El método de valores() de la clase java.security.Provider se utiliza para devolver una vista de colección no modificable de los valores de propiedad contenidos en este proveedor.
Sintaxis:
public Collection<Object> values()
Valor devuelto: este método devuelve una vista de colección de los valores contenidos en este mapa.
A continuación se muestran los ejemplos para ilustrar el método de valores() :
Ejemplo 1:
Java
// Java program to demonstrate
// values() method
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
// Declaring int value i
int i = 10;
try {
// creating the object of Signature
Signature sr = Signature.getInstance("SHA1withDSA");
// getting the Provider of the Signature sr
// by using method getProvider()
Provider provider = sr.getProvider();
// Declaring the variable of set<Map> type
Collection<Object> value;
// getting unmodifiable Set view of the property value
value = provider.values();
// Creating the object of iterator to iterate set
Iterator iter = value.iterator();
// printing the set elements
System.out.println("unmodifiable Set view : \n ");
while (i > 0) {
System.out.println("Value is : " + iter.next());
i--;
}
}
catch (NoSuchAlgorithmException e) {
System.out.println("Exception thrown : " + e);
}
}
}
Producción:
unmodifiable Set view : Value is : SHA1withDSA Value is : SHA1withDSA Value is : SHA1withDSA Value is : Software Value is : sun.security.provider.JavaKeyStore$DualFormatJKS Value is : SHA Value is : sun.security.provider.SHA Value is : sun.security.provider.JavaKeyStore$CaseExactJKS Value is : Software Value is : sun.security.provider.DSA$SHA256withDSA
Ejemplo 2:

// values() method
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
// Declaring int value i
int i = 10;
try {
// creating the object of SecureRandom
SecureRandom sr = SecureRandom.getInstance("SHA1PRNG");
// getting the Provider of the SecureRandom sr
// by using method getProvider()
Provider provider = sr.getProvider();
// Declaring the variable of set<Map> type
Collection<Object> value;
// getting unmodifiable Set view of the property value
value = provider.values();
// Creating the object of iterator to iterate set
Iterator iter = value.iterator();
// printing the set elements
System.out.println("unmodifiable Set view : \n ");
while (i > 0) {
System.out.println("Value is : " + iter.next());
i--;
}
}
catch (NoSuchAlgorithmException e) {
System.out.println("Exception thrown : " + e);
}
}
}
