write a program (its name should be StudentPoll.java) that first reads an integer, N, for the number of responses from students and then creates an array of N elements of type int to store the responses. Use SecureRandom to generate N random integers of values between 3 and 10 inclusive as the response values (i.e., the survey values) for the array. The program should print out the distribution of the survey like the following outputs. public class StudentPoll {public static void main(String[] args) {// student response array (more typically, input at runtime)int[] responses = {1, 2, 5, 4, 3, 5, 2, 1, 3, 3, 1, 4, 3, 3, 3, 2, 3, 3, 2, 14};int[] frequency = new int[6]; // array of frequency counters // for each answer, select responses element and use that value// as frequency index to determine element to increment for (int answer = 0; answer < responses.length; answer++) { try { ++frequency[responses[answer]]; } catch (ArrayIndexOutOfBoundsException e) { System.out.println(e); //…

in java You are required to build a class ArithematicProblem that represent a binaryarithematic problem such as addition, subtraction, multiplication and division.The ArithematicProblem class is a super class which is there to provide the mostgeneric version of the ArithematicProblem concept. This class has followinginstance variables1. Operand1 (double)2. Operand2 (double)3. Answer(double)4. Error(boolean)The value of Operand1 and Operand 2 will be initialized through parameters in theconstructor while the value of answer is Double.POSITIVE_INFINITY and error is falseby default.Provide getters for all but setters for only operand1 and operand2Provide the toString method so that the string representation of each operationthe standard representation in mathematics i.e. if its an addition problem then itshould be printed as 2 + 3 = 5 and so on.Provide a method double solve() in this class. This method performs the arithematicoperation on the operands, calculates answer, sets the value of…
Write a program that will read a line of text and output the number of words in the line and the number of occurrences of each letter. Define a word to be any string of letters that is delimited at each end by either whitespace, a period, a comma, or the beginning or end of the line. You can assume that the input consists entirely of letters, whitespace, commas, and periods. When outputting the number of letters that occur in a line, be sure to count uppercase and lowercase versions of a letter as the same letter. Output the letters in alphabetical order and list only those letters that occur in the input line. For example, the input line I say Hi. should produce output similar to the following: 3 words 1 a 1 h 2 i 1 s 1 y

Write a Java program that reads each line of an input file workshop.txt that consists of a city name followed by a climate conditions like (temperature, Humidity, Wind) and save it in arrayList. The program then will decide whether it's possible to conduct a workshop in the city or not depending on the following conditions in sequence: • If the temperature >20 and Humidity is not low, then it's possible to conduct a workshop. • If the wind is normal and temperature is greater than 30 then it's possible to conduct a workshop. Save the results in a file called results.txt. You need to create class Decision that will be able to take the suitable decision based on weather conditions. This class will also validate the content of the input file such that each line represents city record in the following format (input file records must all follow this format): City: temp, humidity, wind. For example, if the workshop.txt contains Muscat: 25, high, strong. Suhar: 20, high, normal Salalah: 15,…

write a java class definition 4. Give the class definition of ArrayChecker which has an integer array variable arr. This has 2 methods a. Constructor which take an integer parameter numElements and reads all the numElements from the user using Scanner class into arr. b. public boolean checkConsecutiveValues (int n), which checks whether arr has atleast n consecutive elements with the same values. (it is enough if it returns the first occurrence of n consecutive elements) (Write only the class definition of ArrayChecker) Eg. 12345555 10, if n = 4, this has four consecutive 5s, return true 10 12 111 11456666. If n = 3, this has 3 consecutive 1s, return true. 10 12 111 11456666. If n = 7, then return false
