Class LCOM2

LCOM2 (Chidamber & Kemerer, 1994 - revised)

Formula: LCOM2 = 1 - (Σ(MF) / (M * F))

Where:

• M is the number of methods in the class
• F is the number of fields in the class
• MF is the number of methods that access each field
• Σ(MF) is the sum of MF over all fields

Returns a value between 0 and 1:

• 0: perfect cohesion (all methods access all fields)
• 1: no cohesion (no method accesses any field)
