Problem:

Create a function add(n)/Add(n) which returns a function that always adds n to any number

Note for Java: the return type and methods have not been provided to make it a bit more challenging.

var addOne = add(1);
addOne(3); // 4
var addThree = add(3);
addThree(3); // 6

add_one = add(1)
add_one(3)  # 4

add_three = add(3)
add_three(3) # 6

addOne = add 1
addOne 3 `shouldBe` 4

addOne = add 1
addOne 3 # 4

addOne = add(1)
addOne(3) // 4

Func<double, double> AddOne = Kata.Add(1);
AddOne(3) => 4

...returnType addOne = Kata.add(1);
addOne.method(3) => 4

var addOne = Add(1)
addOne(3) // 4
