Question

What is an argument? For the code below, give an example. What does the program do?

class Fact {
boolean isFact(int a, int b) {
if( (b % a) == 0) return true;
else return false;
}
}
class IsFact {
public static void main(String args[]) {
Fact x = new Fact();

if(x.isFact(2, 20)) System.out.println(""Yes it is"");
if(x.isFact(3, 20)) System.out.println(""this won't be displayed"");

}
}"

a) An argument is a value passed to a method when it is called. Example: x.isFact(2, 20).
b) An argument is a method's return value. Example: x.isFact(2, 20) returns "Yes it is."
c) An argument is a data type in Java. Example: int argument = 2.
d) The program calculates factorial values. Example: x.isFact(2, 20) calculates the factorial of 20.

Answer 1

An argument in programming is a value passed to a method; in the given Java code, the program checks if one number is divisible by another, displaying output accordingly.

Step-by-step explanation:

An argument in the context of computer programming refers to a value that is passed to a method when the method is called. For instance, in the Java code example provided, x.isFact(2, 20) is a method call with 2 and 20 as arguments. This aligns with option (a): An argument is a value passed to a method when it is called. The purpose of the isFact method in the Fact class is to determine whether the second argument is divisible by the first without any remainder, returning true if it is and false otherwise. The program's output will display "Yes it is" because 20 is divisible by 2, but nothing will be displayed for the x.isFact(3, 20) call since 20 is not divisible by 3.
