        }
    }
}
Output
Original IntBuffer: [8, 9, 0, 0, 0, 0, 0, 0, 0, 0]
position: 2
capacity: 10
shared subsequence IntBuffer: [8, 9, 0, 0, 0, 0, 0, 0, 0, 0]
position: 0
capacity: 8

            ib1.put(5);
            ib1.put(3);

            System.out.println("capacity: " + ib2.capacity());
        }
 
        catch (IllegalArgumentException e) {
 
            System.out.println("IllegalArgumentException catched");
        }
 
        catch (ReadOnlyBufferException e) {
 
            System.out.println("ReadOnlyBufferException catched");
        }
    }
}
Output
Original IntBuffer: [8, 9, 5, 3, 0, 0, 0, 0, 0, 0]
position: 4
capacity: 10
shared subsequence IntBuffer: [8, 9, 5, 3, 2, 6, 0, 0, 0, 0]
position: 2
capacity: 6
