Question

Which of the following represents a method call to a method with a void return type?

a) greeting.toUpperCase()
b) System.out.println()
c) greeting.replace("Hello","World")
d) ()

Answer 1

System.out.println() is the method call with a void return type, as it prints to the console without returning any value.

Step-by-step explanation:

The question posits a scenario where a student is asked to identify which of the provided options is an example of a method call with a void return type. In programming, particularly in the context of Java, a method with a void return type is a method that does not return any value. Looking at the provided options, the one that matches this characteristic is:

• System.out.println()

This method call prints the specified message to the console and does not return any value, which is indicative of a void return type. On the other hand, the other options, greeting.toUpperCase() and greeting.replace("Hello","World"), return a String and therefore do not have a void return type.
