I am still learning but something weird happened.

In a new Workspace

Do-it myVar := LargeInteger new

Print-it myVar <error in printString: try 'Inspect it' to debug>

When I inspect it I get

SubclassResponsibility: LargeInteger had the subclass responsibility to implement #printOn:base:

When I browse LargeInteger, then at Integer level I get a message ��new�� as follows:

new

self == Integer ifTrue: [

^ self error: 'Integer is an abstract class. Make a concrete subclass.'].

^ super new

I looked for new higher up in the hierarchy(super), but could not see it. Maybe I am a bit dumb still with looking up.

I tried on SmallInteger a new, but got back

Error: SmallIntegers can only be created by performing arithmetic.

I then checked and noticed that SmallInteger actually have new and basicNew implemented (override)

So the error I got on smallinteger was from the override

LargeInteger has no override, but has a ��silent" error

This seems a bit weird to me

Just so you know I also tried

Do-it myVar := LargeInteger new: 10000

Print-it myVar class. -> LargeInteger

Dot-it myVar := myVar + 1

The last statement hangs the image! (Tried 3 times)

Comment:

1. I am surprised that Do-it did not give me an error on the new: (there is a message is the hierarchy of new:neg and maybe the neg is optional?)

2. The new: seemed to have created 10000 LargeIntegers

3. I tried the new: also with just 5, and same result, image hang. (I thought 10,000 was maybe a very large loop for the + 1..)

Did I damage something in the image maybe? I started this one just yesterday to look at MOOC week1.

I do not need LargeIntegers for now but ��
