  A HTTPS client and HTTPS server demo in Java

In this post, I will create a HTTPS server and HTTPS client demo which can establish HTTPS communication between a server and a client using Java. This should be very useful when we want to test our understanding about SSL communication. We will use both a detailed SSL client and a simple HttpsURLConnection as the HTTPS client. Before creating the actual HTTPS server and HTTPS client, we first need to generate the keystore and truststore to be used by the server and client. To generate the keyst...

So many problems in software occur because programmers and designers don't communicate well all the time.

People's minds work in different ways, they can process thoughts differently, solve problems in completely different but equally valid ways. It's a mistake to assume everyone should possess the same skill set.  Also not everyone should be a full stack engineer although full stac...
