Question

Distinguish between (p != q) and !(p == q).

Answer 1

S. No.	(p != q)	!(p == q)
1.	This condition will be true if p and q are not equal.	Even if p and q are equal, false is returned because of the (NOT !) operator.
2.	Example:  p = 20; q = 21; boolean r = (p != q ) // r = true	Example:  p = 20; q = 20; boolean r = (p == q ) // r = false
