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.
Do not use static variables to implement recursive methods.
USING JAVA:
// P6
public static int countSubstrings(String s1, String s2) {
}
Write a recursive method countSubstrings that counts the number of non-overlapping occurrences of a string s2 in a string s1. 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.
Show the output on the following strings:
s1 = “Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture.…

- 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.arrow_forwardWrite a java program for the following: Create an integer array with 10 numbers. Apply the Linear Search method to find a target using Recursive method. Try to use a scanner to input the target value. Give different target values which shows both successful and not successful of searching method.arrow_forwardWrite 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]. Do not use loops.(java code)arrow_forward
- Write a recursive method that takes as parameter as array of type double (num) and the length of the array (len). The method should display the square root of numbers that are greater than 10.0 in the array. The method prototype is: public static void display(double [] num, int len); You may use sqrt method that is defined in the Math class.arrow_forwardCreate 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_forwardsolve it without using Arrays and the method should take int and return a String Write 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
- java Write a recursive function with two parameters: an array of ints and the number of elements in the array. The function will return the sum of all positive values in the array. Do not add any negative array elements to the sum. You can add another parameter to the function if you wish.arrow_forwardWrite a recursive method that parses a binary number as astring into a decimal integer. The method header is public static int bin2Dec(String binaryString) Write a test program that prompts the user to enter a binary string and displaysits decimal equivalent.arrow_forwardCreate a Java class RecursiveMethods.java and create the following methods inside: ALL THE METHODS NEED TO BE COMPLETED RECURSIVLY. NO LOOPS ALLOWED. - oddEvenMatch Rec: 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 , 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. After completing the methods, use the main method to test them. You can hard code the tests.arrow_forward
