Java:
Write a recursive method that finds and returns the sum of the elements of an int array. Also, write a program to test your method.
Write a recursive method that returns thelargest integer in an array. Write a test program that prompts the user to enter alist of eight integers and displays the largest element.
java
Write a recursive method largestDigitthat accepts an integer parameter and returns the largest digit value that appears in that integer. Your method should work for both positive and negative numbers. If a number contains only a single digit, that digit's value is by definition the largest. The following table shows several example calls:
Call
Value Returned
largestDigit(14263203)
6
largestDigit(845)
8
largestDigit(52649)
9
largestDigit(3)
3
largestDigit(0)
0
largestDigit(-573026)
7
largestDigit(-2)
2
Obey the following restrictions in your solution:
You may not use a String, Scanner, array, or any data structure (list, stack, map, etc.).
Your method must be recursive and not use any loops (for, while, etc.).
Your solution should run in no worse than O(N) time, where N is the number of digits in the number.

- Write a recursive method that gets three parameters as input: an array of integers called nums, an integer called index,and an integer called The purpose of this method is to return true if value is stored in the array starting at nums[index]. That is, you have to check if value is equal to nums[index] or nums[index +1] or nums[index +2 ] …. nums[nums.length -1].

Use the method indexOf() from String class. As an example, with s1=”abab” and s2=”ab”, countSubstrings returns 2. With s1=”aaabbaa” and s2=”aa”, countSubstrings returns 2. With s1=”aabbaa” and s2=”AA”, countSubStrings returns 0.

- Create a Java class RecursiveMethods.java and create the following methods inside: ALL THE METHODS NEED TO BE COMPLETED RECURSIVLY. NO LOOPS ALLOWED. - oddEvenMatchRec: the method takes an integer array as a parameter and returns a boolean. The method returns true if every odd index contains an odd integer AND every even index contains an even integer(0 is even). Otherwise it returns false. - sumNRec: The method takes an integer array A and returns the sum of all integers in the parameter array. - nDownToOne: Takes an integer n and prints out the numbers from n down to 1, each number on its own line. - inputAndPrintReverse: Inputs integers from the user until the user enters 0, then prints the integers in reverse order. For this method, you may NOT use an array or any type of array structure, in other words, you may not use any structure to store the user input.arrow_forwardwrite a code in java (using recursion)arrow_forwardJAVA Phone numbers and PIN codes can be easier to remember when you find words that spell out thenumber on a standard phone pad.
