Question

Complete the code by filling in the blanks with the appropriate conditions.

a) phone.length(), phone.length()
b) phone.size(), phone.size()
c) phone.size(), phone.length()
d) phone.length(), phone.size()

Answer 1

Without context, it's unclear whether 'phone.length()', 'phone.size()', or a combination should be used, as 'length()' typically refers to strings and arrays, while 'size()' refers to collections in Java.

Step-by-step explanation:

The proper conditions to complete the code depend on the context in which the variable 'phone' is used. If 'phone' is a string in languages like Java or Python, we would use phone.length() to get the number of characters in the string, which suggests that the applicable option would be 'a) phone.length(), phone.length()'.

On the other hand, if 'phone' is a type of collection, such as an array or ArrayList in Java, phone.size() would be used to get the number of elements in it. Without a specific context, it isn't possible to definitively determine the correct answer. However, it is important to note that length() is typically associated with strings and arrays, while size() is associated with collections in Java.
