I'm assuming hardware.
Remember, Hard = Physical.
If that's not it, try peripherals.
Answer:
<u>720</u> possible PIN can be generated.
Explanation:
To calculate different number of orders of digits to create password and PIN, we calculate permutation.
Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:
nPr = n!/(n-r)!
there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)
So in question we need to calculate
P=?
where
n= 10 (0-9 means total 10 digits)
r= 3 (PIN Consist of three digits)
So by using formula
10P3 = 10!/(10-3)!
=10!/7!
= 10x9x8x7!/7!
= 10x9x8
= 720
Answer:
All are True
Explanation:
a. A constructor must have the same name as that of a class. For example
public class MyFirstClass{ // this is the class name
public MyFirstClass() } // the constructor having the same name as class.
b. Constructors never have a return type not even void because it is only used to initialize the values of data members of the class when the object of the class is created so constructors are not directly called hence they do not need to have a return type.
c. Constructors are invoked using the new operator.
When the new object is created the constructor is invoked in order to initialize the variables of a class. The memory is allocated to the object and then the constructive is invoked for the purpose to initialize the object.
