Answer:
The program to this question can be given as follows:
Program:
public class data //defining class data
{
//main method
public static void main (String [] as) //declaring main method
{
int userNum = 4; //declare variable userNum and assign value
for (userNum = 1; userNum <= 4; userNum++) //loop for print values
{
System.out.println(userNum); //print values in new lines.
}
}
}
Output:
1
2
3
4
Explanation:
In the above java program code firstly a class "data" is defined, inside this class the main method is defined in which an integer variable userNum is defined that holds a value that is "4".
- In this method, a for loop is declare that uses variable userNum which starts from 1 and ends with a given value that is equal to 4.
- Inside a for loop, the print function is used that print userNum variable each values in the newline.
Write "i" the write random words then delete it and add the lowercase i
Answer:
a) It is used for authentication.
Explanation:
Hashing is a process of transforming a single key into another value. It generates the values using a mathematical algorithm. the outcome of this process is a hash value or a hash.
The hashing process is used for authentication.
The hashing process is not reversible.
The hashing process is used to create the digital signature.
The outcome of the hashing process is the hash value, not a message.
Answer:
C. sqrt(Math)
Explanation:
All but one of options A to E are is not a static method.
Only option C is a static method. The sqrt() is a static method of Math, that can always be used as Math.sqrt() is used;
The Math class defines all of its methods to be static. Invoking Math methods is done by using Math as a method rather than a variable of type Math; this means that sqrt(Math) doesn't rely on instance variables and don't need to be overridden, unlike others.
Lastly, sqrt(Math) is a static method because unlike other options, it is an utility method, and it is relevant to computations on primitive data types.
The purpose of the static method is in large part to offer a standard library of functions, and it doesn't need to be applied directly to an object.
Imagine cashing or taking money using the Automated Teller Machine (ATM) and the banking hall, the two ways are When it involves convenience, not anything can beat ATMs.
<h3>What are the benefits and drawbacks of the usage of an ATM card?</h3>
No credit score allowed: A debit card is related for your financial institution account. There isn't anyt any opportunity of creating any transaction on credit score. All transactions and withdrawals are restricted to the stability to be had for your account. Difficult to dispute fraudulent use: It is less difficult to fraudulently use your debit card.
Automated Teller Machine (ATM) – It is a digital system that is operated with the aid of using clients and lets in acting for monetary transactions consisting of switch funds, coins withdrawals, and deposits. It extensively utilized for acquiring account facts at any time and with out the assist of financial institution staff.
