    Question Request of code for Problems and assignments

    could you help me to write this question?

    The Fibonacci numbers are a sequence of integers in which the first two elements are 1, and each
    following element is the sum of the two preceding elements. The mathematical definition of each kth
    Fibonacci number is the following:

    F(k )={ F(k−1)+F(k−2), k>2
    1, k≤2

    The first 10 Fibonacci numbers are: 1 1 2 3 5 8 13 21 34 55
    Write a Java program that uses a for loop to compute and print the first 20 Fibonacci numbers.

    Question Methods with Parameters & Scanner Objects

    could you help me to solve this question?

    Write a Java program that has a method called quadratic which solves quadratic equations and prints
    their roots. Quadratic equation is a polynomial equation in terms of a variable x of the ax^2+ bx + c = 0.
    The formula for solving a quadratic equation is:

    x=−b±√b^2−4 ac/2a

    Some example equations and their roots are:
    x^2 – 7x + 12 (a = 1, b = -7, c = 12): the roots are x = 4, and x = 3
    x^2 – 3x + 2 (a = 1, b = -3, c = 2): the roots are x = 2, and x = 1
    The program should prompt for the values of coefficients a, b and c from a user by using Scanner object. Then, the method quadratic() should accept these coefficients as parameters and should printthe roots of the equation.

    Question Text Processing

    could you help me to solve this question?

    Write a Java program that has a method called printPalindrome which accepts a Scanner object for the console as a parameter, prompts the user to enter one or more words, and prints whether the entered String is a palindrome (i.e., reads the same forward as it does backward, like “adanada”, or “racecar”). The method should treat the given String as case-insensitive, so that words like “MaDam” and “RacECAR” will be considered palindromes.

    Question Method with a return value & Conditional Execution

    could you help me to solve this question?

    Write a Java program that has a method called season() which takes as parameters two integers representing a month and day, and returns a String indicating the season for that month and day. Assume that the month is specified as an integer between 1 (for January) and 12 (for December). Likewise, the day of the month is a number between 1 and 31 (you may consider each month has 31 days, for simplicity). If the given date falls between 12/16 (i.e., December/16) and 3/15 (March/15), the method should return “Winter”. If the date falls between 3/16 (i.e., March/16) and 6/15 (i.e., June/15) , the method should return “Spring”. If the date falls between 6/16 (i.e., June/16) and 9/15 (i.e., September/15) , the method should return “Summer”. And, finally, if the date falls between 9/16 (i.e., September/16) and 12/15 (i.e., December/15) , the method should return “Fall”. The season() method should use conditional statements (e.g., if/else if/…) to determine the result. The program should prompt for month and day information from a user, by using a Scanner object.

    Question Find the mistakes java exercise

    The following method attempts to return the median (middle) of three integers, but it contains logic errors. In what cases does the method return an incorrect result? How can the code be fixed?
    public static int medianOf3(int n1, int n2, int n3){
    if(n1 < n2){
         if (n2 < n3){
                return n2; 
                } else{
                return n3;
              }
                }else{
                if(n1 < n3){
                  return n1;
                      }else{
               return n3;
                }
                      }
             }

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.

    What have you tried to do to solve this problem?

    Before writing any code, work out in English what steps are required to solve the problem.

    Forget about writing any code.
    How would you solve the problem with 3 coins of different values laid on a table in a row left to right. How would you compare them (two at a time) to find the position of the coin of middle value?
    After two coins are compared, what does that tell you about one of the coins possibly being the middle one?
    What further test and results are needed to find the middle coin?

    Hint: The middle coin will be greater than one of the other two coins and less than the other coin.
