Last Updated :

The flip() method of java.nio.LongBuffer Class is used to flip this buffer. By flipping this buffer, it meant that
- the buffer will be trimmed to the current position
- the then the position will be changed to zero
- if any mark is there on the buffer, then that mark will be automatically discarded
Syntax:
public final LongBuffer flip()
Parameter: This method do not accept any parameter.
Return Value: This method returns the flipped LongBuffer instance.
Below are the examples to illustrate the flip() method:
Examples 1:
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
long [] db
= { 10 , 20 , 30 };
LongBuffer longBuffer
= LongBuffer.wrap(db);
longBuffer.position( 1 );
System.out.println(
"Buffer before flip: "
+ Arrays.toString(
longBuffer.array())
+ "\nPosition: "
+ longBuffer.position()
+ "\nLimit: "
+ longBuffer.limit());
longBuffer.flip();
System.out.println(
"\nBuffer after flip: "
+ Arrays.toString(
longBuffer.array())
+ "\nPosition: "
+ longBuffer.position()
+ "\nLimit: "
+ longBuffer.limit());
}
}
|
Output:
Buffer before flip: [10, 20, 30]
Position: 1
Limit: 3
Buffer after flip: [10, 20, 30]
Position: 0
Limit: 1
Examples 2:
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
LongBuffer longBuffer
= LongBuffer.allocate( 4 );
longBuffer.put( 20 );
longBuffer.put( 34 );
longBuffer.position( 1 );
System.out.println(
"Buffer before flip: "
+ Arrays.toString(
longBuffer.array())
+ "\nPosition: "
+ longBuffer.position()
+ "\nLimit: "
+ longBuffer.limit());
longBuffer.flip();
System.out.println(
"\nBuffer after flip: "
+ Arrays.toString(
longBuffer.array())
+ "\nPosition: "
+ longBuffer.position()
+ "\nLimit: "
+ longBuffer.limit());
}
}

Output:
Buffer before flip: [20, 34, 0, 0]
Position: 1
Limit: 4
Buffer after flip: [20, 34, 0, 0]
Position: 0
Limit: 1
