When a method is called from the main method then, it calls itself four times and the depth of the recursion will be four.
Hence, the correct option is “B”.
Explanation of Solution
Four:
The depth of the recursion depends on the number of times the method calls itself.
Explanation for incorrect options:
One:
The depth of the recursion depends on the number of times the method calls itself and it is given that the method calls itself four times.
Hence, option “A” is wrong.
Five:
The depth of the recursion depends on the number of times the method calls itself and it is given that the method calls itself four times.
Hence, the option “C” is wrong.
Nine:
The depth of the recursion depends on the number of times the method calls itself and it is given that the method calls itself four times.
Hence, the option “D” is wrong.

- 1. Create a Java program with three static methods in addition to the main method 1) Factorial Method (recursion method to calculate the factorial of an integer number) 2) Fibonacci Medhod (recursion method to calculate the fibonacci of an integer number) 3) Display Method (take a String and integer mumber as parameters then display the factorial sequence if the String = "Factorial" and display fibonacci sequence if String = "Fibonacci". Otherwise, display "Invalid choice input") Guideline for developing the application. Input Output Start program by invoking the Display method then test is run: Fibonacci (6) -> 0 11 2 3 5 8 13 Factorial (5) -> 5 * 4 * 3 * 2* 1 - 120 with the following values: - 13 Display("Fibonacci", 6); Invalid choice input: test BUILD SUCCESSFUL (total time: 1 second) Display("Factorial", 5); Display("test", 5):arrow_forwardUse Java programming language Write a program that asks the user to enter 5 test grades (use an array to store them).

T OR Farrow_forwardUsing JAVA Recursive Power Method Write a method called powCalthat uses recursion to raise a number to a power. The method should accept two arguments: The first argument is the exponentand the second argument is the number to be raised(example”powCal(10,2)means2^10). Assume that the exponent is anonnegative integer. Demonstrate the method in a program called Recursive (This means that you need to write a program that has at least two methods: mainand powCal. The powCal method is where you implement the requirements above and the main method is where you make a method call to demonstrate how your powCalmethod work).arrow_forward
- JAVA Problem description:You are to write a program called Seasons that prompts the user for a month and day and displays the season in which that date occurs. For reference, we will use the following date cutoffs for the various seasons: Winter December 21 – March 19 Spring March 20th – June 20th Summer June 21st – September 20th Fall September 21st – December 20th Data Validation For this program, you'll write a specific method to perform data validation based on the month and day entered. More specifically: Month – the month entered must be a valid month of the year (January – December). Day – the day entered must be a valid day for that month: January, March, May, July, August, October, December have 1-31 days. April, June, September, November have 1-30 days. February has 1-28 days (do not worry about leap years) Required program decomposition String getMonth(Scanner console) This method is called from the main method and should prompt for the month as a string…arrow_forwardPlease code in python Forbidden concepts: recursion, custom classes Create a program that takes a university student’s name, their 1st parent’s income, and their second parent’s income. If the average income between the parents is $40,000 or below, then it would put them into a Tuition Grant list. If it’s above, then it would be a Full Tuition Required list.

- If your first name starts with a letter from A-J inclusively: Write a recursive method that takes a string as argument and determines if the string has more vowels than consonants. Test the method by asking the user to enter a string. Hint: Write your recursive method to first count vowels and consonants.arrow_forwardJAVA Question 2: For two integers m and n, their GCD (Greatest Common Divisor) can be computed by a recursive method. Write a recursive method gcd(m,n) to find their Greatest Common Divisor. Method body: If m is 0, the method returns n. If n is 0, the method returns m. If neither is 0, the method can recursively calculate the Greatest Common Divisor with two smaller parameters: One is n, the second one is m mod n (or m % n). The recursive method cannot have loops. Note: although there are other approaches to calculate Greatest Common Divisor, please follow the instructions in this question, otherwise you will not get the credit. main method: Prompt and read in two numbers to find the greatest common divisor. Call the gcd method with the two numbers as its argument. Print the result to the monitor.

For example if you call it with 10, it would return 30 because 10+8+6+4+2=30 Write a RECURSIVE method called sumEven It must take in an int (the max you wish to sum to) It must return an int (the sum) If it's passed in an even number it should sum the number passed in with all the even numbers before it. For example if passed 8, it would sum 8+6+4+2=20 If it's passed an odd number it should still sum only the EVEN numbers. What we mean is that sumEven(9) should return 8+6+4+2=20. Not 9+7+5+3+1. Hint: You'll have an if statement with the base condition, an else if for even and an else if for odd. In the case of odd, just call yourself with the next lowest even number. In your main method, open a file called "Carlton.txt" for writing. Use a loop to call the method above multiple times and print a line to the file for each iteration of the loop: The sum of even numbers up to 0 is 0 The…arrow_forward
