Write a method that takes an ArrayList of Integer objects and returns an ArrayList of Character objects of the same size. The returned elements of the ArrayList are assigned letter grade corresponding to integer grade of the same index element of the ArrayList parameter (A if 90 or above, F if less than 60). Include code to test your method. [For other letter grades: 80 ?? 89 −> ?, 70 ?? 79 −> ?, 60 ?? 69 −> ?]
public static ArrayList<Character> getLetterGrades(ArrayList<Integer> list){ ArrayList<Character> res = new ArrayList<Character>(); int grade; char output; for(int i = 0;i<list.size();i++){ grade = list.get(i); if(grade>=60 && grade<=69) output = 'D'; else if(grade>=70 && grade<=79) output = 'C'; else if(grade>=80 && grade<=89) output = 'B'; else if(grade>=90) output = 'A'; else output = 'F'; res.add(output); } return res; }

Write a method that given a non-empty ArrayList of Integers parameterand also an Integer parameter, the method returns a new ArrayList containing the elements from the original ArrayList that come after the first occurrence of Integer parameter in the original ArrayList. If the original ArrayList does not contain an occurrence of the Integer parameter return an empty ArrayList . The original ArrayList must be unaffected by the method execution. Following are some examples of the invocation of the method using...
A java exercise please! Write a static method named swapHavles that takes an ArrayList of integers as a a parameter and returns a new ArrayList that has every element in the second half of the original ArrayList swapped with every element in the first half of the original ArrayList. Note: • You can assume that the ArrayList passed to this method as a parameter always contains an even number of elements and will always contain at least two elements. For...
java Write a generic method that takes an ArrayList of objects (of a valid concrete object type) and returns a new ArrayList containing no duplicate elements from the original ArrayList. The method signature is as follows: public static ArrayList UniqueObjects(ArrayList list) Test the method with at least 2 array lists of different concrete object types. Label your outputs properly and show the array lists content before and after calling method UniqueObjects
Using Java, write a program that teachers can use to enter and calculate grades of individual students by utilizing an array, Scanner object, casting, and the print method. First, let the user choose the size for the integer array by using a Scanner object. The integer array will hold individual assignment grades of a fictional student. Next, use a loop to populate the integer array with individual grades. Make sure each individual grade entered by the user fills just one...
Write a method that returns the sum of the elements or an Array-List of Integer objects. Include code to test your method.
2a) Write a method countEvens that takes an ArrayList of String objects as input and returns the number of even length strings contained in the input. For example, if the input is [ one, peach, pear, plum ] then countEvents(inp) should return 2. 2b) Write a method, mirror, that doubles the size of a list of integers by appending a mirror image of the list. For example, given an array list containing [ 1, 5, 2, 6 ], the method...
Design a function named max that accepts two integer values as arguments and returns the value that is the greater of the two. For example, if 7 and 12 are passed as arguments to the function, the function should return 12. Use the function in a program that prompts the user to enter two integer values. The program should display the value that is the greater of the two. Need Variable lists, Psuedocode, ipo chart, Flow Chart, and a python...
SOLVE IN PYTHON:Exercise #1: Design and implement a program (name it AssignGrades) that stores and processes numeric scores for a class. The program prompts the users to enter the class size (number of students) to create a single-dimensional array of that size to store the scores. The program prompts the user to enter a valid integer score (between 0 and 100) for each student. The program validates entered scores, rejects invalid scores, and stores only valid scores in the array....
1. Create a program that takes a numerical score and outputs a letter grade. 2. In this program, create two void functions titled makeScore and theGrade with an int argument. 3. The function makeScore should have a Reference parameter and theGrade should have a Value parameter. Note: Specific numerical scores and letter grades are listed below: 90-100 = Grade A 80-89 = Grade B 70-79 = Grade C 60-69 = Grade D 0-59 = Grade F 4. The function makeScore...
Write a program called printGPA. The program should contain at least 3 methods: main, gradeAverage, and letterGrade. The user will type a line of input containing the student's name, then a number that represents the number of scores, followed by that many integer scores (user input is in bold below). The data type used for the input should be one of the primitive integer data types. Here are two example dialogues: Enter a student record: Maria 5 72 91 84...
