Question

In a class definition with $10$ methods, to make the class maximally cohesive, number of direct and indirect connections required among the methods are

• A. $90,0$
• B. $45,0$
• C. $10,10$
• D. $45,45$

Answer 1

To make the class maximally cohesive, every method should be related to every other method.

It is like a complete graph of 10 vertices. i.e.,

n(n-1)/2

10(9)/2=45,  and all these were direct connections

hence option b is the answer

Comments

In indirect connections, there won't be a node connected to any other node, so there is no relation b/w two modules.

Is that why there can't be Indirect cohesive classes?

no, I am thinking it as a complete graph with n nodes, in the complete graph there won't be any indirect connections, every node is connected directly with one another

Okay understood. Thanks

I think in your meaning of indirect was A→b→c so a to c is indirect connection, but every node is connected to each other than there is no indirect.
