ShortBuffer rewind() method in Java with Examples
Last Updated :
28 Aug, 2019
The rewind() method of java.nio.ShortBuffer Class is used to rewind this buffer. By rewinding this Buffer, the following actions are taken:
- Current position is set to zero
- the mark is discarded, if any, but the mark value is unchanged.
Syntax:
public ShortBuffer rewind()
Parameter: This method do not accept any parameter.
Return Value: This method returns this buffer.
Below are the examples to illustrate the rewind() method:
Examples 1:
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
ShortBuffer shortBuffer
= ShortBuffer.allocate( 4 );
shortBuffer.put(( short ) 10 );
shortBuffer.put(( short ) 20 );
System.out.println(
"Buffer before operation: "
+ Arrays.toString(
shortBuffer.array())
+ "\nPosition: "
+ shortBuffer.position()
+ "\nLimit: "
+ shortBuffer.limit());
shortBuffer.rewind();
System.out.println(
"\nBuffer after operation: "
+ Arrays.toString(
shortBuffer.array())
+ "\nPosition: "
+ shortBuffer.position()
+ "\nLimit: "
+ shortBuffer.limit());
}
}
|
Output:
Buffer before operation: [10, 20, 0, 0]
Position: 2
Limit: 4
Buffer after operation: [10, 20, 0, 0]
Position: 0
Limit: 4
Examples 2:
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
ShortBuffer shortBuffer
= ShortBuffer.allocate( 5 );
shortBuffer.put(( short ) 10 );
shortBuffer.put(( short ) 20 );
shortBuffer.put(( short ) 30 );
shortBuffer.mark();
System.out.println(
"Buffer before operation: "
+ Arrays.toString(
shortBuffer.array())
+ "\nPosition: "
+ shortBuffer.position()
+ "\nLimit: "
+ shortBuffer.limit());
shortBuffer.rewind();
System.out.println(
"\nBuffer after operation: "
+ Arrays.toString(
shortBuffer.array())
+ "\nPosition: "
+ shortBuffer.position()
+ "\nLimit: "
+ shortBuffer.limit());
}
}

Output:
Buffer before operation: [10, 20, 30, 0, 0]
Position: 3
Limit: 5
Buffer after operation: [10, 20, 30, 0, 0]
Position: 0
Limit: 5
