Please help using java Create a method to check for valid input andanother for displaying the mark ranges. Callboth methods from the main.4. Write a function type method called phoneListthat accepts as a parameter a name consisting ofthe first and last name, and returns a string in theform of last name, first name. For example, if thename is "Verna Guru", then the stringproduced should be "Guru, Verna".Create aprogram that uses this method. The programshould allow the user to enter several names untilthey want to end.s. When entering passwords, the computer oftenreturns hiding characters that hide the passwordthat is entered.Write a program that hides the words entered by auser with a character of your choice. Spacesshould not be hidden. For example, if the userenters the string “All gophers are named Fred",and your chosen character is “*", the output ofthe program should be "*** *******************". Your program should use two methods inaddition to the main method. The first calledhideChars takes in a String and a character ofyour choice and returns a String of thosecharacters. The second calledisASpace takesin a char and returns true if it is a space and falseif it is not.

Implement the class Character The role should be “primary” or “secondary” all other values are not acceptable. Considercapital and small letters variance. The gender should be “m” or “M” for male or “f” or “F” for female. The age should be a positive value. The giveRaise method increase the salary of a character by a given percentage with amaximum salary of 10000. The toString method returns a string that describes the character. For example: [Elisabeth Kane, female, 35, primary,4500$] 2) Implement the class Play A Play can have at most 20 characters. The real number of characters is registered in nbOfCharacters and is updated automaticallywhen a new character is added. AddCharacter method adds a new character to the characters array and updates thenbOfCharacters value. The attribute nbPlay keeps track of the number of Plays created. The toString method returns a string description of the play including name, genre and thenames of all the characters.Example: [The Opera…
Create a code that tracks how many times a phrase appears in a string. A number should be the function's output value. Never presume that a series of words can contain punctuation and only one space between words. Create the method so that it accepts a String argument or a StringBuilder object as a parameter.
You can check whether a string is a substring of another string by using the find method in the str class. Write your own function to implementfind. Write a program that prompts the user to enter two strings and then checks whether the first string is a substring of the second string.
2. Write a method isPalidrome(String arg) that determines if a String is palindrome or not. Palindrome is when a String remains the same after reversing. The method should return boolean type. For example: MADAM is palindrome.
Create a function that tallies the number of times a phrase appears in a string. The function's output should be a number. Don't presume that a single space divides words, and that a string can contain punctuation. Create the method so that it can accept a String input or a StringBuilder object.
Program62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below)
You are responsible for adding the appropriate testing code to your main. a. The getValedictorian method returns the valedictorian of the class, that is the student with the highest grade point average. Implement this new method. b. The getHonorsPercent method returns the percentage of students in the class who are in the honors program. Use 3.75 as the cutoff GPA. Implement this method. Also print the list of students, by using the isHonor method, in the Honors program. c. An alternate implementation for the School class is being considered, in which the students are stored in an ArrayList instead of an array. Show how the declaration of the data field students would look in this alternate design. MAIN CLASS: import java.util.ArrayList; public class Main { public static void main(String[] args) { System.out.println("Unit07Project2 by Your Name"); System.out.println(); int size = 10; School onw = new School(size); /* Add the code…
Method called reverse that reverses a string passed to this method as a parameter and returns the reversed string. Eg reverse(“string”) should return “gnirts”. Print out the reversed string in your main method. Hint: Use CharAt or Substring methods from the String Class.
Create class that performs different functions on Strings that are sent to it. All the methods you create will be static. Only two methods (mentioned below) and the main method need to be public. Any other methods that you write to help these methods should be private because they are only used internally within the class. Requirements: 1. Prompt users to enter 3 string inputs. Consider strings with alphabetic characters (a - z, A - Z) and/or numbers (0 - 9) as valid. Strings contain only non-word characters are invalid. Print the following usage when an input string is invalid or is empty. Usage: Enter a string that contains alphabetic characters and numbers 2. Create a method "isPalindrome" that takes a String as a parameter and returns true if the given String parameter is a palindrome and false if it is not. In your main method, this method should be call with the first user input and print either "The given string is a palindrome." or "The given string is not a palindrome." as…
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
public static String reversevowels (String text) Given a text string, create and return a new string of same length where all vowels have been reversed, and all other characters are kept as they were. For simplicity, in this problem only the characters aeiouAEIOU are considered vowels, and y is never a vowel. For example, given the text string "computer science", this method would return "cempetir sceunco". Furthermore, to make this problem more interesting and the result look more palatable, this method must maintain the capitalization of vowels based on the vowel character that was originally in the position that each new vowel character is moved into. For example, "Ilkka Markus" should become "Ulkka Markis" instead of "ulkka MarkIs". Use the handy utility methods in the Character wrapper class to determine whether some particular character is in upper- or lowercase, and convert a character to upper- or lowercase as needed.
You are given two Strings, "HelLo" and "hello". Use two appropriate methods of String class to check if they are equal. The output of first method should be that they are not equal. And the output of the second method should be that they are equal. Partial code is given below to help you complete this question. You can ignore this entirely and write your own code, if you like. public class StringComparison public static void main(String) args)M String s1 - "HeLLo": String s2- "hello": System.out.printin(.
