Post Challenge

Comments on "Hello, {name}!"

Parent

"Hello, {name}!"

+3
−2

Background

While we do have a "Hello, World!" challenge, we still don't have one regarding input. So let's do one!

Challenge

Create a program that takes an input (not as a function argument) then outputs Hello, , the variable and ! altogether. Standard I/O only applies. Shortest submission per language wins!

Bonus: Use your username as the input.

Did you even try golfing this? The two variable assignments look entirely useless to me. (3 comments)

user‭ Thanks for catching that. Unfortunately, Scanner is the only way to set an input. At least I got rid of the string assignment.

Scanner is not the only way to take input, although it might be the shortest. That has nothing to do with Scanner s=new Scanner(System.in), though, which you can obviously inline. You're also not allowed to "hide" imports in the header: you need to include them in your bytecount, but here, I'd suggest using java.util.Scanner directly. Finally, using an interface lets you drop public. 118 bytes
