An English teacher is checking the length of words his students are using in their written essays. He asked each one of his students to write a sentence and then he need to get the average length of word for each student as he will give a prize for the student who have the maximum average word length. Help the teacher to know the name of the concerned student by implementing a Java program with the following steps: a. Write a Java method called averageStudentWordLength that takes one argument which is a 1D array of String of name sentence and return the average length of the sentence as a double value. b. Write a Java method called averageAllStudentWordLength that takes one argument which is a 2D array of String of name allStudentsSentence contains the sentences written by all students in the class and return the (as 1D array of double) the average word length for each of the sentence of student. This should be done by repeatedly calling the method averageStudentWordLength defined and…

The input parameters n and d will always be greater than 0.arrow_forwardWrite a Java method that generates and returns a random number between 2 valuesreceived as parameters. You must consider 2 cases when there are or not differencebetween values (please refer to slide 43 from 04 Methods). The function should checkif the difference is strictly positive otherwise replace it with the value 1.Test your method using main as follows (bold values are input by the user):Lowest value: 60Highest value: 100Diff. between values: 5Number of random numbers: 5060 90 70 65 70 60 75 100 100 8580 90 60 95 75 65 80 70 90 9085 65 95 60 85 95 75 85 60 7090 80 65 65 90 90 80 60 95 7560 90 70 70 90 60 65 60 85 60arrow_forward
- Write a java method that receives two integers called n1 and n2 and then returns the number of rotations of digits to the left or to the right so that n1 and n2 becomes the same. if not possible the method returns your student ID number.arrow_forwardWrite a Java program that asks the user to enter a string and counts how many times the letter "s" or "S" appears in the string. Display that number and then display the string that many times. Requirements: Call a method that gets the string from the user. Use recursion to ensure the string has at least 5 characters. Call a method that returns the number of times the letter "s" or "S" appears in the string. This method should use recursion. Call a method that takes the number of times the letter"s" or "S" appeared in the string and display the original string that was obtained from the user that many times using recursion. Call a method that sorts the letters in the string and searches for the letter "m".

- Write a java method sumOfAllOddNumbersBetween() that takes as input two integers and returns the sum of all odd numbers that are between the two given numbers (the given numbers should be excluded from the sum). Write a main program to test your method by accepting the two integers from the user.arrow_forwardWrite a recursive method called digitCount() that takes a positive integer as a parameter and returns the number of digits in the integer. Hint: The number of digits increases by 1 whenever the input number is divided by 10. Use Java. Ex: If the input is: 345 the method digitCount() returns and the program outputs: 3 Ex: If the input is: 0 the method digitCount() returns and the program outputs: 1 import java.util.Scanner; public class LabProgram {/* TODO: Write recursive digitCount() method here. */public static void main(String[] args) {Scanner scnr = new Scanner(System.in);int num, digits;num = scnr.nextInt();digits = digitCount(num);System.out.println(digits);}}arrow_forwardWrite a Java application that calculates the sum of a series of integers that are passedto method sum() using a variable-length argument list.

- Write a Java program Primes that finds all possible prime numbers in the range of (1, n], where 1 < n ≤ 1000. Solve the problem by implementing and using the helper method isPrime(number) which determines whether the given argument is prime or not. Example: Input 5 Output 2 3 5 (Consider the structure of the code that is given in the picture. The structure must be the same)arrow_forward3. Write a Java program to implement a method which prints the Fibonacci series up to nth term. The value of n will be taken from the user in the main() method.Fibonacci series starts with 0 and 1, and the sum of previous two numbers is the next number of the series. For instance, 0, 1, 1 (0 + 1), 2 (1 + 1), 3 (1 + 2), and so on.Sample output [assuming the number of term (n) is 8]:The Fibonacci series: 0 1 1 2 3 5 8 13arrow_forwardWrite a recursive method in java that returns a string that contains the octal representation of a positive integer. Test your method. Hint: An octal number is the base-8 number system, and uses the digits 0 to 7. For example, the number 12 can be converted to octal number as follows: Divide by 8, the remainder represents the first digit so 12/8 = 1 and the remainder is 4 so the first digit is 4. The quotient is 1. Then we divide 1 over 8 we get zero and the remainder is 1. The second digit is 1 and we stop. The equivalent octal number for 12 is 14.arrow_forward
