Note: Solve each question as a method. Write a java class called method and three other methods corresponding to each question. termM with a main 1 Write a method to take a String as an input from the user and reverse the String. For example, if the user entered Hello, the method would reverse Hello and print olleH. Example Say, random number generated was 10 The output should look like the following: Frequency of 10 is 3 2 Write a method to generate a random number between 1 and 10. Find the number of times the random number occurs in the following array. Print a message to display the random number and its frequency. [10, 3, 1, 9, 10, 10, 8, 2, 1, 4, 3, 9, 9, 5, 5, 4, 1, 9] 3 Write a method that takes an array of integers and replaces all the 1's in the array with a 0. Call the method in the main method and pass the following array to the method: [10, 3, 1, 9, 10, 10, 8, 2, 1, 4, 3, 9, 9, 5, 5, 4, 1, 9] The method should return an array that looks like the following: [10, 3, 0, 9, 10, 10, 8, 2, 0, 4, 3, 9, 9, 5, 5, 4, 0, 9] Print the elements of the output array.

1. Write a program that takes three numbers (a,b,c) from the user as input and finds the median of the three. The program has a method called median that takes 3 numbers as the parameter and returns the median. Use if-then-else statements to find the median. You can assume the three numbers are not the same. Sample Example: Enter 3 numbers 10 13 The median is 10 public class Median{ public static void main(String[] args){ Scanner input = new int a = int b = int c =
Java program I need help writing a program that has 3 methods: the main method, a method that swaps the digit pairs, and another method that swaps letter pairs. first you would ask the user for a number and call the method that swaps the digit pairs to swap the number shown in the picture. Then ask the user to input a string of letters and numbers and call the method that swaps lettter pairs to swap the letters as shown in the picture. in the method that swaps digit pairs, it accepts an integer for its parameter and then returns a new integer that has each pair of digits swapped in order. if it is an odd number of digits, leave the leftmost digit in its original place. the method that swaps digit pairs shouldnt use the string class. but for the swap letter pairs, it is similar operation as the swap digit pairs method but accepts a string as a parameter and return the swapped string. it can use string class.

Part I: PrintVertical.java Write a program that will prompt the user to enter a sentence (string data), read that sentence into your program as a single string, and then finally process the string by calling the method specified below (vertical). You must process the sentence by calling the method rather than processing the string directly in your main method. Write a void method, vertical, which receives a string as a parameter and prints each letter of the string to the screen on separate lines. Example Execution (user input in green) Please enter a sentence: Hey there! Your sentence printed vertically is: H e t h e r
Prime number is the number that is divided by one and itself only, Twin Prime is a pair of prime numbers that differ by 2. For example, 3 and 5 are twin primes, 5 and 7 are twin primes, and 11 and 13 are twin primes. Write a java program to find all twin primes within a range of 1 up to a number entered by user, such that, that the entered number should be greater than 10. The program has to have a method that takes an integer as a formal parameter and returns if that number is prime or not. Display the output as follows: Enter an integer (greater than 10): 7 Not accepted number! Enter an integer (greater than 10): 50 The number of twin prime numbers up to 50 are: (3, 5) (5, 7) (11, 13) (17, 19) (29, 31) (41, 43)
Homework: Homework01. Write a Java program that prompts the user to enter the seconds as a String (e.g., "1500500500"), converts the received value to long, and displays the number of years and days for the received seconds. For simplicity, assume a year has 365 days. Here is a sample run: Enter the number of seconds: 1500500500 '1500500500' seconds is approximately '4' years and '2766' days
basic java please Write a method starTheString that accepts a string of any size/length and a number. It should then return a new string that is two copies of the string with a set of stars between them equal to the number. For example, the call of starTheString("Hello", 5) o would return "*****Hello*****" 5 stars - Hello - 5 Stars starTheString ("Goodbye", 3) o would return "***Goodbye***" 3 stars – Goodbye - 3 Stars
HangmanAA.java For this program, you will create the game Hangman. (If you are unsure of how to play Hangman, Google it.) The game will start by asking player 1 for a word or phrase (can be multiple words). Then player 1 will be asked how many missed guesses are allowed by player 2. Once this information is received, player 2 will take over. (Have the program print many blank lines of space so that player 2 can’t see what player 1 entered.) The instructions should be displayed for player 2 as well as the number of misses they’re allowed to make before they lose the game. The screen should also output dashes or underscores to represent each letter of player 1’s secret word/phrase. Player 2 should guess one letter at a time. Case should not matter. Typing x or X should give the same result. If that letter is present in the mystery phrase, then it should be displayed. (It will replace the dash/underscore in that spot. Spaces, punctuation, and all other non-alphabetic characters should…
Write a Java program that asks the user to enter a string and counts how many times the letter "s" or "S" appears in the string. Display that number and then display the string that many times. Requirements: Call a method that gets the string from the user. Use recursion to ensure the string has at least 5 characters. Call a method that returns the number of times the letter "s" or "S" appears in the string. This method should use recursion. Call a method that takes the number of times the letter"s" or "S" appeared in the string and display the original string that was obtained from the user that many times using recursion. Call a method that sorts the letters in the string and searches for the letter "m". Display Found or Not Found.
Write a program that removes all non-alphabetic characters from the given input. Ex: If the input is: -Hello, 1 world$! the output is: Helloworld The program must define and call the following method that takes a string as a parameter and returns the string without any non- alphabetic characters. public static String removeNonAlpha (String userString)
