KeyStore getType() method in Java with Examples
Last Updated :
10 Dec, 2019
The getType() method of java.security.KeyStore class is used to get the type of this keystore.
Syntax:
public final String getType()
Parameter: This method accepts nothing as a parameter.
Return Value: This method returns the type of this keystore.
Note: All the programs in this article won’t run on online IDE as no ‘privatekey’ Keystore exists. You can check this code on Java compiler on your system. To check this code, create a Keystore ‘privatekey’ on your system and set your own Keystore password to access that Keystore.
Below are the examples to illustrate the getType?() method:
Example 1:
import java.security.*;
import java.security.cert.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
try {
KeyStore sr = KeyStore.getInstance( "JKS" );
char [] pass = ( "123456" ).toCharArray();
InputStream is
= new FileInputStream(
"f:/java/private key.store" );
sr.load(is, pass);
String type = sr.getType();
System.out.println( "Type of keystore : "
+ type);
}
catch (NoSuchAlgorithmException e) {
System.out.println( "Exception thrown : " + e);
}
catch (NullPointerException e) {
System.out.println( "Exception thrown : " + e);
}
catch (KeyStoreException e) {
System.out.println( "Exception thrown : " + e);
}
catch (FileNotFoundException e) {
System.out.println( "Exception thrown : " + e);
}
catch (IOException e) {
System.out.println( "Exception thrown : " + e);
}
catch (CertificateException e) {
System.out.println( "Exception thrown : " + e);
}
}
}

Example 2: For Without loading keystore
import java.security.*;
import java.security.cert.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
try {
KeyStore sr = KeyStore.getInstance( "JKS" );
char [] pass = ( "123456" ).toCharArray();
InputStream is
= new FileInputStream(
"f:/java/private key.store" );
String type = sr.getType();
System.out.println( "Type of keystore : "
+ type);
}
catch (NullPointerException e) {
System.out.println( "Exception thrown : " + e);
}
catch (KeyStoreException e) {
System.out.println( "Exception thrown : " + e);
}
catch (FileNotFoundException e) {
System.out.println( "Exception thrown : " + e);
}
}
