Class LCOM1

LCOM1 (Chidamber & Kemerer, 1991)

Formula: LCOM1 = |P| - |Q|, where P > Q, otherwise 0

Where:

• P is the set of method pairs that do not share instance variables
• Q is the set of method pairs that share at least one instance variable
• If P <= Q, then LCOM1 = 0

Returns a value >= 0:

• 0: good cohesion
• Higher values: lack of cohesion
