putShort(valor int)
El método putShort(int value) de java.nio.ByteBuffer Class se usa para escribir dos bytes que contienen el valor corto dado, en el orden de bytes actual, en este búfer en la posición actual y luego incrementa la posición en dos.
Sintaxis:
public abstract ByteBuffer putShort(short value)
Parámetros: Este método toma el valor corto a escribir.
Valor devuelto: este método devuelve este búfer.
Excepción: este método arroja las siguientes excepciones:
- BufferOverflowException: si la posición actual de este búfer no es más pequeña que su límite
- ReadOnlyBufferException : si este búfer es de solo lectura
A continuación se muestran los ejemplos para ilustrar el método putShort (valor corto):
Ejemplo 1:
// Java program to demonstrate
// putShort() method
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// Declaring the capacity of the ByteBuffer
int capacity = 6;
// Creating the ByteBuffer
try {
// creating object of ByteBuffer
// and allocating size capacity
ByteBuffer bb = ByteBuffer.allocate(capacity);
// putting the value in ByteBuffer
// using putShort() method
bb.putShort((short)0x041A)
.putShort((short)0x042A)
.putShort((short)0x043A)
.rewind();
// print the ByteBuffer
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);
}
}
}

putShort(índice int, valor corto)
El método putShort(int index, short value) de java.nio.ByteBuffer Class se usa para escribir dos bytes que contienen los dos valores dados, en el orden de bytes actual, en este búfer en el índice dado.
Sintaxis:
public abstract ByteBuffer putShort(int index, short value)
Parámetros: Este método toma los siguientes argumentos como parámetro:
- index : el índice en el que se escribirá el byte
- value : El valor corto que se escribirá
Valor devuelto: este método devuelve este búfer.
Excepción: este método arroja la siguiente excepción:
- IndexOutOfBoundsException: si el índice es negativo o no más pequeño que el límite del búfer
- ReadOnlyBufferException : si este búfer es de solo lectura
A continuación se muestran los ejemplos para ilustrar el método putShort(int index, short value):
