Write a program that has the following methods: (1) a method that takes an array of integers, returns the second-largest element in the array. public static int secondMax(int [ ] a) (2) a method that takes an array of integers, return true if the array is sorted in increasing order. public static boolean isSorted(int[] a) (3) a method that checks if the elements of a two dimensional array are identical. public static boolean isIdentical(int[][] a) (4) a method public static ArrayList sum(ArrayList a, ArrayList b) that returns the sum of the two array lists. It adds the corresponding the elements of the lists, if one list is shorter than the other, then add as long as you can and then append the remaining elements from the longer list. For example, if a is 1 4 9 16 and b is 9 7 4 9 11 then sum returns the array list 10 11 13 25 11 (5) a main method, that test each of the methods that you define above, make sure you test all possible cases.

In this lab, you complete a prewritten c++ program for a carpenter who creates personalized house signs. the program is supposed to compute the price of any sign a customer orders, based on the following facts: the charge for all signs is a minimum of $35.00. the first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. if the sign is made of oak, add $20.00. no charge is added for pine. black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. instructions ensure the file named housesign. cppis open in the code editor. you need to declare variables for the following, and initialize them where specified: a variable for the cost of the sign initialized to 0.00 (charge). a variable for the number of characters initialized to 8 (numchars). a variable for the color of the characters initialized to "gold" (color). a variable for the wood type initialized to "oak" (woodtype). write the rest of the program using assignment statements and ifstatements as appropriate. the output statements are written for you. execute the program by clicking the run button. your output should be: the charge for this sign is $82. this is the code, // housesign. cpp - this program calculates prices for custom made signs. #include #include using namespace std; int main() { // this is the work done in the housekeeping() function // declare and initialize variables here // charge for this sign // color of characters in sign // number of characters in sign // type of wood // this is the work done in the detailloop() function // write assignment and if statements here // this is the work done in the endofjob() function // output charge for this sign cout < < "the charge for this sign is $" < < charge < < endl; return(0); }

Assume a class window with accessor method getwidth that accepts no parameters and returns an integer. assume further an array of 3 window elements named winarr, has been declared and initialized. write a sequence of statements that prints out the width of the widest window in the array.
