How would I solve this in Java? it has to: return a string for the day of the week, param offset -the offset from Thursday, and return the name of day of the week.

Write a program to compute the sum of the first N Fibonacci numbers, where N is an integer that is input by the user.  Once it computes the sum, the program will prompt the user for a new value of N.  The program will exit if the user enters a non-integer number or string (such as “quit”) instead of an integer.  Language: Java The first four numbers of the Fibonacci sequence are: 0, 1, 1, and 2. Use For loop at least once, can use while loops. Sample Output: Welcome to the Fibonacci AdderTo quit, enter a non-integer number or string How many Fibonacci numbers should be summed? >> 10The sum of the first 10 Fibonacci numbers is: 88 How many Fibonacci numbers should be summed? >> xxx Thank You for Using the Fibonacci Adder

THIS IS IN JAVA. A restaurant serves breakfast before 11 am, after which they serve lunch. Which expression for XXX outputs the correct string for any time? Variable time ranges from 0 to 23 (e.g., 13 means 1 pm). mealString=XXX;// Output mealString         A. (time > 11) ? "Breakfast" : "Lunch" B. (time == 11) ? "Breakfast" : "Lunch" C. (time < 11) ? "Breakfast" : "Lunch" D. (time != 11) ? "Breakfast" : "Lunch"

please use java to answer the following question

I need help with this Java problem as it's explained in the image below:  Palindrome (Deque) A palindrome is a string that reads the same backwards and forwards. Use a deque to implement a program that tests whether a line of text is a palindrome. The program reads a line, then outputs whether the input is a palindrome or not.   Ex: If the input is: senile felines!   the output is: Yes, "senile felines!" is a palindrome.     Ex: If the input is: rotostor   the output is: No, "rotostor" is not a palindrome.   Ignore punctuation and spacing. Assume all alphabetic characters will be lowercase. Special case: A one-character string is a palindrome. Hint: The deque must be a Deque of Characters, but ordinary chars will be automatically converted to Characters when added to the deque.   Java Code:    import java.util.Scanner; import java.util.LinkedList; import java.util.Deque; public class LabProgram {       public static void main(String[] args) {         Scanner scnr = new…
