FloatBuffer flip() methods in Java with Examples
Last Updated :

The flip() method of java.nio.FloatBuffer Class is used to flip this buffer. By flipping this buffer, it meant that the buffer will be trimmed to the current position and then the position will be changed to zero. During this process, if any mark is there on the buffer, then that mark will be automatically discarded.
Syntax:
public final FloatBuffer flip()
Return Value: This method returns the flipped FloatBuffer instance.
Below are the examples to illustrate the flip() method:
Examples 1:
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
float [] db
= { 10 .56f, 20 .34f, 30 .78f };
FloatBuffer floatBuffer
= FloatBuffer.wrap(db);
floatBuffer.position( 1 );
System.out.println(
"Buffer before flip: "
+ Arrays.toString(
floatBuffer.array())
+ "\nPosition: "
+ floatBuffer.position()
+ "\nLimit: "
+ floatBuffer.limit());
floatBuffer.flip();
System.out.println(
"\nBuffer after flip: "
+ Arrays.toString(
floatBuffer.array())
+ "\nPosition: "
+ floatBuffer.position()
+ "\nLimit: "
+ floatBuffer.limit());
}
}
|
Output:
Buffer before flip: [10.56, 20.34, 30.78]
Position: 1
Limit: 3
Buffer after flip: [10.56, 20.34, 30.78]
Position: 0
Limit: 1
Examples 2:
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
FloatBuffer floatBuffer
= FloatBuffer.allocate( 4 );
floatBuffer.put( 20 .4f);
floatBuffer.put( 34 .5f);
floatBuffer.position( 1 );
System.out.println(
"Buffer before flip: "
+ Arrays.toString(
floatBuffer.array())
+ "\nPosition: "
+ floatBuffer.position()
+ "\nLimit: "
+ floatBuffer.limit());
floatBuffer.flip();
System.out.println(
"\nBuffer after flip: "
+ Arrays.toString(
floatBuffer.array())
+ "\nPosition: "
+ floatBuffer.position()
+ "\nLimit: "
+ floatBuffer.limit());
}
}

Output:
Buffer before flip: [20.4, 34.5, 0.0, 0.0]
Position: 1
Limit: 4
Buffer after flip: [20.4, 34.5, 0.0, 0.0]
Position: 0
Limit: 1
