Consider the following class definition.public class Party{private int numofPeople;private double volumeOfMusic;/* missing constructor * /The following statement appears in a method in a class other than Party.It is intended to create a new Party object p with its attributes set to 10 and 5.0.Party pnew Party(10, 5.0);Which of the following can be used to replace / * missing constructor */so that the object p is correctly created?a. public Party(int numOfPeople, double volumeOfMusic){numofPeople = this.numOfPeople;volumeOfMusic = this.volumeOfMusic;}b. public Party(int numofPeople, double volumeOfMusic){this.numOfPeople = numOfPeople;this.volumeOfMusic = volumeOfMusic;c. public Party(int first, double second){numOfPeople = 10;volumeOfMusic = 5.0;}d. public Party(int first, double second){first = numofPeople;second = volumeOfMusic;}e. None of the above

Please find the answer and the sample program in the below step. The program is written in Java.

public class Party { private int numofPeople; private double volumeOfMusic; /* missing constructor */ The following statement appears in a method in a class other than Party. t is intended to create a new Party object p with its attributes set to 10 and 5.0.

public class Party { private int numofPeople; private double volumeOfMusic; /* missing constructor */ The following statement appears in a method in a class other than Party. t is intended to create a new Party object p with its attributes set to 10 and 5.0.

OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Question

Consider the following class definition.
public class Party
{
private int numofPeople;
private double volumeOfMusic;
/* missing constructor * /
The following statement appears in a method in a class other than Party.
It is intended to create a new Party object p with its attributes set to 10 and 5.0.
Party p
new Party(10, 5.0);
Which of the following can be used to replace / * missing constructor */
so that the object p is correctly created?
a. public Party(int numOfPeople, double volumeOfMusic)
{
numofPeople = this.numOfPeople;
volumeOfMusic = this.volumeOfMusic;
}
b. public Party(int numofPeople, double volumeOfMusic)
{
this.numOfPeople = numOfPeople;
this.volumeOfMusic = volumeOfMusic;
c. public Party(int first, double second)
{
numOfPeople = 10;
volumeOfMusic = 5.0;
}
d. public Party(int first, double second)
{
first = numofPeople;
second = volumeOfMusic;
}
e. None of the above
