# 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!

interface M{static void main(String[]a){System.out.print("Hello, "+new java.util.Scanner(System.in).nextLine()+"!");}}


Try it online!

Golfed 5 bytes thanks to @user's advice.

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

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
