How can I perform a strict host key checking using JSch - ssh

Question

I am trying to connect to a server using JGit. I can connect successfully using the following setting
JSch.setConfig("StrictHostKeyChecking", "no");
The problem is that I actually want a strict host key checking. So I replaced the previous line with the following:
JSch.setConfig("StrictHostKeyChecking", "yes");
But now it doesn't work. My certificates a located in a folder called .ssh located in my home directory. The names of the files are id_rsa and id_rsa.pub. In the server (that has Linux) I have a file called authorized_keys located in ~/.ssh which has the same content as id_rsa.pub.

The code was actually ok. The problem is that you have to do the following things:
These operation must be performed on you client computer.
1) Create a folder named .ssh in you home directory (for example C:\Users\John)
2) Enter the new folder and create the certificates using git bash with the following command
ssh-keygen -t rsa -m PEM
The certificates are 2 files named id_rsa and id_rsa.pub
3) Type the following command (always using git bash):
ssh-keyscan -t rsa ip_address_of_your_server >> ~/.ssh/known_hosts
It will create a file called known_hosts. So eventually in the .ssh folder of the client there will be 3 files: id_rsa, id_rsa.pub and known_hosts.
Now go to you server computer and do the following
1) Create a folder named .ssh in you home directory (for example ~/John)
2) Enter there and create a file named authorized_keys and copy the content of the file id_rsa.pub inside this new file
3) Find the file etc/ssh/sshd_config
4) Make sure that the following 2 lines are present and uncommented
PubKeyAuthentication yes
PasswordAuthentication no
5) Save the file and restart sshd
sudo systemctl restart sshd
