- Overloading is achieved when two or more methods in the same class have the sameTrue or False a. If you do not write a constructor for a class, java will supply a default constructor. b. Java does not allow constructors to be overloaded. Abstract methods must have a void return type. d. All classes have a default equals (Object) method even if their programmer didn't write one for it. You can override a static method defined in a superclass. A method can have at most one return statement. g. A method cannot return a Wrapper class reference. h. The reserved word super can be used to access a constructor in a parent class. i. Object is an abstract class. e. f.True or false?(a) You can override a nonprivate method defined in a superclass.(b) You can override a private method defined in a superclass.(c) You can override the initializer defined in a superclass. (d) When constructing an object from a subclass, its superclass’s initializer is automatically invoked.

- Design/code/test a Java program containing an abstract the class absWelcome. This class should contain: 1. A public abstract void method (you name it) that is empty 2. A public regular method (you name it) that prints "Welcome to " Next, create a subclass clsHello that extends absWelcome. This class should contain: • A public regular method (you name it) that prints "Java Programming" Finally, inside the Main class create an object (you name it) from the clsHello class. Use this new object reference to: 1. Output "Welcome to " from the abstract class 2. Output "Java Programming" from the subclass Your output should resemble that shown below >sh -c javac -classpath -type f-name '*.java') java -classpath :targe Welcome to Java ProgrammingAnswer all of the following questions as they are connected altogether: 3. How can we access the class members?4. Explain static members and static methods.5. Explain method overloading with example.Define a new "Exam" class that manages the exam name (string) and its score (integer). For example, an exam can have - "Midterm Exam", 100 - "Final Exam", 50 The class must not provide the default constructor. It must require the exam name and score in order to initialize the Exam object. The class must provide only the following methods (no more and no less): - isPerfect method that returns true if the score is exactly 100 and false otherwise. - isPassing method that returns true if the score is equal or greater than 70 and false otherwise. - toString method must return all the exam information including the result of the exam as a string in the following format: EXAM(<name>) SCORE(<score>) RESULT(Pass/Fail) such asEXAM(Midterm Exam) SCORE(100) RESULT(Pass) EXAM(Final Exam) SCORE(50) RESULT(Fail) "Pass" means the score is greater or equal 70. "Fail" is whenever the score is below 70. - isGreater method that compares with another Exam object and return true if the score…
