Question

Is each of the following method identifiers (a) legal and conventional, (b) legal but unconventional, or (C) illegal?

Answer 1

Identifiers are indeed the identifiers of variables, functions, classes, packages, or interfaces. These are not the objects themselves, as contrasted to literals, but rather means of alluding to things, and the further calculation can be defined as follows:

legal and conventional:

• The class identification whose names starting with just an uppercase letter includes no space.
• It stresses each subsequent word with an uppercase letter that falls within legal and customary.
• The example are "association Rules(), getReady(), and displayTotal()".

legal but unconventional:

• The class identification whose new words do not begin with initial uppercase letters, utilizing underscore.
• It marks the whole letter ​with uppercase, and commencing the first letter with lowercase is regarded as legal but unusual.
• The example are "PayrollApp(), Accounts_Receivable()".

illegal:

• Class IDs with a space between two words, reserved keywords, names that begin with numbers, and symbols (except $,_) are prohibited.
• The example are "void(), Golden Retriever(), invoice#(), 36542ZipCode()   and 911()".
