Compile-time Binding and Run-time Binding (Static & Dynamic Binding)

Consider the following program:

class Parent
{
   public void demo(double d)
    {
        System.out.println("Parent "+d);
    }

   public void test(double d)
    {
        System.out.println("Parent Test "+d);
    }
}

class Child extends Parent
{
   public void demo(int d)
    {
        System.out.println("Child "+d);
    }
   public void test(double d)
    {
        System.out.println("Overriding test in Child "+d);
    }
}

class CompileTimeBinding
{
   public static void main(String...rk)
    {
        Parent p = new Child();
        p.demo(5);   //Compile time Binding
        p.test(5);   //Run-time Binding

       
      }
}
