Load your bag with some initial values, but do not fill it. Your client code should give the user the option to: display the contents of the bag using the class method “toVector” add values to the bag remove values from the bag sort the bag search for a value using their choice of either the iterative search or the recursive search - both need to be tested Allow the user to keep doing these things until they are done. Do not automatically sort the bag if the user chooses to search. Your program should give the user a message telling them they must first sort the bag before they can search.You decide what the user interface will be. Make it clear and easy to use. It can be very basic; nothing fancy. A menu driven program works well. Each value in your array should be unique - no value will appear in the array multiple times. Your array elements can be any data type – use a template class put in place in the code provided. You can write your client code to process a bag holding any…
hello im stuck on a problem and it would be great if you could create a program that prompts the user for a message to encode,as well as an offset to encrypt it with. You will then create and use the following methods:• A validation method that takes in the message (as a string) and the offset integerentered by the user. The method should return “true” if the offset is between 0and 26 inclusively and the message contains only letters and spaces. If it failseither criteria, it should return “false”.• If the validation method returns true, a second encryption method should becalled. This method also takes in the message (as a string) and the offset integerentered by the user. It should convert the message to UPPERCASE, encryptevery letter in the message, and leave the spaces as they were. It should thenreturn the encrypted message. i attached an image of the sample output
Mailings Review View Help AaBbC AaBbCcD AaBbCcD AaBbCc Aa Heading 1 T Normal 1No Spac. Heading 2 Hea Paragraph Styles 8. Consider the following equation for the sum of a finite arithmetic series: S, = n(a, ta where n is the number of elements in the series, a is the first element of the series, and a, is the last element of the series. Write a method that returns the sum of the elements stored in the array in 8 above. The array must be passed to the method as an argument. Your solution should implement the equation for the sum S.
Simple try-catch Program This lab is a simple program that demonstrates how try-catch works. You will notice the output when you enter incorrect input (for example, enter a string or double instead of an integer). Type up the code, execute and submit the results ONLY. Do at least 2 valid inputs and 1 invalid. NOTE: The program stops executing after it encounters an error! CODE: import java.util.Scanner; public class TryCatchExampleSimple { public static void main(String[] args) { Scanner input = new Scanner(System.in); int num = 0; System.out.println("Even number tester.\n"); System.out.println("Enter your name: "); String name input.nextLine(); } } while (true) { try { System.out.println("Enter an integer : "); num= input.nextInt (); } int mod = num%2; if (mod == 0) " System.out.println(name + else " System.out.println(name + num = 0; } catch (Exception e) { break; > System.out.println("ERROR: The number you entered is illegal!"); System.out.println("Exception error: "+e.toString());…
What is the return value of “ corona”. Substring(0,3)
Passwords that are created by users are usually very simple and easy to guess. Create a Python program that takes a simpler pswrd + makes it stronger by taking characters using the rules below, and by appending "!" to the ending of the input string. i becomes 1 a becomes @ m becomes M B becomes 8 s becomes $ Example: If the input is: mypassword the output is: Myp@$$word! Hint: Python strings are immutable, but support string concatenation. Store and build the stronger password in the given password variable This is what I have so far.... word = input()password = ''
Python: Vowel: Display a vowel selected at random.

Alert ⚠️ You guys use AI tool to answer. Last time I found plagiarism and AI detection in my answer. Now If you will use these things I'll surely give multiple downvotes and will report sure.
Add Fractions problem: create in a sandbox environment. Directions: In this program you will ask the user for 4 integers that represtent two fractions. First ask for the numerator of the first and then the denominator. Then ask for the numerator and denominator of the second. Your program should add the two fractions and print out the result. For example: a sample program run might look like this, Numerator One: 1 Denominator One: 2 Numerator Two: 2 Denominator Two: 5 The sum is 9/10 //remember if you have two fractions, the following formula should be used: a/b + c/d = (a*d +b*c) / b* d public class MyProgram { public static void main(String[] args) { //Ask the user for 4 numbers. (don't forget to import your Scanner class) //create your final numerator //create your final denominator //print out your result like the example above
