5. Complete the class code below and include a method named partition which takes an integer array and a partition integer as parameters and then partitions the original array into two new arrays where elements of the first array are all less than or equal to the partition integer and the second array are all greater than the partition integer. The method should print the original array, followed by the lower partition and finally the upper partition. Nothing should be returned by the method. For example, given int[ ] arr = {1, 45, 16, 7, 39, 6, 5, 11, 72, 31, 15} a method call to partition(arr, 11) should output: [1, 45, 16, 7, 39, 6, 5, 11, 72, 31, 15] [1, 5, 6, 7, 11] [15, 16, 31, 39, 45, 72] public class Partition { public static void main(String[] args) { int[] arrayToPartition = {1, 45, 16, 7, 39, 6, 5, 11, 72, 31, 15}; int partitionNumber = 11; partition(arrayToPartition, partitionNumber);

With reference to the classes defined question #1, write a method called identifyPersons() that receives an array of Person objects and then displays for each object the following information: name, birthdate, office hours (if the person is Faculty), title (if the person is Staff), class status (if the person is Student), the class name the object belongs to (Person, Employee, Student, Faculty, or Staff). Write a main method to test identifyPersons(). Make sure to call the method and pass array reference containing at least one object from each class.
Create a class containing the main method. In the main method, create an integer array and initialize it with the numbers: 1,3,5,7,9,11,13,15,17,19 Pass the array as an argument to a method. Use a loop to add 1 to each element of the array and return the array to the main method. In the main method, use a loop to add the array elements and display the result. Note: In the loops, use the array field that holds the length of the array and do not use a number for array length.
Create a new class in the practicum1 package named ArrayUtilities. Write a method in the class that meets the following requirements: - It should be named "arrayToString" - It should declare a parameter for an int array. - It should return a String in the same format as the example above, e.g. "[1, 2, 3]". If the array is length 0, you should return the string "[]". - It should NOT use the Arrays.toString() method - you should create and return the string yourself. - You may receive a warning from IntelliJ about using string concatenation. You may ignore it. Write a main method to test your method by calling it with one or more small arrays and printing the string(s). Example output: [] [1, 2, 3] [2, 3, 5, 7, 11, 13]
The Utilities class contains three independent static methods and contains no fields (none should be added).The Utilities class contains the following 3 static methods that you must implement:1. QWERTY – If the argument is null, the length is anything other than 6, or if the element values are outside the inclusive boundof 1 to 7 throw the IllegalArgumentException with the message "Invalid parameter". Otherwise return a char array that hasinput[0] instances of 'Q', followed by input[1] instance of 'W', ....followed by input[5] instances of 'Y'. The length ofthe returned array should be the exact size needed to accommodate all the letters (no smaller or larger).2. turnTo1D – You can assume that the parameter array has at least 1 row and all rows are int array (might be an empty int array)and the parameter delta is a positive integer. The method returns a 1D array (possibly empty array) with all the values inarray that are in the range of the inclusive bound [value – delta to value +…
Create a class named Problem1, and create a main method, inside the main method prompt the user to enter a positive integer n. The program (Java) must error check (keep prompting and reading integers until you get a positive integer n). The program then will create an integer array arr of size n, and fill up that array with random integers between 1 and 500. - Create a method named getMax, which takes an integer array arr and returns an integer, the method should find the maximum value in the integer array arr. - Create a method named getMin, which takes an integer array arr and returns an integer, the method should find the minimum value in the integer array arr. - Create a method named sumValues, which takes an integer array arr and returns an integer, the method should find the sum of all values in the integer array arr. - Create a method named getAverage, which takes an integer array arr and returns a double, the method should find the average of all values in the integer array…
Write (define) a public static method named getInRange, that takes three arguments. The first argument is an Array of int. The second and third arguments will be int values, where the second argument value is guaranteed to be not more than the third argument value. This method must create and return an array of all of the values in the argument array that are between the second and third argument values (inclusive). For example, given the following Array declaration and instantiation: int[] myArray = {1, 22, 333, 400, 5005, 9}; getInRange(myArray, 100, 1000) will return an Array of int with these values {333, 400} Note that the values in the returned array must be in the same order as they are in the argument array. You may wish to write some additional code to test your method. ------------------------------------------------------- public class Main { public static void main(String[] args) { // you may wish to write some code in this main method // to test your method.…
An element in the array is a peak (max or min) if the elements before and after that element are greater than the element itself (min) or the elements before and after that element are less than the element (max). Write a method in your program called displayPeaks that will take a single-dimensional array as parameter and display all peak elements of that array (line by line) together with their index and whether they are max or min. For example, calling the method displayPeaks from main method will display: 83 at position 0 is a max 48 at position 1 is a min 89 at position 2 is a max 40 at position 4 is a min 94 at position 5 is a max 12 at position 8 is a min 87 at position 11 is a max 10 at position 12 is a min 78 at position 14 is a max 2 at position 15 is a min 52 at position 18 is a max 46 at position 19 is a min
JAVA Include Code Comments create a public class named ArrayUtility In ArrayUtility class, create a public static method toString that receives an array of int's, a start string, a separator string and an end string. It returns a String starting with the start string, followed by the array elements separated by the separator and ending with the end string. create a public class named ArrayUtilityTest In ArrayUtilityTest class, create a public static method toStringTest that prints the results for the following 5 lengths of arrays, using different types of brackets and separators for each: empty, singleton, two elements, 5 elements and 20 elements. Call only this class in the main method and check the results. In ArrayUtility class, create a public static method equals that receives two arrays of int's and returns true if they have the same length and equal corresponding elements. In ArrayUtilityTest class, create a public static method equalsTest that prints the results for the…
in Java Develop a method called normalizeGrades() in Java following the details below: The method should accept an array of numeric grades as argument. Each grade in the array is a numeric value (of type double) between 0 to 100. The method should create an integer array of grades, following: If a grade in the array is greater than 50, then the method should round the numeric grade to the nearest integer value using Math.round() method, and then again round it to an integer grade to a nearest multiple of 5. If a grade in the array is less than or equal to 50, then the method should round the numeric grade to the nearest integer value using Math.round() method. The method should create a character array of letter grades, using a switch statement by translating the integer grades created in (b) to an array of letter grades of type character, following the grade notation: 100 or 95 or 90 85: A 70, 75, 80: B 55, 60, 65: C…
