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
In Java programming, the <u>%s</u> format specifier can receive any type of Java data.
<h3>The kinds of data type.</h3>
In Computer programming, there are five recognized data types and these include:
- Floating point type (float).
<h3>What is a string?</h3>
A string is a data type which is typically used for data values that comprises ordered sequences of characters.
In Java programming, strings can be used to represent all Java data types such as numbers, Boolean, strings, etc. Also, the <u>%s</u> format specifier can be used by a programmer or software developer to receive any type of Java data.
