I am having trouble with this:
Implement the convertString method based on its specification. Here are some things that can help:
the Character class has some utility methods to determine if a character is uppercase, lowercase, or a digit (numeral)
the String class has a method to get the character at a specific position (called the index). Find that method and use it.
make use of the convert methods you already have!convertString Specification: /** * Converts the letters and numerals in the given string * to their circled counterparts. All other characters * are unchanged. * * @precondition text != null * @postcondition none * * @param text the text to convert * @return a modified version of text, with all letters and numerals * circled. */My code:
public class CircleStrings {
/** * Converts the letters and numerals in the given string * to their circled counterparts. All other characters * are unchanged. * *…
Does every class have a copy constructor? How is a copy constructor named? Can it be overloaded? Can you redefine a copy constructor? How do you invoke one?
Help, I making a elevator simulator, I need help in writing code in the Elevator class and it's polymorphism class. I am not sure what to do next. Any help is appreciated.
There are 4 types of passengers in the system:Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements.VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators.

- 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.

- Novice: How can i access a main class objects from outside the function? / Better Alternative? If i have 4 Student objects how can i print the information for the specific object given one parameter about the class, like the students Idnumber. What i came up with was making a checkId void function that takes the user input and runs an if else chain checking if the Id belongs to student 1-4 then printing the details of that classes object with the void function print. ideally i would want the if-else chain in the checkId function to call the print( student1-4) class object but im not sure how to properly do that. i dont think this is the best way to go about it, if you have any recommendations or alternatives please help me out.arrow_forwardUSING C++ Random Number Guesser Write a derived class of the NumberGuesser class named RandomNumberGuesser.

Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.arrow_forward
