    Default Where should I toggle the breakpoints ?

    I'd like to understand how this program runs but I dont know where to toggle the breakpoints .

    abstract class A
    {
        abstract void firstMethod();
     
        void secondMethod()
        {
            System.out.println("SECOND");
     
            firstMethod();
        }
    }
     
    abstract class B extends A
    {
        @Override
        void firstMethod()
        {
            System.out.println("FIRST");
     
            thirdMethod();
        }
     
        abstract void thirdMethod();
    }
     
    class C extends B
    {
        @Override
        void thirdMethod()
        {
            System.out.println("THIRD");
        }
    }
     
    public class MainClass1
    {
        public static void main(String[] args)
        {
            C c = new C();
     
            c.firstMethod();
     
            c.secondMethod();
     
            c.thirdMethod();
        }
    }

    Put just one breakpoint on "c.firstMethod();" near the bottom and then use Step Into exclusively. Each statement it stops at is another place where you could put a breakpoint if you wanted.
