putShort(int value)
The putShort(int value) method of java.nio.ByteBuffer Class is used to write two bytes containing the given short value, in the current byte order, into this buffer at the current position, and then increments the position by two.
Syntax:
public abstract ByteBuffer putShort(short value)
Parameters: This method takes the short value to be written.
Return Value: This method returns this buffer.
Exception: This method throws the following exceptions:
- BufferOverflowException- If this buffer’s current position is not smaller than its limit
- ReadOnlyBufferException- If this buffer is read-only
Below are the examples to illustrate the putShort(short value) method:
Example 1:
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 6 ;
try {
ByteBuffer bb = ByteBuffer.allocate(capacity);
bb.putShort(( short ) 0x041A )
.putShort(( short ) 0x042A )
.putShort(( short ) 0x043A )
.rewind();
System.out.print("Original ByteBuffer: [ ");
for ( int i = 1 ; i <= capacity / 2 ; i++)
System.out.print(bb.getShort() + " ");
System.out.print("]");
}
catch (BufferOverflowException e) {
System.out.println("Exception throws : " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws : " + e);
}
}
}
|
Output:
Original ByteBuffer: [ 1050 1066 1082 ]
Example 2: To demonstrate BufferOverflowException.
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 6 ;
try {
ByteBuffer bb = ByteBuffer.allocate(capacity);
bb.putShort(( short ) 0x041A )
.putShort(( short ) 0x042A )
.putShort(( short ) 0x043A )
.rewind();
System.out.print("Original ByteBuffer: [ ");
for ( int i = 1 ; i <= capacity / 2 ; i++)
System.out.print(bb.getShort() + " ");
System.out.print("]");
bb.putShort(( short ) 234 );
}
catch (BufferOverflowException e) {
System.out.println("\n\nbuffer's current position"
+ " is not smaller than its limit");
System.out.println("Exception throws : " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws : " + e);
}
}
}
|
Output:
Original ByteBuffer: [ 1050 1066 1082 ]
buffer's current position is not smaller than its limit
Exception throws : java.nio.BufferOverflowException
Examples 3: To demonstrate ReadOnlyBufferException.
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 6 ;
try {
ByteBuffer bb = ByteBuffer.allocate(capacity);
bb.putShort(( short ) 0x041A )
.putShort(( short ) 0x042A )
.putShort(( short ) 0x043A )
.rewind();
System.out.print("Original ByteBuffer: [ ");
for ( int i = 1 ; i <= capacity / 2 ; i++)
System.out.print(bb.getShort() + " ");
System.out.print("]");
ByteBuffer bb1 = bb.asReadOnlyBuffer();
System.out.println("\n\nTrying to put the short value"
+ " in read-only buffer");
bb1.putShort(( short ) 234 );
}
catch (BufferOverflowException e) {
System.out.println("\n\nbuffer's current position"
+ " is not smaller than its limit");
System.out.println("Exception throws : " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws : " + e);
}
}
}

Output:
Original ByteBuffer: [ 1050 1066 1082 ]
Trying to put the short value in read only buffer
Exception throws : java.nio.ReadOnlyBufferException
putShort(int index, short value)
The putShort(int index, short value) method of java.nio.ByteBuffer Class is used to write two bytes containing the given two value, in the current byte order, into this buffer at the given index.
Syntax:
public abstract ByteBuffer putShort(int index, short value)
Parameters: This method takes the following arguments as a parameter:
- index: The index at which the byte will be written
- value: The short value to be written
Return Value: This method returns this buffer.
Exception: This method throws the following exception:
- IndexOutOfBoundsException- If index is negative or not smaller than the buffer’s limit
- ReadOnlyBufferException- If this buffer is read-only
Below are the examples to illustrate the putShort(int index, short value) method:
Example 1:
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 6 ;
try {
ByteBuffer bb = ByteBuffer.allocate(capacity);
bb.putShort( 0 , ( short ) 23 );
bb.putShort( 2 , ( short ) 34 );
bb.putShort( 4 , ( short ) 27 );
bb.rewind();
System.out.print("Original ByteBuffer: [ ");
for ( int i = 1 ; i <= capacity / 2 ; i++)
System.out.print(bb.getShort() + " ");
System.out.print("]\n");
}
catch (IndexOutOfBoundsException e) {
System.out.println("Exception throws : " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws : " + e);
}
}
}

Output:
Original ByteBuffer: [ 23 34 27 ]
Example 2: To demonstrate IndexOutOfBoundsException.
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 6 ;
try {
ByteBuffer bb = ByteBuffer.allocate(capacity);
bb.putShort( 0 , ( short ) 23 );
bb.putShort( 2 , ( short ) 34 );
bb.putShort( 4 , ( short ) 27 );
bb.rewind();
System.out.print("Original ByteBuffer: [ ");
for ( int i = 1 ; i <= capacity / 2 ; i++)
System.out.print(bb.getShort() + " ");
System.out.print("]\n");
bb.putShort(- 1 , ( short ) 45 );
}
catch (IndexOutOfBoundsException e) {
System.out.println("\nindex is negative or not smaller "
+ "than the buffer's limit");
System.out.println("Exception throws : " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws : " + e);
}
}
}

Output:
Original ByteBuffer: [ 23 34 27 ]
index is negative or not smaller than the buffer's limit
Exception throws : java.lang.IndexOutOfBoundsException
Example 3: To demonstrate ReadOnlyBufferException.
Java
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 6 ;
try {
ByteBuffer bb = ByteBuffer.allocate(capacity);
ByteBuffer bb1 = bb.asReadOnlyBuffer();
System.out.println("Trying to put the int value"
+ " in read-only buffer");
bb1.putInt( 0 , 23 );
}
catch (IndexOutOfBoundsException e) {
System.out.println("Exception throws : " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws : " + e);
}
}
