- In some cases, a class depends on itself. That is, an object of one class interactswith another object of the same class. To accomplish this, a method of the classmay accept as a parameter an object of the same class.The concat method of the String class is an example of this situation. Themethod is executed through one String object and is passed another String object as a parameter. Here is an example:str3 = str1.concat(str2);The String object executing the method (str1) appends its characters to thoseof the String passed as a parameter (str2). A new String object is returned asa result and stored as str3. Write java code to implement given conditionsThe Hal9000 has one constructor which takes a String parameter of a name of the crew member it is interacting with. It has methods: public String getName() which gets the name public void setName(String newName) which sets a new name public String greet() which returns a string consisting of "Greetings, name" where name is the name supplied in the constructor. public String reportStatus() which returns a string consisting of "All systems are operating normally, name" where name is the name supplied in the constructor. public String execute(String command) which returns a string consisting of "I am sorry, name. I can't " + command where name is the name supplied in the constructor and command is the parameter. Supply Javadoc for the constructor and all the methodsThe Hal9000 has one constructor which takes a String parameter of a name of the crew member it is interacting with. It has methods: public String getName() which gets the name public void setName(String newName) which sets a new name public String greet() which returns a string consisting of "Greetings, name" where name is the name supplied in the constructor. public String reportStatus() which returns a string consisting of "All systems are operating normally, name" where name is the name supplied in the constructor. public String execute(String command) which returns a string consisting of "I am sorry, name. I can't " + command where name is the name supplied in the constructor and command is the parameter.
- A class may occasionally be dependent upon itself. In other words, an object of one class engages in communication with an object of the same class. To do this, a method of the class can take an object of the same class as a parameter.An illustration of this scenario is the concat method of the String class. One String object calls the method, while another String object is supplied as an argument. Here's an illustration:str2 = str1.concat;The String object (str1) that executes the method adds its characters to the String (str2) that was supplied as a parameter. As a result, a fresh String object is produced and saved as str3. Write Java code to put the circumstances given into effect.In some circumstances, a class is reliant on itself. That is, one class's object interacts with another class's object. To accomplish this, a method of the class may accept an object of the same class as a parameter.The String class's concat function is an example of this situation. The method is called by one String object and receives another String object as an argument. Here's an illustration:str3 is equal to str1.concat(str2);The method's String object (str1) appends its characters to those of the String supplied as a parameter (str2). As a consequence, a new String object is returned and saved as str3. Create Java code to implement the conditions given.Implement the following class. Refer to the below notes for more details. SimCard phoneNumber: String internationalService: boolean minutes: int // default 0 costPerMinute: double + SimCard ( ) + SimCard ( newPhoneNumber: String, newInternationalService: boolean ) + getters and setters of phoneNumber, internationalService and costPerMinute + callLocal (duration: int): void + callInternational(duration: int): boolean + bill(): double o phoneNumber: private String representing the phone number. Default is "00-000000" o internationalService : private boolean indicating whether international calls are allowed or not. Default is false. o minutes: private int representing the number of minutes to be invoiced (added to the bill). Default is 0. o costPerMinute: private double representing the cost of 1 minute. This value should be positive. Default value is 0.2. Assume all the sim card has the same cost rate per minute. LS) The no-arg constructor that will create a new SimCard with the default…
- Define a class called StringFormatter. The purpose of an object of this class is to store a string variable (you may use the C++ string type or a char array). An object of this class can be created by calling a constructor that accepts one string argument. The string to be passed as argument will be a long line of text, such as “The world is indeed full of peril and in it there are many dark places. But still there is much that is fair. And though in all lands, love is now mingled with grief, it still grows, perhaps, the greater.” The object will also have a function called printRightAligned() which accepts one integer argument n. The value of the argument represents the maximum number of characters that can be displayed on a line. This function displays the string stored in the object’s attribute on the screen, right aligned and with no more than n characters per line. Similarly, there should be a function called printLeftAlgigned() which displays the text left aligned, again, with no…Write a class with a constructor that accepts a String object as its argument. The class should have a method that returns the number of b, c, d, f, g, h, and z in the string. Demonstrate the class in a program that asks the user to enter a string and returns the number of b, c, d, f, g, h, and z in the user string.You will create a couple of classes that could be used to create a Text Adventure game. The class will be called "Item" and will represent an item in the game that can be carried and used by a player (such as a weapon or a tool). The Item Class The Item class will have only one property: A string description. The Item class will have exactly 3 methods: There will be a default constructor that takes no parameters. This constructor will give a generic, default description of the Item. There will be a constructor that takes a string parameter, and it will initialize the Item's description based on the parameter. There will be a method called "print" that will print the Item's description to standard output. PLEASE MAKE SURE ITS POSSIBLE TO COMPILE WITH THIS CODE. THANKS. #include "Item.h" #include <iostream> #include <string> using namespace std; int main() { Item sword("Sword of Destiny"); Item potion("Healing Potion"); Item key("Key of Wisdom"); string name; cout…

Only allow a value between 0-200 (inclusive), otherwise print out a warning ("Illegal target heart rate") and leave targetHeartRate unchanged.In main(), prompt the user for two items and create two objects of the ItemToPurchase class. Before prompting for the second item, call scnr.nextLine(); to allow the user to input a new string.Ex: Item 1 Enter the item name: Chocolate Chips Enter the item price: 3 Enter the item quantity: 1 Item 2 Enter the item name: Bottled Water Enter the item price: 1 Enter the item quantity: 10
