- True or false? When an array is passed to a method, a new array is created and passed to the methodwhen an individual array element of an array of type int is passed to a method, it is passed by reference. True False note : in a javaWrite a class ArrayClass, where the main method asks the user to enter the four numbers. Create a method printArray that prints the array whenever required (use Array.toString method). Make the program run as shown in the Sample Run below. Use Array.sort, Arrach.bianrySearch, Array.equals
- java Write a program that calls a method that takes a character array as a parameter (you can initialize an array in the main method) and returns the number of vowels in the array. Partial program is given below. public class CountVowels{ public static void main(String[] args){ char[] arr= System.out.print("There are "+vowels(arr)+" vowels in the array"); }JAVA PROGRAMMING Write a static method named sumOfNegativeNumbers. It must have one parameter, an int array, and an int return type. It should return the sum of the negative numbers in the array. If there are no negative numbers it should return 0. If the array has these values [-1, 2, 5, -3, 7] then it should return -4.Rename the show method to people Override the show method in student and in the other class you created (this will be the polymorphic method) In main program, create an array of 3 objects of class people Instantiate each array position with a different object (people, student, other) With a loop, display all the objects in the array.
- Description: Write a method that return the average of an array with the following header: public static double average(double[] array); In the main method, 5 double numbers are required to be entered. Input Example: 1.2 1.2 1.3 1.3 1.35 Output Example: The average value is 1.27Java: Write a complete method to create an array of random integers. Method Specification The method takes in three integer parameters: the array size, the lower bound, and the upper bound. The method also takes in a boolean parameter. The method creates and returns an integer array of the specified size that contains random numbers between the lower and upper bound., using these rules: The lower bound is always inclusive. If the boolean parameter is true, the upper bound is also inclusive. If the boolean parameter is false, the upper bound is not inclusive (meaning it is exclusive). If any of the parameters are invalid, null is returned. Driver/Tester Program I have provided you with a driver/tester program that you can use to test your code before submitting.

- 1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…Part 1: In Java Write a program that uses a 2-D array to store the highest and lowest temperatures for each month of the year. The program should output the average high, average low, and highest and lowest temperatures of the year. Your program must consist of the following methods with their appropriate parameters: a.) getData: This method reads and stores the data in the 2-D array. b.) averageHigh: This method calculates and returns the average high temperature of the year. c.) averageLow: This method calculates and returns the average low temperature of the year. d.) indexHighTemp: This method returns the index of the highest temperature in the array. e.) indexLowTemp: This method returns the index of the lowest temperature in the array. Use the following input: High temp for each month: 30 40 45 60 70 90 89 95 79 90 70 40 Low temp for each month: 10 -10 20 30 50 75 85 79 50 80 30 20In Java: Ask the user to enter the size of an array. It must be greater than 0. Write a method, inputValidation, that returns the size of the array to the main.
