Write a Java program that implements static method roundSum() so that given 3 ints: a, b, and c; return the sum of their rounded values. We'll round an int value up to the next multiple of 10 if its rightmost digit is 5 or more, so 15 rounds up to 20. Alternately, round down to the previous multiple of 10 if its rightmost digit is less than 5, so 12 rounds down to 10. roundSum(16, 17, 18) → 50 roundSum(12, 13, 14) → 40 roundSum(6, 4, 4) → 10   The examples of input and output you can see in the picture. (the code structure should be as in the second picture)

I have two matrices, for example, as follows: Matrix 1: 2 4 3 1 6 7 5 8 9 Matrix 2: 5 5 3 1 6 6 5 3 8 Write a program to check if these two matrices are the same (i.e. to see if each number in matrix 1 equals to its corresponding number (same row same column) in matrix 2). If they are the same, display “same matrices”; otherwise display “different matrices”. Using java programming

Write a java method that takes four integers as arguments (int a, int b, int c, int d), that prints Match if and only if at least three values match otherwise, it prints No Match.

A pet shop wants to give a discount to its clients if they buy one or more pets and at least four other items. The discount is equal to 15 percent of the cost of the other items, but not the pets. Implement a method: public static void discount (double[] prices, boolean[] isPet, int nItems) The method receives information about a particular sale. For the ith item, prices[i] is the price before any discount, and isPet[i] is true if the item is a pet. Wite a program that prompts a cashier to enter each price and then a y for a pet orn for another item. Use a price of -1 as a sentinel. Save the inputs in an array. Call the method that you implemented, and display the discount.

Write a Java program to make two arrays containing random integer values (You can make these arrays with specific sizes using the below makeRandomArray method). The program should sum these two arrays and prints the resulted array (the array that contains the result of the two arrays summing). The program should also show the maximum element of the resulted array. Your program must define and call the following methods to perform the program as illustrated above: 1- A method int [] makeRandomArray(int size ,int a , int b) that makes and returns an array with specific size. The methods fills this array with random integers in a range [a..b] 2- A method public static int findmax(int x[ ]) that finds the maximum value of a number of x array passed to the method. 3- A method public static void printArray(int x[ ]) that prints the elements of the array x passed to the method. 4- A method public int[ ] sumTwoArrays(int x[ ], int y[ ]) that sums the elements of the two arrays(x and y…

In Python, Solve the locker riddle which reads as follows:Imagine 100 lockers numbered 1 to 100 with 100 students lined up in front of those 100lockers:The first student opens every locker.The second student closes every 2nd locker.The 3rd student changes every 3rd locker; if it’s closed, she opens it; if it’s open, she closes it.The 4th student changes every fourth locker (e.g., 4th, 8th, etc.).The 5th student changes every 5th locker (e.g., 5th, 10th, etc.).That same pattern continues for all 100 students.  Which lockers are left open after all 100 students have walked the rowof lockers?

Is there a way to create a java program on Branching and selecting method on problems like this? Suppose that we are working for an online service that provides a bulletin board for its users. We would like to give our users the option of filtering out profanity. Suppose that we consider the words cat dog and rabbit to be profane.  Write a program that reads a string from the keyboard and test whether the string contain any one of these words.  Your program should find words like cAt that differ only in case.   Have your program reject only lines that contain one or more of the three words exactly.  For example, concatenation is a small category should not be considered profane.    This problem can be solved easily.  If you add a space to the beginning of the string and a space at the end of the string you only need to check if space cat space or space dog space or space rabbit space is in the string. Use three if statements; one for each word. If one or more of the words are there set…

Needs to be written in java: Write a program with a main() method that asks the user to input an integer array of 10 elements.Next, create three methods described below. From inside your main() method, call each of thethree methods described below and print out the results of the methods 2, 3, which return values.1. printReverse() - a method that receives an array of integers, then reverses the elements ofthe array and prints out all the elements from inside the method. Print all in one lineseparated by commas (see sample output below).2. getLargest() – a method that receives an array of integers, then returns the largest integervalue in the array. (print result from main())3. computeTwice()- a method that receives the previously reversed array of integers, thenreturns an array of integers which doubles the value of each number in the array (see thesample output below). (print result from main())Sample output:Enter a number:22Enter a number:34Enter a number:21Enter a number:35Enter a…

Define the method printValue() that takes two integer parameters and outputs the product of all integers starting with the first and ending with the second parameter, followed by a newline. The method does not return any value. Ex: If the input is 3 7, then the output is: 2520 Note: Assume the first integer parameter is less than the second. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16     import java.util.Scanner;   public class ValuePrinter {   /* Your code goes here */   publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumber1; intnumber2;   number1=scnr.nextInt(); number2=scnr.nextInt(); printValue(number1, number2); } }
