PrimeAA.java Write a program that will tell a user if their number is prime or not. Your code will need to run in a loop (possibly many loops) so that the user can continue to check numbers. A prime is a number that is only divisible by itself and the number 1. This means your code should loop through each value between 1 and the number entered to see if it’s a divisor. If you only check for a small handful of numbers (such as 2, 3, and 5), you will lose most of the credit for this project. Include a try/catch to catch input mismatches and include a custom exception to catch negative values. If the user enters 0, the program should end. Not only will you tell the user if their number is prime or not, you must also print the divisors to the screen (if they exist) on the same line as shown below AND give a count of how many divisors there are. See examples below. Your program should run the test case exactly as it appears below, and should work on any other case in general. Output…

Write a program that asks a user to input the height of triangle and draw a triangle that has the following pattern. Use nested loops for this problem. If the user enter height as 4 Then the triangle output is 1 1 2 1 2 3 1 2 3 4 We make the following assumptions • There is no space between the margin and first number in each row • There could be a space after the last number on every line • There is pne space between numbers on every line • There maybe a newline at the end of last line There is one test-case to check your code, there are two hidden testcases that tests correctness of your code 376584 2469

In java, create a program that will use a do while loop with a "yes/no" prompt. The program should include user input and output with getters and setters. Once the end of the loop is reached, ask the user if they'd like to do the program again. Answering "Yes" will start the program over again. Answering "No" will end the program. Answering with anything else will be an invalid input. Once the loop begins again, the program should also discard all previous inputs so that there won't be any overlapping. Use Scanner.nextLine();, it will help.

Write a program that uses nested loops to display a pattern like the examples below. It must not use any formatting operators (e.g., string concatenation) to print the strings to the terminal. Example pyramid-1: #... ##... ###... ####... #####... Example pyramid-2: ##### ####.. ###.... ##...... #........ ..........

JAVA   A perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. A divisor of an integer x is an integer that can divide x evenly. Take an integer n as input from the keyboard, print true if n is a perfect number, otherwise, print false. You do not need to print any explanation, just print true or false. Use a for loop to generate the divisors. Example 1: Input: num = 28 Output: true Explanation: 28 = 1 + 2 + 4 + 7 + 14 1, 2, 4, 7, and 14 are all divisors of 28.   Example 2: Input: num = 6 Output: true   Example 3: Input: num = 496 Output: true         Example 4: Input: num = 8128 Output: true   Example 5: Input: num = 2 Output: false

In Java how to write loop inside a loop for instence "for loop" inside a "while loop" can I have sample with code

You have been hired by a local organic sod company to write coverage calculator for their website. Organic sod is cut into rectangles 9 square foot in area for lawn installation. Your program will prompt the customer for the length and the width of a rectangular area being covered with sod. Implement the following "pseudocode" to obtain the number of pieces to order. • Compute the area of the rectangle to be covered • Divide the area by 9 • Convert the result to an integer and then add 1 Below is a sample run with Python output in blue and user input in black. Enter length:200 Enter width:40 You should order 889 pieces.

Active buzzer project: Write an algorithm for the below code for all steps. Then write a conclusion (test&debug) for the code. Also, write comments for the code explaining each line.

JAVA Write a program that plays a number-guessing game to guess a secret number randomly generated within the range 1 and 10. The user will get as many numbers of tries as he/she needs to guess the number. Tell the users if their guess is right or wrong and if their guess is wrong let them try to guess the number again. You have solved a similar problem in a previous lab using a while loop.   You must generate the secret number using the Java Random class. When the user guesses a number he/she will have to take an input of his guessed number from the keyboard. The user will have to take as many inputs as needed to guess the correct secret-number. That means the code will keep looping as long as the guess is different from the secret number. You also need to count the number of tries and report the count at the end. Use a do-while loop to prompt the user to guess again if the guess is wrong. Make sure that it doesn't mess up the output if you guess the secret number on the first try.…
