help needed with inheritance

I have a class called Car and a main class that implements this class. Both are pasted below.

I expect the implementation to print out the price of the car but it is giving me price '0'.

Can anyone please advise as to what I am doing wrong.

Would be extremely thankful.

Check the spelling of the parameters of your car constructor.

Hi Ricky James
I know why result is 0 because in constructor

public Car(int regularPice, int speed, String colour) {
this.regularPrice = regularPrice;
this.colour = colour;
this.speed = speed;
this.regularPrice = regularPrice;
You assign this.regularPrice = regularPrice(value of this not value of parameter)
parameter is name regularPice.
I think regularPice not equal regularPrice and you miss 'r' in name of parameter.
You can tool so that create constructor and getter/setter.

It was really a good example to be very careful while going through others code (rather debugging) so that we can find out the silly mistakes like Spelling mistakes which actually causes the bug!!

Thanks for the Posting Ricky James and all others who helped Ricky find out the issue!!
