Case in java10/4/2023 ![]() Snake case is also a good choice for naming files, as it keeps names readable. Snake case is used for creating variable and method names. Here are some examples of how you would use the snake case: number_of_donuts = 34 When using snake case, all letters need to be lowercase. Snake case separates each word with an underscore character ( _). Let's see each case in more detail in the following sections. That way, your code will remain readable, easy to understand, and maintainable for yourself and other developers you may be working with on a team. It is best practice to choose one case style and stick with it. When choosing a case style, keep in mind the best practices of the programming language you are using in your project.Īnd no matter which case you choose, remain consistent in your project. When it comes to using case styles, there is no definite answer as to which one is the best. ![]() Specifically, there are certain naming conventions available across all programming languages, also known as: And there are a few ways available to combine them. Number, of, and donuts are treated separately from each other because of the space character in between them.įor your program to work correctly, you need to remove all the spaces and combine the words into a single string in a specific way. Most (if not all) programming languages interpret each word as a completely separate thing and a single unit. If you tried the above, you would get an error. Say you want to create a variable in your program, and the name of the variable is more than just one word.įor your program to not crash, you cannot leave spaces between the different words when creating the variable.įor example, you cannot do the following: number of donuts = 34 In programming, spaces are reserved characters. In this article, I will explain the differences between the most widely used case types in programming. ![]() Indeed, naming things when programming can be challenging when you have different naming conventions available. “There are 2 hard problems in computer science: cache invalidation, naming things, and off-by-1 errors.” As a software engineer, you may be familiar with the following quote by Leon Bambrick:
