Exam 1z0-811 topic 1 question 48 discussion

According to Java naming conventions, the correct method identifier from the options provided is: B. calculateBill Here's a breakdown of the naming conventions in Java: Classes should be named using PascalCase (also known as UpperCamelCase), where each word starts with a capital letter (e.g., BillCalculator or Calculator). So A and D are valid class names, not method names. Methods should be named using camelCase (also known as lowerCamelCase), where the first word is lowercase and subsequent words start with an uppercase letter (e.g., calculateBill). Thus, B is correct. C. calculatebill uses all lowercase letters for the second part of the identifier, which does not follow the camelCase convention, making it incorrect. So, B is the only correct answer for a method identifier according to Java naming conventions.
