- City and State. Extract the city name and state from strings like “Utica, NY” and “Los Angeles, CA”. Assume the state is always the last two characters in the string, the city name has at least one character, there is a comma following the city name, and a single space after the comma. Use the split method to separate the city name from the state (Notice the city name will still have a comma at the end).

Break the input string up into two strings, one containing thefirst name and one containing the last name. You can do that by using the indexOf()subroutine to find the position of the space, and then using substring() to extracteach of the two names. Also output the number of characters in each name andoutput the user’s initials. (The initials are the first letter of the first name togetherwith the first letter of the last name.) A sample run of the program should looksomething like this:Please enter your first name and last name, separated bya space.?

When shopping for groceries, it's helpful to know how much it's going to cost you in advance - this helps you avoid an embarrassing situation in the check-out line. For this assignment, you're going to write a simple program that asks you for the name, quantity, and price of two grocery store items. It will then generate a grocery list for you, complete with the total price. (Later in the semester, we'll learn how to make a program that can create much larger lists, but we'll start small here). Call the file Assignment1B (with a file extension of .cpp, .cs or .java) Sample Output: What're you buying? Ice Cream How many? 2 What do they cost? 2.25 What else're you buying? Celery How many? 5 What do they cost? 1.74 Your list: Ice Cream (2) $2.25 ($4.50 total) Celery (5) $1.74 ($8.7 total) Total Cost: $14.2 using Java programmingarrow_forward
