Is there a way to store a variable in Java without losing it even after stopping the program without using files or databases ?

Answer 1

Well if your exit code counts, then you can pass an exit code to the calling process which can forward it to the next. But what'd be the use case?

Answer 2

If you end your program, the memory it's using gets deallocated. So for that purpose, no.
You could just store them in a file with encryption to stop users tampering, eg:
scores.dat
random data
#1 random data
#2 random data
random data #3 #4 random data
#5 random data

...then encrypt it. I assume tampering is the reason.

Answer 3

i will try to do it with files
thanks Jamie

Answer 4

I want to store variables in my program as a scores of players and keep them stored and refer to it later and display there values

Answer 5

You can serialize classes and deserialize them later. That would be a more advanced topic though...
