Can a method have multiple arguments?
Multiple Arguments You can actually have your variable arguments along with other arguments. That is, you can pass your method a double, an int, and then a String using varargs. It might seem silly to have multiple arguments in a method that already takes multiple arguments.

How many arguments should a method have?
The ideal number of arguments for a function is zero (niladic). Next comes one (monadic), followed closely by two (dyadic). Three arguments (triadic) should be avoided where possible. More than three (polyadic) requires very special justification – and then shouldn’t be used anyway.
What are method arguments in Java?
