The getType() method of java.security.Provider.Service class provides the type of the provider service. 

Syntax:

public final String getType()

Return Value: This method provides specific type of provider service. 

Below are the examples to illustrate the getType() method: 

Example 1: 

Java




// 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 getType() 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);
        }
    }
}


Output:

Name of the type : Signature

Example 2: 

Java




// 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 getType() 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);
        }
    }
}


Output:

Name of the type : MessageDigest
