How to keep a variable value even after doing run as-> Java Application?

I know that when we use static variables the value remains the same for all the instances of a class.

But when I do run as -> Java Application in a class, even the static variable is reinicialized with the default value.

Is there any way to keep a variable value even after doing run as-> Java Application in a class?

Thank you.

Save to a file, and read it when you want it again from FILE, I know that’s not a good programming standard, if it’s related to login credentials.

Static variables works only for runtime execution, so they won’t help and can store variables even after program terminates.
