El método toString() de la clase java.security.Provider.Service devuelve una representación de string de este servicio de proveedor.
Sintaxis:
public String toString()
Valor devuelto: este método proporciona una representación de string de este servicio de proveedor.
A continuación se muestran los ejemplos para ilustrar el método toString() :
Ejemplo 1:
// Java program to demonstrate
// toString() method
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
// creating the object of Signature
Signature sr
= Signature.getInstance(
"SHA1withDSA",
"SUN");
// getting the Provider of the Signature sr
// by using method getProvider()
Provider provider = sr.getProvider();
// getting the service of the provider
// using getServices() method
Provider.Service service
= provider
.getService("Signature",
sr.getAlgorithm());
// getting string representation
// of Provider.Service object
// by using getClassName() method
String value = service.toString();
// display the result
System.out.println("String representation : "
+ value);
}
catch (NoSuchAlgorithmException e) {
System.out.println("Exception thrown : " + e);
}
catch (NoSuchProviderException e) {
System.out.println("Exception thrown : " + e);
}
}
}
Representación de strings: SUN: Signature.SHA1withDSA -> sun.security.provider.DSA$SHA1withDSA

{
try {
// creating object of MessageDigest
MessageDigest msd
= MessageDigest.getInstance("MD5");
// getting the Provider of the Signature sr
// by using method getProvider()
