STEP 1

Ask the name.

Scanner reads what a person has printed. Before the Main class, add import, and inside the main, create Scanner for System.in.

import java.util.Scanner;
Scanner input = new Scanner(System.in);

✦ import connects the finished tool Java.

STEP 2

Get the text.

nextLine is waiting for a whole line. Save it to String and show it to me. Close the Scanner after work.

String name = input.nextLine();
System.out.println("Привет, " + name);
input.close();

Talking.
