For this task, save your work in Diamond.javaWrite a public class Diamond. Inside it, implement a functionpublic static void printDiamond (int k)that takes a nonnegative integer k denoting the size of the diamond and prints to the screen (usingSystem.out) a diamond of size k.A diamond of size k contains a total of 2k - 1 lines, where every line contains a total of 2k +1characters (each character is either a # or a *). A few examples are given in Figure 1 for you to discoverthe pattern. Be warned that this task is not identical to a similar task you saw in Intro to Programming.Homework 12Data Struct.Specific Implementation Details: Your code can only use for-loops. You will print using either print,println, or print f. You may wish to learn about the repeat method, available for the String datatype.

Use java to write a test program that creates an array of 4 Worker objects. For each object, display theworker’s information and also his/her monthly salary. Both the HourlyWorker and SalariedWorker classes are required to provide anoperation to calculate the worker’s monthly salary. The salaried worker is paid a monthly basic salary + allowance.An hourly worker is paid payRate * hoursWorked
Define an iterator class named FibonacciIteratorfor iterating Fibonacci numbers. The constructor takes an argumentthat specifies the limit of the maximum Fibonacci number. For example, new FibonacciIterator(23302) creates an iterator that iterates Fibonacci numbersless than or equal to 23302. Write a test program that uses this iterator todisplay all Fibonacci numbers less than or equal to 120000.

write a java method with followin instraction : Write a method called prioritizeQueue to give priority for vaccination for elderly persons. The method is to be in a class called VaccinationQueue and has two parameters q1 and q2 type ArrayQueue. The q1 and q2 data are of type Integer. Assume that initially q1 is not empty and q2 is empty. The method will insert from q1 those elements towards the beginning of the queue (front) q2 whose data is greater than or equal to 45 and will insert those elements whose data is less than 45 and greater than or equal to 18 towards the end (rear) of q2. Any data item less than 18 of q1 will not be inserted in q2. It returns the number of elements added to q2. Class ArrayQueue and all its methods including iterator are available for use. You can also create temporary queues. You are not allowed to use arrays or any other data structure. Example: Before method call: front rear q1: 14 25 50…
Write a class that represents a player in a game. The player should have a name, password,experience points, an inventory array of four strings, and a location x,y. Your class shouldhave mutator and accessor methods for all variables. For example: setName(), getName(). Itshould have a suitable display method. Mutators and accessors should be public but allvariables should be private. To implement get inventory, use string * getInv(); Use the scoperesolution operator to implement larger methods such as display(). Use in class methods forshorter methods such as setName(), getName(). (in C++)Example:void setName(string name){this->name = name;}string *getInv();...string* player::getInv(){return inventory;}Note that in the above method setName “this->” is required for disambiguation. If writtenvoid setName(string n){name = n;}“this->” is not required.Write a test program that creates three players and displays them.Example Output:This program generates three player objects and…

Write a Java class that would match a string. The class has method match with String as a return type. It accepts two inputs: the phrase/sentence string (text) and the pattern string (word). This method finds the first (or all) instances of the pattern in the text and changes that word in all uppercase and return the new phrase. Method countOccurence accepts a phrase/sentence and a pattern string and returns its number of occurrences. Add a main method that will allow the user to input the phrase/sentence and pattern. Call method match and countOccurence. See test case below. Sample Input: Text string: You will always have my love, my love, for the love I love is as lovely as love itself. Pattern string: love Output: New text: You will always have my LOVE, my LOVE, for the LOVE I LOVE is as lovely as LOVE itself. Number of occurrence: 5 For example: Input Result You will always have my love, my love, for the love I love is as lovely as love itself. love New text: You…
