The duplicate() method of java.nio.IntBuffer Class is used to create a new IntBuffer that shares the given buffer’s content, identically in all aspects.
Syntax:
public abstract IntBuffer duplicate()
Return Value: This method returns the new IntBuffer which is carrying the previous IntBuffer’s content
Below are the examples to illustrate the duplicate() method:
Examples 1: Using direct IntBuffer
// Java program to demonstrate duplicate() 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( 2 , 9 );
ib1.rewind();
// print the Original IntBuffer
System.out.println( "Original IntBuffer: "
+ Arrays.toString(ib1.array()));
// Creating a duplicate copy of IntBuffer
// using duplicate() method
IntBuffer ib2 = ib1.duplicate();
// print the duplicate copy of IntBuffer
System.out.print( "Duplicate IntBuffer: "
+ Arrays.toString(ib2.array()));
}
catch (IllegalArgumentException e) {
System.out.println( "IllegalArgumentException catched" );
}
catch (ReadOnlyBufferException e) {
System.out.println( "ReadOnlyBufferException catched" );
}
}
} |
Output:
Original IntBuffer: [8, 0, 9, 0, 0, 0, 0, 0, 0, 0] Duplicate IntBuffer: [8, 0, 9, 0, 0, 0, 0, 0, 0, 0]
Examples 2: Using read-onlyintbuffer
// Java program to demonstrate // duplicate() method // using read-onlyIntbuffer 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( 2 , 9 );
ib1.rewind();
// print the Original IntBuffer
System.out.println( "Original IntBuffer: "
+ Arrays.toString(ib1.array()));
// Creating a read-only copy of IntBuffer
// using asReadOnlyBuffer() method
IntBuffer readonly = ib1.asReadOnlyBuffer();
// print the read-only copy of IntBuffer
System.out.print( "read-only IntBuffer: " );
while (Readonly.hasRemaining())
System.out.print(readonly.get() + ", " );
System.out.println( "" );
// Rewinding the readonly IntBuffer
readonly.rewind();
// Creating a duplicate copy of IntBuffer
// using duplicate() method
IntBuffer ib2 = readonly.duplicate();
// print the duplicate copy of IntBuffer
System.out.print( "Duplicate copy of read-only IntBuffer: " );
while (ib2.hasRemaining())
System.out.print(ib2.get() + ", " );
System.out.println( "" );
}
catch (IllegalArgumentException e) {
System.out.println( "IllegalArgumentException catched" );
}
catch (ReadOnlyBufferException e) {
System.out.println( "ReadOnlyBufferException catched" );
}
}

Output:
Original IntBuffer: [8, 0, 9, 0, 0, 0, 0, 0, 0, 0] Read-only IntBuffer: 8, 0, 9, 0, 0, 0, 0, 0, 0, 0, Duplicate copy of read-only IntBuffer: 8, 0, 9, 0, 0, 0, 0, 0, 0, 0,
