Thread: help with creating a method and returning a value

Hi. I am having trouble understanding some simple concepts. I am frustrated.

I typed this simple code and it counts up by three's.



import acm.program.*;

public class Freespace extends ConsoleProgram {

private static final int MAX_COUNT = 300;


public void run() {

println("Count upwards by 3's");
for (int i = 0; i <= MAX_COUNT; i = i + 3) {
println(i);
}
}
}

I want to create a private method that does the counting for me and then returns it to the public method, but I am stuck.

I basically want the method to be called countThree and have the calculations and for loop done there. Please help. My textbook is vague on its example and Google results are always in a different library I dont know the syntax of yet.

The ACM packages are part of The Art and Science of Java textbook... the source of my learning.

Basically, I am learning information hiding and would like the main public class to receive the code that counts by three from the new Private method I create.

It is hard for me to elaborate.

--- Update ---

import acm.program.*;

public class Freespace extends ConsoleProgram {

private static final int MAX_COUNT = 300;


public void run() {

println("Count upwards by 3's");

// now I want to get a return result from the new method countThree below




private int countThree() {

for (int i = 0; i <= MAX_COUNT; i = i + 3) {
println(i);
}

//how can I get this result returned to the public void


}
}

The countThree() method doesn't have anything to return that I can see. It is designed to count (print) and that's all.
