In java: Develop a function that accepts an array of integers and returns their average. Develop a function that accepts an array of integers and a threshold value from the user. The function returns how many values in the array are strictly greater than the cutoff. Using the functions written for #1, #3, and #4, find the number of values above average in two randomly generated arrays. Develop two functions:a. a function that returns the index of the maximum value in an array of integers passed by a caller, the caller prints the returned index and the value at that indexb. a function that returns the index of the alphabetically first value in an array of strings, the caller prints the returned index and the value at that inde Develop two functions:a. a function that swaps the alphabetically first value in an array of Strings with the first value in the array. Call this function twice on two different arrays of Strings; in the caller, use the function written for #2b to display…
Write a Java program: A palindromic number or palindrome number is a number that remains the same when its digits are reversed. Like 16461. Write a Java program that implements the helper method isPalindrome() that decides whether a given int number is a palindrome or not. Do not use ready String class functions like reverse() or arrays and array functions!!! Input FormatA line contains an Integer N. Constraints 1 <= N <= 999999 Output FormatA text containing either "This number is a palindrome" or "This number is not a palindrome" (the code should have the structure as in the picture)
In java there must be at least two calls to the function with different arguments and the output must clearly show the task being performed. (ONLY ARRAYS or ARRAYLIST) Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks. Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8,…

Each enum constant (I, IV, ..., M) is declared with its decimal value, which can be accessed with the function getValue().

Given an integer array of positive single digit values such as:int a[] = {8,4,2,6,9};1) Write a recursive arrayToN function which returns the concatenation of all array values as an integer value.This function should accept all required data as parameters and return a long integer value.ExamplesIf the array is 8 4 2 6 9 the arrayToN function returns the integer 84269.If the array is 0 2 6 8 9 3 5 1 the arrayToN function returns the integer 2689351.
in java Integer numVals is read from input and integer array userCounts is declared with size numVals. Then, numVals integers are read from input and stored into userCounts. If the first element is less than the last element, then assign Boolean firstSmaller with true. Otherwise, assign firstSmaller with false. Ex: If the input is: 5 40 22 41 84 77 then the output is: First element is less than last element 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 import java.util.Scanner; public class UserTracker { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumVals; int[] userCounts; inti; booleanfirstSmaller; numVals=scnr.nextInt(); userCounts=newint[numVals]; for (i=0; i<userCounts.length; ++i) { userCounts[i] =scnr.nextInt(); } /* Your code goes here */ if (firstSmaller) { System.out.println("First element is less than last element"); } else { System.out.println("First element is not less…

Write a program that: a. computes the size of a group when a square in the group is given b. computes the numbers of different groups c. lists all groups Example: userInput.txt: 0 0 0 0 0 0 0 0 0 10 0 0 1 1 0 0 0 0 10 0 0 0 0 0 0 0 0 00 0 0 0 1 0 0 1 0 00 0 0 1 0 0 0 1 0 00 0 0 0 0 0 0 1 1 00 0 0 0 1 1 0 0 0 00 0 0 0 0 0 0 0 0 00 0 0 0 0 0 0 0 0 00 0 0 0 0 0 0 0 0 0 The program should output three things: The size of the group in which location specified by the user belongs. then if the user enters 1,2 the answer is 0 1,4 the answer is 2 3,4 the answer is 1 4,7 the answer is 4 The number of each size group Size Count 2 3 1 List of each group’s locations 1: (0,9) (1,9) 2: (1,3) (1,4) 3: (3,4) 4: (3,7) (4,7) (5,7) (5,8) 5: (4,3) 6: (6,4) (6,5)

Language: JAVA Script Your company is giving every employee earning less than $50,000 a 10% raise! *Write a function 'employeeRaises(peopleObj)' that takes an array of objects s containing employee names and their salaries and returns an array containing the employees that need raises, along with their new salaries. Example: employees [ {name: "Alice", salary: 80000}, {name: "Bob", salary: 48000 }, {name: "Carol", salary: 60000}, {name: "Dan", salary: 78000}, {name: "Ellen", salary: 100000}, console.log(employeeRaises (employees) ); // [ { name: 'Bob', salary: 44000 } ] funcation emplyeeRaises(employees){ |// Your code here} /****DO NOT MODIFY ANYTHING UNDER THIS LINE****/ try{| module.exports = employeeRaises;}catch (e) {|module.exports=null;}
5.17 LAB: Word frequencies (JAVA) Write a program in java that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain fewer than 20 words. Ex: If the input is: 5 hey hi Mark hi mark the output is: hey - 1 hi - 2 Mark - 1 hi - 2 mark - 1 Hint: Use two arrays, one array for the strings and one array for the frequencies.
