Question

Errors can be syntax errors or logic errors (the code works, but not as intended).

Which of the following statements does NOT contain an error?
I) Scanner in = new Scanner(System.in);
II) System.out.print(Please enter your name (first last): );
III) String firstName = in.next();
Question 1Select one:
a. I only
b. II only
c. III only
d. I and II only
e. I and III only

Answer 1

In the code statements given, statements I (Scanner object creation) and III (reading the first name) are correct, while statement II contains a syntax error because quotes are missing from the string. Hence, the answer is 'I and III only'.

Step-by-step explanation:

The question presented is related to identifying which code statements do not contain errors. After evaluating each statement given:

1. Scanner in = new Scanner(System.in); - This is a correct Java syntax for creating a Scanner object which is used to read input from the standard input stream (typically a keyboard).
2. System.out.print(Please enter your name (first last): ); - This statement contains a syntax error because the string Please enter your name (first last): is not enclosed in quotes.
3. String firstName = in.next(); - This is a correct Java syntax assuming that a Scanner object in has been previously defined. It uses the .next() method to read the next token from the input, typically the first word or string until a space is encountered.

Therefore, the statements that do not contain an error are I and III. The correct answer is e. I and III only.
