Let's end our example by creating a fully self-contained executable jar file that can run in a production environment. Executable jars (sometimes become fat jars "fat jars") is an archive that contains your compiled class and the dependent jar required for your code to run.Executable Jars and Java:Java does not provide any standard way to load inline jar files, which also contain jar files in jar files. This is a problem if you want to publish a self-

Item 1: Consider static factory methods instead of constructorsAdvantage:One advantage of static factory methods is, unlike constructors, they has names.A second advantage of static factory methods is, unlike constructors, they was not required to create a new objec T each time they ' re invoked.A third advantage of static factory methods is, unlike constructors, they can return an object of any subtype of Their return type.A fourth advantage of static factory methods is that they reduce the ver

Create a OpenSSL profile on the local computer by modifying the fields below for your own needs.Note 1: In the example used in this article, the configuration file is named "Req.conf".Note 2: "Req_extensions" will place the subject alternative name in the CSR, and "X509_extensions" will be used when creating the actual certificate file.
