I am designing a bank system

Soon as the user opens the display the welcome message alone with all the latest offers are displayed without any input.

afterwards the user is given 4 set of instructions for example:
enter 1, 2, 3 or 4 to display the
1. Display balance
2. print statement
3. Top up
4. Bye

What I am struggling with is how to read the users input and display the instruction?

any help will be nice.

I haven't learn this in class :(

import java.util.Scanner;

public class ScannerNew
    public static void main(String[] args)
        Scanner sc = new Scanner(System.in);
        String input;
        System.out.println("Choose: a,b,c");
            input = sc.nextLine();
            if (input == "a")
                System.out.println("Letter is"+ input);

when I enter a into the display it doesn't output "Letter is a"
