DoubleBuffer slice() method in Java with Examples
The slice() method of java.nio.DoubleBuffer Class is used to creates a new double 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 doubles 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 DoubleBuffer slice()
Return Value: This method returns the new double buffer.
Below are the examples to illustrate the slice() method:
Examples 1:
// 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 DoubleBuffer int capacity = 10 ; // Creating the DoubleBuffer try { // creating object of Doublebuffer // and allocating size capacity DoubleBuffer fb1 = DoubleBuffer.allocate(capacity); // putting the value in Doublebuffer fb1.put( 8 .56F); fb1.put( 9 .61F); // print the DoubleBuffer System.out.println( "Original DoubleBuffer: " + Arrays.toString(fb1.array())); // print the DoubleBuffer position System.out.println( "\nposition: " + fb1.position()); // print the DoubleBuffer capacity System.out.println( "\ncapacity: " + fb1.capacity()); // Creating a shared subsequance buffer of given DoubleBuffer // using slice() method DoubleBuffer fb2 = fb1.slice(); // print the shared subsequance buffer System.out.println( "\nshared subsequance DoubleBuffer: " + Arrays.toString(fb2.array())); // print the DoubleBuffer position System.out.println( "\nposition: " + fb2.position()); // print the DoubleBuffer capacity System.out.println( "\ncapacity: " + fb2.capacity()); } catch (IllegalArgumentException e) { System.out.println( "IllegalArgumentException catched" ); } catch (ReadOnlyBufferException e) { System.out.println( "ReadOnlyBufferException catched" ); } } } |
