COMP 274 ---- Homework 2 Name: Grade: Question 1: (20 points) Write a method to determine the largest number in 7 numbers. You can use the following methods. int larger(int a, int b) { if (a > b ) { return a; } return b; } int largestInFive(int a, int b, int c, int d, int e) { int temp1 = larger(a, b); int temp2 = larger(c, d); int temp3 = larger(temp1, temp2); return larger(temp3, e); } static int largestInSeven(int a, int b, int c, int d, int e, int f, int g) { // the implimentation. ..... }
Question 2: (20 points) Write a method to change the temperature from Celsius to Fahrenheit. The signature of the method is given as below. static double celsiusToFahrenheit(double C) { // the formula is F = (9/5)*C+32 } Question 3: (20 points) Write a method to calculate the salary of the employee. If the work hours are less than or equal to 40 hours, the salary = hours * rate. However, if the hours are over 40 hours, the extra hours will be paid by 1.5* rate. The signature of the method is given as below. static double getSalary(double hours, double rate) { } Question 4: (20 points) Given an int array, write a method to count the number of even numbers in the array. static int numOfEvenNumber(int[] arr) { //your implemention } Question 5: (10 points) 5.1 What is the difference between static fields and ordinary fields (i.e., the fields without static)? 5.2 What is the difference between static methods and ordinary methods (i.e., the methods without static)? Question 6: (10 points) What is constructor? What is the function of the constructor?
