Write a java class named PhoneDirectory that contains the following data attributes and methods: private int numRecords - number of records in the array private PhoneRecordI [] data - array of PhoneRecord objects public PhoneDirectory () - constructor that should initialize memory for data array and numRecords value public void enterPhoneRecords(PhoneRecord new_record) - store a new phone record in the database public void findPhoneRecord(String key) - Search the database for records whose names begin with the search key. The user doesn't need to enter an entire name. This method will display all names that begin with the characters entered by the user. If the customer number is not in the array, the program will print that "the phone record does not exist"

When we use the Group-Object cmdlet, it will create this new property, which displays the number of objects in each grouping: Group of answer choices Number Count Entry Name

PLZ help with the following: True/False  In java it is possible to throw an exception, catch it, then re-throw that same exception if it is desired GUIs are windowing interfaces that handle user input and output. An interface can contain defined constants as well as method headings or instead of method headings. When a recursive call is encountered, computation is temporarily suspended; all of the information needed to continue the computation is saved and the recursive call is evaluated. Can you have a static method in a nonstatic inner class?

ReadInstructor. The class will: –  Create an array of instructor objects –  Read the instructors.txt file –  Create an Instructor object for each line of input and store the object in the array. –  After closing the file, it will print out a line for each instructor in the array.

Classes, Objects, Pointers and Dynamic Memory Program Description: This assignment you will need to create your own string class. For the name of the class, use your initials from your name.  The MYString objects will hold a cstring and allow it to be used and changed. We will be changing this class over the next couple programs, to be adding more features to it (and correcting some problems that the program has in this simple version). Your MYString class needs to be written using the .h and .cpp format. Inside the class we will have the following data members: Member Data Description char * str pointer to dynamic memory for storing the string int cap size of the memory that is available to be used(start with 20 char's and then double it whenever this is not enough) int end index of the end of the string (the '\0' char) The class will store the string in dynamic memory that is pointed to with the pointer. When you first create an MYString object you should…

Interval Difference: Please help me with this assertion error

void getVectorSize(int& size); void readData(vector<Highscore>& scores); void sortData(vector<Highscore>& scores); vector<Highscore>::iterator findLocationOfLargest( const vector<Highscore>::iterator startingLocation, const vector<Highscore>::iterator endingLocation); void displayData(const vector<Highscore>& scores); The size parameter from the given code won't be needed now, since a vector knows its own size. Notice that the findLocationOfLargest() function does not need the vector itself as a parameter, since you can access the vector using the provided iterator parameters. The name field in the struct must still be a c-string The focus of this assignment is to use iterators. You must use iterators wherever possible to access the vector. As a result, you must not use square brackets, the push_back() function, the at() function, etc. Also, the word "index" shouldn't appear in your code anywhere. You won't get full credit if…
