This might be because the Pair class doesn’t specify the relationship between the specified values. It is clear from the above example that adding one element to a Pair will create a new Triplet. Subclass implementations may be mutable or immutable. Run keytool to generate a new key pair in the default development keystore file, keystore.jks.This example uses the alias server-alias to generate a new public/private key pair and wrap the public key into a self-signed certificate inside keystore.jks.The key pair is generated by using an algorithm of type RSA, with a default password of changeit. Let’s start by creating an object. This class is an abstract implementation defining the basic API. In this post, we will see how to implement our own Pair Class in Java.
