Question

question 6
which of the following should be defined as a void method?
a write a method that converts an uppercase letter to lowercase.
b write a method that prints integers from 1 to 100.
c write a method that checks whether a number is from 1 to 100..
d write a method that returns a random integer from 1 to 100.

Explanation:

A void method is one that does not return a value.

• Option A: Converting a letter and returning the lowercase version would require a return type (e.g., char), so it's not void.
• Option B: Printing integers (e.g., using System.out.println in Java) does not need to return a value. This is a typical use case for a void method.
• Option C: Checking a condition would likely return a boolean (e.g., true if the number is in the range, false otherwise), so it's not void.
• Option D: Returning a random integer would have a return type (e.g., int), so it's not void.

Answer:

B. Write a method that prints integers from 1 to 100.
