Line 3 is a comment that documents what the program is and how it is constructed. Other keywords in this program are public, static, and void. For example, when the compiler sees the word class, it understands that the word after class is the name of the class. Keywords have a specific meaning to the compiler and cannot be used for other purposes in the program. Big application to development many module learing advance level of.
