Write a Java program that asks the user to enter positive numbers, and store it into (myArray) of type int. Use any letter as a sentinel. Show the sum of all the numbers, total number of numbers and their average.

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?

Write a Java program correctly that generates a report of proof of vaccination against COVID-19 for the peoplewho received their dose of vaccination. Write a program which:1. Display a welcome message.2. Then prompts the user to enter the following:• First name, with first letter uppercase, which is then stores in a variable of type String.• Last name, with first letter uppercase which is then stores in a variable of type String.• Day of birth, set as a number between 1 and 31, which is then stores in a variable of typeint.• Month of birth, set as a number between 1 and 12, which is then stores in a variable of typeint.• Year of birth, set as a number between 1920 and 2006, which is then stores in a variable oftype int.• Day of vaccination, set as a number between 1 and 31, which is then stores in a variable oftype int.• Month of vaccination. set as a number between 1 and 12, which is then stores in a variableof type int.• Year of vaccination, set as a number between 2020 and 2021,…

Please write a java code using the photo below. The second photo is the output of my program that I am writing

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…

Write a code that generates a random lowercase letter. In java programming.  Note: Not a string of letters just one letter is generated every time the program is run. meaning the output should not be something like this: a c t c -that's a random string, it should only be one random letter generated randomly.

THIS IS MEANT TO BE WRITTEN IN JAVA. The assignment is to get an integer from input, and output that integer squared, ending with newline.  Where i'm doing my assignment, in a seperate part of the assignment outside of the code, there's an option that says, "Enter program input ". What do I write?   This is what I have so far and it doesn't run...       import java.util.Scanner; public class NumSquared {public static void main(String[] args) {//main() methodScanner scnr = new Scanner(System.in);//declaring variable to store user inputint userNum;//declaring variable to store square of a numberint userNumSquared;//reading numberuserNum = scnr.nextInt();//multiplying number to it self to find squareuserNumSquared = userNum *userNum;//print square of a numberSystem.out.print(userNumSquared);}   Please explain why it's not running and please show the completed code.

Write expression for JAVA.

Program63.javaWrite a program that estimates the cost of carpet for one or more rooms with rectangular floors. Begin by prompting for the price of carpet per square yard and the number of rooms needing this carpet. Use a loop to prompt for the floor dimensions of each room in feet. In this loop, call a value-returning method with the dimensions and carpet price as arguments. The method should return the carpet cost for each room to main, where it will be printed and accumulated. After all rooms have been processed, the program should display the total cost of the job.Sample Output (image below) Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square.
