• If the range condition is given as an input, then one valid and two invalid equivalence classes are defined. 
• If a specific value is given as input, then one valid and two invalid equivalence classes are defined. 
• If a member of set is given as an input, then one valid and one invalid equivalence class is defined. 
• If Boolean no. is given as an input condition, then one valid and one invalid equivalence class is defined.
