Are Java keywords written in lowercase as well as uppercase?

The correct answer to this question is False. They are not written in both lowercase and uppercase. Instead, JavaScript is case sensitive. Due to this, all of the keywords must be written in a small case.

An example is with the word baby. It must be written as a baby and not Baby or BABY. Another example would be with the word and name McDonald. Though there are various ways to have this name with different capitalization, the correct way in JavaScript would be McDonald, and not MCDONALD or McDonald's.

Keywords are not the only things in JaVa that are case sensitive, but variables and function names are as well.

False
Java keywords are not written in lowercase as well as uppercase. JavaScript is known to be case sensitive. All the keywords are the small case in the original java version. Therefore, Java keywords must be written with a consistent capitalization of the letters. For example, the word apple must be typed as "an apple," not "Apple" or "APPLE."

Another example of this is the word "online," which is known to have many variables (online, Online, OnLine, and online). In JAVA, it should be written as "online."

Not only keywords are case sensitive in JAVA, variables, function names, and all other identifiers must be typed in lower cases.
