String manipulation

Problem

Write a program that asks the user to enter the name of his or her favorite city. Use a String variable to store the input. The program should display the following:

  • The number of characters in the city name
  • The name of the city in all uppercase letters
  • The name of the city in all lowercase letters
  • The first character in the name of the city

Hint

You can use the following code to get input from the user. You only need to instantiate the Scanner object once:

System.out.println("Please enter some text: ");
Scanner scanner = new Scanner(System.in);
String input = scanner.nextLine();
