- Make simple java program with a method that returns an array. The method will accept an input a comma-separated string with three values from a user. The array will store each value in a different element. Use try..catch error handling and print possible failure messages and print success from within method if execution is successful. Call the method from the main method of the program to demonstrate its functionality by looping through the array and printing the individual values. -Please answer with screenshots of the code, input, and outputConsider the method headings: void funcOne(int [ ] alpha, int size) int funcSum(int x, int y) void funcTwo(int [ ] alpha, int [ ] beta) and the declarations: int [ ] list = new int [50]; int [ ] Alist = new int [60]; int num; Write Java statements that do the following: a. Call the method funcOne with the actual parameters, the array list and 50, respectively. b. Print the value returned by the method funcSum with the actual parameters, the thirtieth and tenth components of list, respectively. c. Call the method funcTwo with the actual parameters, the array list and array Alist, respectively.Answer the given question with a proper explanation and step-by-step solution. Can someone tell me why I'm getting Java error cannot invoke add(int) on array type int on the bold line? I need this method to calculate median based on file that will be input in a different method. Do no change to a main method as I need to reserve that to only have a contructor. public int Problem7(File file) throws FileNotFoundException { int[] listInt; try { Scanner scanner = new Scanner(file); while (scanner.hasNextLine()) { String value = scanner.nextLine(); listInt.add(Integer.parseInt(value)); System.out.println(value); } scanner.close(); } catch (Exception ex) { ex.printStackTrace(); } Arrays.sort(listInt); int middle = listInt.length/2; int median = 0; if (listInt.length%2 == 1) median = listInt[middle]; else median = (listInt[middle-1] + listInt[middle]) / 2; return median; }}
- Need help with java problem. Start with the java file below and add the following methods:1. Add the methodpublic int getLastIndex(T item) which returns the index of the last entry which is equal to item. If item is not found, it returns -1. 2. Add the method public boolean equals(Object other) that returns true when the contents of 2 objects are the same. java file:JAVA Which is true about arrays and methods? A. Arrays cannot be passed to methods B. Passing an array to a method creates a copy of the array within the method C. An array is passed to a method as a reference D. A programmer must make a copy of an array before passing the array to a methodImplement the below pseudo-code in a Java program using a while loop and aswitch-case statement. The program should be well structured, and the taskperformed under each option (at least options 'b' to 'e') should be implementedas a separate method.NOTE: The Scanner class does not have a method to input a character. Inorder to read a character from the keyboard, use one of the following methods(after declaring the Scanner object):static Scanner kb = new Scanner(System.in);1. char ch = kb.nextLine().charAt(0); OR2. char ch = kb.nextLine().toLowerCase().charAt(0);where kb is a Scanner class object.The second method above also converts the input to lowercase, which is oftenuseful. Though these methods allow the user to input more than one characteron the input line, the rest of the line (after capturing the first character withcharAt(0)) is discarded.If you also want to ignore the leading spaces before the first character thenuse:1. char ch = kb.nextLine().trim().charAt(0); OR2. char ch =…
- Please complete the task by yourself only in JAVA with explanation. Don't copy. Thank you. Only finish the (d) question, Thank you ! Using quicksort to sort an array of car objects by various criteria. Define a class Car as follows: class Car { public String make; public String model; public int mpg; // Miles per gallon } a) Implement a comparator called CompareCarsByMakeThenModel that can be passed as an argument to the quicksort method from the lecture notes. CompareCarsByMakeThenModel should return a value that will cause quicksort to sort an array of cars in ascending order (from smallest to largest) by make and, when two cars have the same make, in ascending order by model. b) Implement a comparator called CompareCarsByDescendingMPG that can be passed as an argument to the quicksort method from the lecture notes. CompareCarsByDescendingMPG should return a value that will cause quicksort to sort an array of cars in descending order (from largest to smallest) by mpg. c)…FOR JAVA Write a Java class named Book, which has a name, an author and a pub- lisher. This class must also have a static field (an array with length 100) which holds names of all constructed books, and a static method which returns the number of constructed books.Solve below java problem please. You are given a list of Employee objects and you need to implement a method that returns the top n highest-paid employees. class Employee { private String name; private double salary; public Employee(String name, double salary) { this.name = name; this.salary = salary; } public String getName() { return name; } public double getSalary() { return salary; } }
