Write a Java program using Nested Loops to print the factorials of all numbers between a range of two integers namely start and end. The start/end integers can be zero or any positive numbers and the start should be always less than or equal to end. Appropriate error message should be displayed in case of invalid inputs. Note that a factorial of any integer can be calculated as follows: Factorial of 0 is 1 Factorial of 1 is 1 Factorial of 2 is 2 x 1 =2 Factorial of 5 is 5 x 4 x 3x 2x1= 120 Factorial of N is N x (N-1) x (N-2) x -- x 1 Your program must follow the given Sample Input'Output. Sample Input/Output: Input the start and end numbers: 47 Fact. of 4 is 24 Fact. of 5 is 120 Fact. of 6 is 720 Fact. of 7 is 5040

Write a java program correctly that will accept a single number from a user that you must store in an integer variable. With the use of for loops and nested for loops you must reproduce the specific pattern illustrated in the figures below. After initializing your variables, you are to retrieve a single integer input from the user and then find the appropriate combination of for loops to display each number exactly as displayed in the two samples below.

Create a java program that will compute for n! (Factorial) which is the product of all numbers from 1 to n. Implement using while loop and do while loopNOTE: Starting this activity, you have to apply error trapping. That is, if the input is not a number, your program should prompt the user displaying “Invalid input! Try again.” and should continually ask the user for a correct input before proceeding to the next operation.
solve in java Declare a Boolean variable named allEven. Then, read integer numIn from input representing the number of integers to be read next. Use a loop to read the remaining integers from input. If all numIn integers are even, assign allEven with true. Otherwise, assign allEven with false. Code at the end of main() outputs "All match" if allEven is true or "Not all match" if allEven is false. Ex: If the input is: 3 40 90 60 then the output is: All match Note: Even integers are divisible by 2. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 import java.util.Scanner; public class EvenIntegers { publicstaticvoidmain(String [] args) { Scannerscnr=newScanner(System.in); intnumIn; /* Additional variable declarations go here */ /* Your code goes here */ if (allEven) { System.out.println("All match"); } else { System.out.println("Not all match"); } } }
Write a complete Java program using a while loop structure, name your program Q2. The program prompts the user to enter a series of names, and enters "1" to stop the loop. Output the total number of names entered using a System.out statement. Your sentinel value is "1".
Write a Java program for Zeller’s Algorithm, which can be used to determine the day of the week for any date in the past, present, or future. The program should request the user to enter the date values (month, day, and year). Next, the program should apply the algorithm (see below), and display the appropriate day of the week. The program should loop until the user enters 0 for a month. Use the pre-test while loop with sentinel-value structure while (month!=0). In addition, validate that the month is between 0 and 12; and that day is between 1 and 31. Use the while loop structure for error checking.
bitcount: Given x, set y to the number of bits in x that are 1. Write the code in Java. Provided input(s): x Permitted: 40 operations (may use !, ~, +, -, <<, >>, &, ^, |) Hint: The obvious solution would be something like ans=0; for(int i=0; i<32; i+=1) { a += x&1; x >>=1; } We don’t allow for loops, but even if you replace it with 32 copies that’s still 96 operations, and we only allow 40 for this task. The trick is to do things in parallel, treating a number like a vector of smaller numbers. Suppose I wanted to count the bits of an 8-bit number with bits abcdefgh. With a little shifting and masking I could make three numbers 0b00e00h 0a00d00g 0000c00f and add them to get xx0yy0zz where xx = a+b, yy = c+d+e, and zz = f+g+h. Extending this trick to several rounds on 32 bits will solve this problem.
Write while loops to do the following: Repeatedly print the value of the variable xValue, decreasing it by 0.5 each time, as long as xValue remains positive. Print the square roots of the first 25 odd positive integers. Repeats a block of code as long as the user indicates they want it to. Drive the user crazy by insisting they re-enter a particular input no matter what they enter. Note: In Java Language

Rooter (without the quotation marks) is a new Java program that does the following:An integer named "start" (any value larger than zero) is received from the user when an appropriate prompt is shown.Data validation should be implemented to guarantee that the user delivers an integer that is greater than zero. The user should be given appropriate feedback and allowed to attempt again until acceptable input is obtained if validation is not passed.To locate and show the square roots of all the numbers from "start" to "0," the while loop is used.If the user input 8, you would discover the square root of 8, then the square root of 7, and so on.Each square root should be placed on its own line in the printout.To get the square roots of each number, use the Math.sqrt(double a) method and output the result as a float with four decimal places..
Write a program in C++: Write a program that uses do...while loops to perform the following steps: Prompt the user to input two integers: firstNum and secondNum (firstNum must be less than secondNum). Output all odd numbers between firstNum and secondNum. Output the sum of all even numbers between firstNum and secondNum. Output the numbers and their squares between 1 and 10. Separate the numbers by any amount of spaces. Output the sum of the square of the odd numbers between firstNum and secondNum. Output all uppercase letters.
WRITE A PYTHON PROGRAM Question: 1A perfect number is an integer that is the sum of its positive proper divisors (all divisors except itself). For example, 6 is a perfect number. The divisors of 6 except itself are 1,2 and 3. The sum of the proper divisors of 6 is 6. Thus 6 is a perfect number. You have to take integers as input and continue taking input until the word “STOP” is given as input. After taking the inputs you have to classify the integers as Perfect and Imperfect and store it in a dictionary(Please see the output for better understanding).[Note: You CANNOT use any built in functions EXCEPT input(),range(),print()]Sample Input :61082528100496530STOPSample Output:(No need to follow the output format. Just print the resultant dictionary.){Perfect: [6,28,496],Imperfect: [10,8,25,100,530]}Question: 2Implement the design of the Groceries and Buyer classes so that the following code generates the output below:#Write your code herebuyer1 = Buyer('Ross',…
