Question

If greeting is a String object, which method call is incorrect?

a) greeting.toLowerCase()
b) greeting.toUpperCase()
c) greeting.println()
d) ()

Answer 1

The incorrect method call is greeting.println().

Step-by-step explanation:

The incorrect method call in this scenario is c) greeting.println().

The toLowerCase() method converts all characters in a string to lowercase, while the toUpperCase() method converts all characters to uppercase. These methods are commonly used for text manipulation and formatting.

On the other hand, greeting.println() is not a valid method call for a String object. The method println() is used to print a line of text to the console, but it is not a method available for String objects.
