Join Peggy Fisher for an in-depth discussion in this video Overloading functions, part of Up and Running with Java.
- Two or more methods may have the same name…as long as the list of parameters…or the return type is different.…When this happens it's called overloading.…For example, if you wanna write a method…that finds the average of three numbers…you might wanna allow it to use…three integers or three doubles.…The logic is the same,…but the type of data sent by the…calling program is different.…Let's take a look.…Let's start by adding a method…that takes three integer parameters.…My method's gonna be public, static.…
I need to return the average, which will be a double.…The name of my method will be average…and it takes three integers.…Int x, int y and int c.…Inside my method I wanna calculate the average…and return it to the calling program.…Remember, since x, y and z are integers values…I need to change the answer, so I get a double.…So I can do that using either…implicit or explicit conversion.…I'm gonna use implicit conversion.…
Return.…I need to first add the values x + y + z,…then I can divide that by 3.0.…Remember, if I divide by a double…
