    Default Can someone please help with code evaluation and improvement

    This code works, but I don't know if this is the best way to do this.
    I'm looking for help
    1) is it right
    2) is there a better way
    3) is there a more secure way

    Welcome to the forum, good first post, but it would be helpful to know:

    What is the program supposed to be doing, and what do you mean by "more secure?"

    what I 'm trying to do here learn variable passing from method to method
    it's taking from main passing it,

    to first method then adding to it and passing the results
    then method 2 is taking the results and adding to it and passing those results
    then method 3 is taking the results and adding to it and passing those results
    the main is just printing the changes to the screen so I can see it's working

    goes as 10 comes out as 12
    goes as 12 comes out as 14
    goes as 14 comes out as 16

    more secure is dealing private verse public

    And what are these statements supposed to be doing:

    PassingMethods.passed1 = passed1;

    The fact that your entire program is 'static' is making the demonstration you've described more difficult, next to impossible. From the main() method call a constructor that calls non-static methods using non-static variables. Return the results from the methods, and assign the results of the methods to variables or print them directly. That will be a much more useful demonstration of passing variables to and receiving/using the results of methods.
