java.security.Provider.Service類的getType()方法提供提供程序服務的類型。
用法:
public final String getType()
返回值:此方法提供特定類型的提供程序服務。
下麵是說明getType()方法的示例:
範例1:
// Java program to demonstrate
// getType() 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 type of Provider.Service object
// by using getClassName() method
String name = service.getType();
// display the result
System.out.println("Name of the type:"
+ name);
}
catch (NoSuchAlgorithmException e) {
System.out.println("Exception thrown:" + e);
}
catch (NoSuchProviderException e) {
System.out.println("Exception thrown:" + e);
}
}
}
輸出:
Name of the type:Signature
範例2:
// Java program to demonstrate
// getType() method
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
// creating object of MessageDigest
MessageDigest msd
= MessageDigest.getInstance("MD5");
// getting the Provider of the Signature sr
// by using method getProvider()
Provider provider = msd.getProvider();
// getting the service of the provider
// using getServices() method
Provider.Service service
= provider
.getService("MessageDigest",
msd.getAlgorithm());
// getting type of Provider.Service object
// by using getClassName() method
String name = service.getType();
// display the result
System.out.println("Name of the type:"
+ name);
}
catch (NoSuchAlgorithmException e) {
System.out.println("Exception thrown:" + e);
}
}
}
輸出:
Name of the type:MessageDigest
