以下是说明 getName() 方法的示例:
例 1:
// Java program to demonstrate
// get() method
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv) throws Exception
{
try {
// creating the object of KeyPairGenerator
KeyPairGenerator sr = KeyPairGenerator.getInstance("DSA", "SUN");
// getting the Provider of the KeyPairGenerator sr
// by using method getProvider()
Provider provider = sr.getProvider();
// getting the name of the provider using getName()
String name = provider.getName();
// printing the string info
System.out.println("name : " + name);
}
catch (NoSuchAlgorithmException e) {
System.out.println("Exception thrown : " + e);
}
}
}
Output:
name : SUN
例 2:
// Java program to demonstrate
// get() method
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv) throws Exception
{
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();
// getting the name of the provider using getName()
String name = provider.getName();
// printing the string info
System.out.println("name : " + name);
