Thread: 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

package passing;
 
public class PassingMethods {
 
	static int passed1;
	static int passed2;
	static int passed3;
 
	public static void main(String[] args) {
 
		int passing = 10;
		// printing passing value and the new value
 
		System.out.println(passing);
		passing1(passing);
 
		System.out.println("\n" + passed1);
		passing2(passed1);
 
		System.out.println("\n" + passed2);
		passing3(passed2);
 
	}
 
	// Receiving value from main, and then passing new value
	public static void passing1(int passing) {
 
		int passed1 = passing + 2;
		System.out.println(passed1);
 
		PassingMethods.passed1 = passed1;
	}
 
	// Receiving new value from 1, and then passing new value
	public static void passing2(int passed1) {
 
		int passed2 = passed1 + 2;
		System.out.println(passed2);
 
		PassingMethods.passed2 = passed2;
 
	}
 
	// Receiving new value from 2, and then passing new value
	public static void passing3(int passed2) {
 
		int passed3 = passed2 + 2;
		System.out.println(passed3);
 
		PassingMethods.passed3 = passed3;
 
	}
 
}// end of class

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.
