A validation method that takes in the message (as a string) and the offset integer entered by the user. The method should return "true" if the offset is between 0 and 26 inclusively and the message contains only letters and spaces. If it fails either criteria, it should return "false". • If the validation method returns true, a second encryption method should be called. This method also takes in the message (as a string) and the offset integer entered by the user. It should convert the message to UPPERCASE, encrypt every letter in the message, and leave the spaces as they were. It should then return the encrypted message.

Write a program that reads two phrases on separate lines and outputs one of the four responses: 1) Phrase one is found within phrase two 2) Phrase two is found within phrase one 3) Both phrases match 4) No matches Hint: Use the String method indexOf(). Ex: If the input is: fire firetruck the output is: fire is found within firetruck Ex: If the input is: the green grass grows green grass the output is: green grass is found within the green grass grows Ex: If the input is: pick a card pick a card the output is: Both phrases match Ex: If the input is: apples oranges the output is: No matches(in java please)

A magic date is one when written in the following format, the month times the date equals the year e.g. 6/10/60. Write code that figures out if a user entered date is a magic date. The dates must be between 1 - 31, inclusive and the months between 1 - 12, inclusive. Let the user know whether they entered a magic date. If the input parameters are not valid, return false. examples: magicDate(6, 10, 60) -> truemagicDate(50, 12, 600) -> false

In C# code: Write a program that will help an elementary schoolstudent learn multiplication. Use a Random object to produce two positive one-digitintegers. The program should then prompt the user with a question, such asHow much is 6 times 7 The student then inputs the answer. Next, the program checks the student’s answer. Ifit’s correct, display the message "Very good!" and ask another multiplication question.If the answer is wrong, display the message "No. Please try again." and let the studenttry the same question repeatedly until the student gets it right. A separate methodshould be used to generate each new question. This method should be called oncewhen the app begins execution and each time the user answers the question correctly.Program will stop any time students enter -1. One problem in CAI environments is student fatigue. This can be reduced by varyingthe computer’s responses to hold the student’s attention. The program should usevarious comments to be displayed for each...

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)

Write a method that finds the number ofoccurrences of a specified character in a string using the following header:public static int count(String str, char a) For example, count("Welcome", 'e') returns 2. Write a test program thatprompts the user to enter a string followed by a character then displays the numberof occurrences of the character in the string.
