In your program, write a method that accepts a positive integer and returns true if the number is a prime number and false otherwise. Note that 2 is the only even prime number. An odd integer is prime if it not divisible by any odd integer less than or equal to the square root of the number. Part2: A prime number whose reversal is also a prime number is called emirp. For example, 11, 13, 79 and 359 are emirps. Write a program that outputs to a ListBox the first 100 emirps. Your program must contain the method from Part 1 that returns true if a number is prime; false otherwise and another method that returns the reversal of a positive number. You can reverse the integer in the following way: • Convert the integer into a string value = num.ToString(); • Use the following code to reverse the integer string newNum = “”; for (int l = value.Length; l > 0; l--) newNum = newNum + value[l-1]; Also, your program should have a TextBox that will accept a positive integer from the user and then display whether the positive integer if an emirp

Prime Numbers A prime number is a number that can be evenly divided by only itself and 1. For example, the number 5 is prime because it can be evenly divided by only 1 and 5. The number 6, however, is not prime because it can be evenly divided by 1, 2, 3, and 6. Write a Boolean method named IsPrime that takes an integer as an argument and returns true if the argument is a prime number or false otherwise. Use the method in an application that lets the user enter a number and then displays a message indicating whether the number is prime.
Palindrome Detector: a palindrome is any word, phrase, or sentence that reads the same forward and backward. Here are some well-known palindromes: Able was I, ere I saw Elba A man, a plan, a canal, panama Desserts, I stressed Kayak Write a Boolean method that uses recursion to determine whether a String argument is a palindrome. The method should return true if the argument reads the same forward and backward. Demonstrate the method in a program.
Financial Application:• Write a program that computes future investment value at a given interest rate for aspecified number of months and prints the report shown in the sample output. • Given the annual interest rate, the interest amount earned each month is computedusing the formula: Interest earned = investment amount * annual interest rate /1200 (=months * 100) • Write a method, computeFutureValue, which receives the investment amount, annualinterest rate and number of months as parameters and does the following: o Prints the interest amount earned each month and the new value of theinvestment (hint: use a loop). o Returns the total interest amount earned after the number of months specified bythe user. The main method will:o Ask the user for all input needed to call the computeFutureValue method.o Call computeFutureValueo Print the total interest amount earned by the investment at the end of thenumber of months entered by the user.

Use Java programming language Write a program that asks the user to enter 5 test grades (use an array to store them). Output the grades entered, the lowest and highest grade, the average grade, how many grades are above the average and how many are below and the letter grade for the average grade. Create a method that returns the lowest grade. Create a method that returns the highest grade. Create a method that returns the average grade. Create a method that returns how many grades were above the average. Create a method that returns how many grades were below the average. Create a method that returns the letter grade of the average (90-100 - A, 80-89 - B, 70-79 - C, < 70 - F)

JAVA Problem description:You are to write a program called Seasons that prompts the user for a month and day and displays the season in which that date occurs. For reference, we will use the following date cutoffs for the various seasons: Winter December 21 – March 19 Spring March 20th – June 20th Summer June 21st – September 20th Fall September 21st – December 20th Data Validation For this program, you'll write a specific method to perform data validation based on the month and day entered. More specifically: Month – the month entered must be a valid month of the year (January – December). Day – the day entered must be a valid day for that month: January, March, May, July, August, October, December have 1-31 days. April, June, September, November have 1-30 days. February has 1-28 days (do not worry about leap years) Required program decomposition String getMonth(Scanner console) This method is called from the main method and should prompt for the month as a string…
Method: sumOdds(value: int): This method will sum all the odd values from 1 upto the value passed by parameter. This will display the sumas an integer value.Method: characterCount(phrase: str): This method will count the number of characters in the phrase that is passed by parameter. You cannot useany built in function ( ie len() ) and must use a looping activity. This should display the number of characters inthe phrase as an integerMethod: multiplicationPractice(): This method is to practice simple multiplication problems. The program should randomly generate twonumbers from 1-10 for the user to multiply. It should display the multiplication problem and allow the user toanswer the problem. It should display if the user got the answer correct or incorrect. The activity shouldcontinue until the user has gotten 3 different practice problems correct.Method: order(value1: int, value2: int, value3: int): This method is to order the 3 passed value from least to greatest.

basic java please Write a void method named emptyBox()that accepts two parameters: the first parameter should be the height of a box to be drawn, and the second parameter will be the width. The method should then draw an empty box of the correct size. For example, the call emptyBox(8, 5) should produce the following output: ***** * * * * * * * * * * * * ***** The width of the box is 5. The middle lines have 3 spaces in the middle. The height of the box is 8. The middle columns have 6 spaces
Java Program Chapter 5. PC #13. is Prime Method A prime number is a number that is evenly divisible only by itself and 1. For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Demonstrate the method in a complete program. The program should ask the user to enter a number for primality test or a negative number to exit. Tip: Recall that the % operator divides one number by another, and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2. I do not want a goodbye system out in the program and it has to pass all the test cases. Test Case 1 Please enter a number to check for primality or -1 to exit:\n2ENTER2 is a prime…
Microsoft Visual C# 7th edition, programming exercise 11-3 Instructions: Write the program FindSquareRoot that finds the square root of a user’s input value. The Math class contains a static method named Sqrt() that accepts a double and returns the parameter’s square root. If the user’s entry cannot be converted to a double, display an appropriate message, and set the square root value to 0. Otherwise, test the input number’s value. If it is negative, throw a new ApplicationException to which you pass the message “Number can’t be negative.” and again set sqrt to 0. If the input value is a double and not negative, pass it to the Math.Sqrt() method, and display the returned value. An example of the program is shown below: Enter a number 9 Square root is 3 or Enter a number -9 Error: Number can't be negative. Square root is 0 Here is my code. How can I pass the message to a new ApplicationException and display the error message? Thank you. using System; using static System.Console;…
