El método aliases () es un método integrado de java.nio.charset que devuelve un conjunto que contiene los alias de este conjunto de caracteres. Cuando un objeto puede ser referido por varias referencias, lo que significa que almacenan el valor de referencia del mismo objeto, dichas referencias se denominan alias.
Sintaxis :
public final Set aliases()
Parámetros : La función no acepta ningún parámetro.
Valor de retorno : la función devuelve un conjunto que contiene strings que representan los alias incorporados de charset.
A continuación se muestra la implementación de la función anterior:
Programa 1:
// Java program to demonstrate
// the above function
import java.nio.charset.Charset;
import java.util.Iterator;
import java.util.Map;
public class GFG {
public static void main(String[] args)
{
// Create a Map which
// stores all available charsets
Map<String, Charset> charsets
= Charset.availableCharsets();
// Declare an iterator
Iterator<Charset> iterator
= charsets.values().iterator();
// Iterate till we have aliases
while (iterator.hasNext()) {
// Get the next iterator
Charset all = (Charset)iterator.next();
// Print the aliases
System.out.println(all.aliases());
System.out.println();
}
}
}
