Java – when do I create a getter method without “get” in its name?

2020-08-21 • Java

The following questions have bothered me for a long time. I can't find any information about naming conventions

There are methods, such as:

java.util.Collection.size();

This method is actually a getter of the size of a collection, but it does not start with "get" like the conventional getter method

So what is the naming convention for these types of methods?

Solution

Collection. Size () is not a typical getter because it is not a simple field return - it is the size of a collection, so you don't have SetSize () because it's not the field you set - it's a "calculated" value

You can think like this - getters and setters are usually used together to encapsulate a field - if you can't do setx (), it's not a typical getter / setter

But this is just a matter of convention. Some people believe that it is always used without getting or setting it
