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)

JAVA CODE PLEASE Using conditional and looping structures, make a simple calculator that does the following: First, the program should get a single string ? from the user, so that it knows what type of operation it is supposed to perform. If ? is "negate", obtain one number from the user, then negate the number. Output the negated number. If ? is "add", obtain two numbers from the user, then add the two numbers. Output the sum. similar goes to "subtract" & "multiply" division is excluded If ? is "max", obtain two numbers from the user, then get the larger value between the two numbers. If the numbers are equal, output any of them. Input: The first line of input contains a single integer ? (1≤?≤10), which is the number of operations you have to perform. This is followed by a single line containing ? operations separated by a single space. The start of each operation contains a string (which can be negate, add, subtract, multiply or max). If the string is negate, this will be…
JAVA PPROGRAM ASAP Please create this program ASAP BECAUSE IT IS MY LAB ASSIGNMENT so it passes all the test cases. The program must pass the test case when uploaded to Hypergrade. Chapter 9. PC #2. Word Counter (page 608) Write a method that accepts a String object as an argument and returns the number of words it contains. For instance, if the argument is “Four score and seven years ago” the method should return the number 6. Demonstrate the method in a program that asks the user to input a string and then passes it to the method. The number of words in the string should be displayed on the screen. Test Case 1 Please enter a string or type QUIT to exit:\nHello World!ENTERThere are 2 words in that string.\nPlease enter a string or type QUIT to exit:\nI have a dream.ENTERThere are 4 words in that string.\nPlease enter a string or type QUIT to exit:\nJava is great.ENTERThere are 3 words in that string.\nPlease enter a string or type QUIT to exit:\nquitENTER
In python Add the following four methods to your Crew class: move(self, location): This takes in a location as a string, along with self, and attempts to move the crew member to the specified location. If location is one of the five valid location options ("Bridge", "Medbay", "Engine", "Lasers", or "Sleep Pods"), then this should change self.location to that new value. Otherwise, the function should print out the message: Not a valid location. repair(self, ship): first_aid(self, ship): fire_lasers(self, ship, target_ship, target_location): The above three methods represent tasks that a basic Crew member is not capable of (but one of its derived classes will be able to accomplish). So each of them should simply print out a message of the form: <Name> doesn't know how to do that. Examples: Copy the following if __name__ == "__main__" block into your hw12.py file, and comment out tests for parts of the class you haven’t implemented yet. if __name__ == '__main__': crew1…

Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Write a program that takes a string and an integer as input, and outputs a sentence using the input values as shown in the example below. The program repeats until the input string is quit and disregards the integer input that follows. Ex: If the input is: apples 5 shoes 2 quit 0 the output is: Eating 5 apples a day keeps the doctor away. Eating 2 shoes a day keeps the doctor away. user_text word = "" while True:user_text = input().split()word = (user_text[0])if word == 'quit':breaknumber = (user_text[1]) print('Eating {} {} a day keeps the doctor away.'.format(number, word))

Practice / Frequency of Characters Write a method that returns the frequency of each characters of a given String parameter. If the given String is null, then return null If the given String is empty return an empty map Example input: output: empty map explanation: input is empty Example input: null output: null explanation: input is null. Since problem output is focused on the frequency we can comfortably use Map data structure. Because we can use characters as key and the occurrences of them as value. Example input: responsible output: {r=1, e=2, s=2, p=1, o=1, n=1, i=1, b=1, l=1} explanation: characters are keys and oc values ences are
Task 4: public class Palindrome TestWrapper final String isMsq = "IS a palindrome"; final String isNotMsq- " is NOT a palindrome"; public static void main(String args[]) new PalindromeTestWrapper(); public PalindromeTestWrapper() // your code here 1 public boolean isPalindrome ( Strings ) 1 // your code here Using the code defined above, complete the isPalindrome method so that it returns true if s is a palindrome and false if it isn't. You must use a stack in your solution algorithm.
