LongBuffer slice() method in Java
Last Updated :
04 Jul, 2022
The slice() method of java.nio.LongBuffer Class is used to creates a new Long 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 Long 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 LongBuffer slice()
Return Value: This method returns the new Long buffer.
Below are the examples to illustrate the slice() method:
Example 1:
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 10 ;
try {
LongBuffer ib1 = LongBuffer.allocate(capacity);
ib1.put( 8 );
ib1.put( 9 );
System.out.println( "Original LongBuffer: "
+ Arrays.toString(ib1.array()));
System.out.println( "position: " + ib1.position());
System.out.println( "capacity: " + ib1.capacity());
LongBuffer ib2 = ib1.slice();
System.out.println( "shared subsequence LongBuffer: "
+ Arrays.toString(ib2.array()));
System.out.println( "position: " + ib2.position());
System.out.println( "capacity: " + ib2.capacity());
}
catch (IllegalArgumentException e) {
System.out.println( "IllegalArgumentException catched" );
}
catch (ReadOnlyBufferException e) {
System.out.println( "ReadOnlyBufferException catched" );
}
}
}
|
Output
Original LongBuffer: [8, 9, 0, 0, 0, 0, 0, 0, 0, 0]
position: 2
capacity: 10
shared subsequence LongBuffer: [8, 9, 0, 0, 0, 0, 0, 0, 0, 0]
position: 0
capacity: 8
Example 2:
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 10 ;
try {
LongBuffer ib1 = LongBuffer.allocate(capacity);
ib1.put( 8 );
ib1.put( 9 );
ib1.put( 5 );
ib1.put( 3 );
System.out.println( "Original LongBuffer: "
+ Arrays.toString(ib1.array()));
System.out.println( "position: " + ib1.position());
System.out.println( "capacity: " + ib1.capacity());
LongBuffer ib2 = ib1.slice();
ib2.put( 2 );
ib2.put( 6 );
System.out.println( "shared subsequence LongBuffer: "
+ Arrays.toString(ib2.array()));
System.out.println( "position: " + ib2.position());
System.out.println( "capacity: " + ib2.capacity());
}
catch (IllegalArgumentException e) {
System.out.println( "IllegalArgumentException catched" );
}
catch (ReadOnlyBufferException e) {
System.out.println( "ReadOnlyBufferException catched" );
}
}
}

Output
Original LongBuffer: [8, 9, 5, 3, 0, 0, 0, 0, 0, 0]
position: 4
capacity: 10
shared subsequence LongBuffer: [8, 9, 5, 3, 2, 6, 0, 0, 0, 0]
position: 2
capacity: 6
