Answer to Question #204710 in Java | JSP | JSF for 20200073

Question

you are required to create a console application that will capture the amount of votes that a student representative has received during the annual student body elections. the application must capture the student names and the amount of votes. in your solution, include a class called votes. the class must include the following:

*variables to store the student name and votes received.

* variables to store the total and average votes.

*use a constructor or method to set the variables.

* two methods to calculate the total and average votes.

* a method to print the report. the report must display good or poor voting attendance. if the total amount of student votes is greater than 150, display good voting attendance, otherwise display poor voting attendance

Answer 1

		this.totalVotes=0;
	}


	// use a constructor or method to set the variables.
	public void addStudentName(String name) {
		this.studentNames.add(name);
	}


	public void addStudentVotesReceived(int votesReceived) {
		this.votesReceived.add(votesReceived);
	}


	// two methods to calculate the total and average votes.
