Calling a void method

Currently I have this code coded as a part of a separate Java class.

 public void setSubtotal () { subtotal = Validator.getDouble(sc,"Enter subtotal:", 0, 10000); } 

And I want to call to it from another method. I already have this class instantiated so I can call to it, but I'm not sure how to call to this method since it's a void method.

all you gotta do is

 this.setSubtotal(); 

since you're doing it inside the same class

public class Y{ public static void main(String args[]){ X foo = new X(); foo.setSubtotal(); } } public class X{ public void setSubtotal () { subtotal = Validator.getDouble(sc,"Enter subtotal:", 0, 10000); } }
