ShortBuffer clear() methods in Java with Examples
Last Updated :
26 Aug, 2019
The clear() method of java.nio.ShortBuffer Class is used to clear this buffer. While clearing this buffer following changes are done:
- the current position is set to zero
- the limit of this ShortBuffer instance is set to the capacity
- the mark, if any, of this ShortBuffer instance is discarded.
Syntax:
public final ShortBuffer clear()
Return Value: This method returns this ShortBuffer instance after clearing all the data from it.
Below are the examples to illustrate the clear() method:
Examples 1:
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
try {
short[] darr = { 2, 3, 4, 6 };
ShortBuffer db
= ShortBuffer.wrap(darr);
db.position(2);
db.mark();
db.position(4);
System.out.println("position before reset: "
+ db.position());
db.clear();
System.out.println("position after reset: "
+ db.position());
}
catch (InvalidMarkException e) {
System.out.println("new position is less than "
+ "the position we "
+ "marked before ");
System.out.println("Exception throws: " + e);
}
}
}
|
Output:
position before reset: 4
position after reset: 0
Examples 2:
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
short[] carr = { 2, 10, 13, 23 };
ShortBuffer db = ShortBuffer.wrap(carr);
db.position(3);
System.out.println("position before clear: "
+ db.position());
db.clear();
System.out.println("position after clear: "
+ db.position());
}
}
|
Output:
position before clear: 3
position after clear: 0
