Answer 1

Answer:

1. (i) & (iii)

This is the correct answer.

Explanation:

There are mainly two types of comments in Java:

1. Single Line Comment: Single line comments starts with two forward slashes (//). Any text in front of // is not executed by Java.

Example: public static void main( ){  //This is a single line comment
