Create a public static Boolean field named debugMode and initialize debugMode with true. Ex: If the input is Gus Ben Ron, then the output is: Debug mode ON: Client's constructor called Debug mode ON: Client's constructor called Debug mode ON: Client's constructor called Client is Gus. Client is Ben. Client is Ron. Note: Debugging is commonly done with output messages. A static Boolean field like debugMode controls whether the debugging message is to be shown or hidden. 1 public class Client { 2 3 456789 10 11 12 13 14 15 16 17 18 /* Your code goes here */ Client.java NewClients.java private String name; public Client(String newName) { if (debugMode) { System.out.println("Debug mode ON: Client's constructor called"); } name = newName; } public void print() { if (debugMode) { System.out.println("Debug mode ON: print () called"); } System.out.println("Client is + name

Which of the following statements are correct about the given code snippet? class A: def __init__(self, i = 0): self.i = i class B(A): def __init__(self, j = 0): self.j = j def main(): b = B() print(b.i) print(b.j) Group of answer choices Class B inherits A, but the attribute “i” in A is not inherited. Class B inherits A, thus automatically inherits all attributes in A. When you create an object of B, you have to pass an argument such as B(5). The attribute “j” cannot be accessed by object b. How many except statements can a try-except block have? Group of answer choices zero one more than one more than zero
The Article class has a default constructor with no parameters. Define a public overloaded constructor that takes two string parameters and initializes the article's title and author with the strings. Ex: If the input is Airport Hall, then the output is: Article: Unspecified, Undefined Article: Airport, Hall Article.java public class Article { privateStringtitle; privateStringauthor; publicArticle() { // Default constructor title="Unspecified"; author="Undefined"; } /* Your code goes here */ publicvoidprint() { System.out.println("Article: "+title+", "+author); } } Archive.java
JAVA PROGRAM For this program, you are tasked to implement the Beverage class which has the following private properties: name - a string value volume - this is an integer number which represents its current remaining volume in mL isChilled - this is a boolean field which is set to true if the drink is chilled It should have the following methods: isEmpty() - returns true if the volume is already 0 {toString() - returns the details of the object in the following format: {name} ({volume}mL) {"is still chilled" | "is not chilled anymore"}.Example returned strings: Beer (249mL) is still chilled Water (500mL) is not chilled anymore A constructor method with the following signature: public Beverage(name, volume, isChilled) Getter methods for all the 3 properties. Then, create two final subclasses that inherit from this Beverage class. The first one is the Water class which has the additional private property, type, which is a String and can only be either "Purified", "Regular",…
use java to write code and please use treeset as mentioned in the question Create a class Customer with below attributes: int - id String - name String - dob double - salary String - email int - age Make all the attributes private.Create corresponding getters and setters. Create a constructor which takes all parameters in the above sequence. The constructor should set the value of attributes to parameter values inside the constructor.

This method has to take a list of Customer objects and return a TreeSet of Customer objects sorted based on id. Call the above method from the main method
The 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.

True or False: If methodA() has an equals() method that overrides the one in the Object class, then in our JUnit test for methodA(), assertEquals() will use the version of equals() in methodA().
Below is the code for a Time class that has both an equals method and a hashCode method; however, the body of the hashCode method is missing. In the text box, write the code you would put inside the body of the hashCode method. Remember that a hashCode with no collisions is better than a hashCode that has collisions and a hashCode with no gaps in the values is better than a hashCode that has gaps. public class Time { private int hour; // A number between 1 and 12 private int min; // A number between 0 and 59 private boolean pm; // True if the time is pm. public Time(int hour, int min, boolean pm) { this.hour = hour; this .min = min; this.pm = pm; } public int getHour() { return hour; } public int getMin() { return min; } public boolean isPM() { return pm == true; } public boolean isAM() { return pm == false; } public boolean equals(Object obj) { if (this == obj) return true; if (obj ==…
