UppercaseCharacterRule
checks whether password contains specified number of upper case characters or
not.
UppercaseCharacterRule
provides below constructors.
UppercaseCharacterRule()
Default
constructor.
UppercaseCharacterRule(int
num)
Create
a new uppercase character rule. Parameter "num" specifies number of
uppercase characters to enforce.

Output
