Question

Consider the following instance variables and method from a class:
private String descriptor;
public String makeSentence(int quant, boolean sign)
{
Strings = "Object is ";
if (!sign)
{
s += "not";
}
for (int i = 0; i <quant; i++)
{
s += "very";
}
return s + descriptor;
}
Suppose an object of this class is initialized so the value of descriptor is "regular". What would be returned by
the call makeSentence(3, false) made on this object?

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",…
Create a fee invoice application for students attending Valence College, a college in the State of Florida. There are two types of students: graduate and undergraduate. Out-of-state undergraduate students pay twice the tuition of Florida-resident undergraduate students (all students pay the same health and id fees). A graduate student is either a PhD or a MS student. PhD students don't take any courses, but each has an advisor and a research subject. Each Ms and Phd student must be a teaching assistant for one undergraduate course. MS students can only take graduate courses. A course with a Course Number (crn) less than 5000 is considered an undergraduate course, and courses with a 5000 crn or higher are graduate courses.
