Storing integers in a compiled program

Question

I would am wriitng a program and I would like to generate a unique number for each time a users uses the compiled program, is it possible to store previously incremented numbers i.e. the last person who used this program got a print out number of 5. The next person to use this program would then get the number 6 etc etc? At the moment I have only been made familiar to coding in Java in a sort of runtime environment only.
An example of my thinking could be like so:
private int mynumber=1;
I woould then like to be able to set a new number most probably by creating a set method like so:
public int setMyNumber(int mynumber){
mynewnumber = mynumber+1;
return mynewnumber;
...... then in my main method I would like to return this new number. Please note this may not actually work but just giving you an idea of my thinking.
