<DL>
<DD>Loads this KeyStore from the given input stream.

 <p>If a password is given, it is used to check the integrity of the
 keystore data. Otherwise, the integrity of the keystore is not checked.

 <p>In order to create an empty keystore, or if the keystore cannot
 be initialized from a stream (e.g., because it is stored on a hardware
 token device), you pass <code>null</code>
 as the <code>stream</code> argument.

 <p> Note that if this KeyStore has already been loaded, it is
 reinitialized and loaded again from the given input stream.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>stream</CODE> - the input stream from which the keystore is loaded, or
 null if an empty keystore is to be created.<DD><CODE>password</CODE> - the (optional) password used to check the integrity of
 the keystore.<DT><B>Throws:</B><DD><CODE><A HREF="../../java/io/IOException.html">IOException</A></CODE> - if there is an I/O or format problem with the

getDefaultType</H3>
<PRE>
public static final <A HREF="../../java/lang/String.html">String</A> <B>getDefaultType</B>()</PRE>
<DL>
<DD>Returns the default keystore type as specified in the Java security
 properties file, or the string &quot;jks&quot; (acronym for &quot;Java keystore&quot;)
 if no such property exists.
 The Java security properties file is located in the file named
 &lt;JAVA_HOME&gt;/lib/security/java.security, where &lt;JAVA_HOME&gt;
 refers to the directory where the SDK was installed.

 <p>The default keystore type can be used by applications that do not
 want to use a hard-coded keystore type when calling one of the
 <code>getInstance</code> methods, and want to provide a default keystore
 type in case a user does not specify its own.

 <p>The default keystore type can be changed by setting the value of the
 "keystore.type" security property (in the Java security properties
 file) to the desired keystore type.<DD><DL>
<DT><B>Returns:</B><DD>the default keystore type as specified in the
