Instructions from your teacher: Write a Java program that prompts the user to enter an integer N and then displays the first N prime numbers. Show a maximum of 10 numbers per line with a spacing of 5; all numbers should be left-aligned. Sample test cases are shown below: 4 The first 4 prime numbers are 2 3 5 7 20 The first 20 prime numbers are 29 2 7 11 13 17 19 23 31 37 41 43 47 53 59 61 67 71 1-1 LO

Extreme Fizz BuzzFizz Buzz is a classic Computer Science problem about Selection. For an integer x, print:• “Fizz” if x is only divisible by 3,• “Buzz” if x is only divisible by 5,• “FizzBuzz” if x is divisible by both 3 and 5,• the number x if it is not divisible by both 3 and 5.This problem is the extreme version of Fizz Buzz. You are given a list of K distinct integers A and a list of K characters S. Both lists are numbered from 1 to K. The integer Ai corresponds to the character Si. Denote B as the subset of A. There will be a rule for each possible subset: if an integerx is only divisible by all elements in B, print a string which is the concatenation of the corresponding character of each element in B, sorted by the index in ascending order. However, if B is an empty subset, print the first digit of x instead. Does it look complicated? Do not worry, as it is just a generalization of the regular Fizz Buzz. For example, if A = [3, 5] and S = [F, B], you will get the normal Fizz…

JAVA PROGRAMMING LAB Write a Java program to takes 2 numbers from the user and print true if one or the other is teen, but not both. "teen" number is that number which lies in the range 13..19 inclusive.
Java code to check if given number is even or odd If number is odd print square of it If number is even print cube of it Take number from user Example 5 -> Square of 5 is 25 2 -> Cube of 2 is 8
Q1: Write a program that reads a set of N integers. Then, the program finds and outputs the sum of the even values and the sum of the odd values of them. For example: if the value entered for N=5, and the five integers are 3, 6, 2, 9, 7. Then the sum of even values (6+2 = 8), and the sum of odd values (3+9+7 = 19) Q2: Write a program that reads some numbers until it reaches a specific value (assume -1 is a stop value in this case). The program should find and outputs the average of all of the numbers (between 10...40) except the stop value (-1). For example: If the numbers look like: 12 5 30 48 -1. Then, the average of the numbers: (12+30)/2 = 21.
GradeProblemUsingSwitch_FamilyName A professor converts numeric grades to letter grades in the following way: Grade Letter Grade 93 – 99 A 87 – 92 B 80 – 86 70 – 79 D 65 - 69 E Using switch, create a java program that reads a numeric grade and output the equivalent letter grade. There should be an error message if the grade entered is invalid. Depicted below are sample outputs when the program is executed (the items in bold characters are inputted by the user, while the items in bold italic characters are calculated and outputted by the program): Enter a grade: 97 Letter Grade: A Enter a grade: 79 Enter a grade: 102 Invalid Input. Letter Grade: D
1. Write a program that lets the user guess whether a randomly generated integer would be even or odd. The program randomly generates an integer and divides it by 2. The integer is even if the remainder is 0, otherwise odd. The program prompts the user to enter a guess and reports whether the guess is correct or incorrect.
Exercise GradesStatistics (Method): Write a program called GradesStatistics, which reads in n grades (of int between 0 and 100, inclusive) and displays the average, minimum, maximum, median and standard deviation. Display the floating-point values upto 2 decimal places. Your output shall look like:Enter the number of students: 4Enter the grade for student 1: 50Enter the grade for student 2: 51Enter the grade for student 3: 56Enter the grade for student 4: 53{50,51,56,53}The average is: 52.50The median is: 52.00The minimum is: 50The maximum is: 56The standard deviation is: 2.29The formula for calculating standard deviation is:Hints:public class GradesStatistics {public static int[] grades; // Declare an int[], to be allocated later.// This array is accessible by all the methods.public static void main(String[] args) {readGrades(); // Read and save the inputs in int[] gradesprintArray(grades);System.out.println("The average is " + average(grades));System.out.println("The median is " +…
Guess The Number Game: write a program that will ask the user to guess a secret numberrandomly generated by your program between 1-10. Player have 3 trials to guess the number.After each trial, you have to inform the user, either he/she has guessed it correctly or not, andthe remaining trials to guess the number. In each trial your program should generate a newrandom number. If user guess at least twice correctly, then shows the message, “you won by 2-1” and vice versa for losing.When game is over, ask the user to play again: If the user types "yes", the game start again.else stop the game.
Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tellsthe ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not.. Test your application with the following ticket numbers: - 123454; is a valid ticket number - 147103; is a valid ticket number -…
A prime number is called a Mersenne prime if it can be writtenin the form 2p - 1 for some positive integer p. Write a program that findsall Mersenne primes with p ≤100 and displays the output as shown below.(Hint: You have to use BigInteger to store the number because it is too big tobe stored in long. Your program may take several hours to run.) p 2^p – 1---------------------2 33 75 31...
