El método compareTo() de la clase java.nio.ShortBuffer se utiliza para comparar un búfer con otro.
Dos búferes cortos se comparan comparando sus secuencias de elementos restantes lexicográficamente, sin tener en cuenta la posición inicial de cada secuencia dentro de su búfer correspondiente. Los pares de elementos cortos se comparan como si se invocara Short.compare(short, short). Un búfer corto no es comparable a ningún otro tipo de objeto.
Sintaxis :
public int compareTo(ShortBuffer that)
Parámetro : este método toma un objeto shortbuffer como parámetro con el que se comparará este búfer.
Valor de retorno : este método devuelve un número entero negativo, cero o un número entero positivo , ya que este búfer es menor, igual o mayor que el búfer dado.
A continuación se muestran los ejemplos para ilustrar el método compareTo() :
Programa 1 : Cuando ambos FloatBuffer son iguales.
