I'm a little confused and cannot find out how to write this in code from the UML diagram. I know it's a public class, and its first word is the method. I'm confused about the object array inside the method if it even is inside the method. Thanks for your time.

• getSize(Scanner sc) : Object[]

• friendOrFamily(Scanner sc) : int

CodePudding user response：

There is no array notation in UML. But the closest thing in UML is multiplicity combined with a type name (e.g. Object) :

myarray: Object [*]                
myboundedarray: Object[2..5]
myoptional: Object [0..1] 

This means an unlimited number of objects, a bounded list of objects between 2 and 5 elements, and an optional object that can be absent (minimum 0) or present (maximum 1).

For operations (aka methods), you just indicate it with a column, after the parameter list:

getSize(sc: Scanner) : Object[*]

which describes an operation taking one parameter of type Scanner and returning a container with an undertermined number of elements of type Object.
