Question

Which of the following starts a single line Java comment? Select one:

a. //
b. //*
c. */
d. ///
e. If you think none of the above starts a multi-line Java comment, select this option

Answer 1

The symbol for starting a single line comment in Java is //, which is used to add notes or to disable code execution on that line.

Step-by-step explanation:

To start a single line comment in Java, you use //. This indicates that the rest of the line is a comment and should not be executed as part of the program. It's essential for adding notes or temporarily disabling code.

The correct option that starts a single line Java comment is a. //. The double forward slash is used to indicate that everything after it on the same line is a comment and will be ignored by the compiler. This is often used to add explanatory or descriptive notes to the code.
