Need Java Code for this assignment I am using Eclipse IDE…

Solution:

package com.student;

import java.util.Scanner;

public class DriverExam {
String correctAnswer[] = { “B”, “D”, “A”, “A”, “C”, “A”, “B”, “A”, “C”, “D”, “B”, “C”, “D”, “A”, “D”, “C”, “C”, “B”,
“D”, “A” };

String studentCorrectAnswer[] = new String[20];

public boolean passed() {
return totalCorrect() >= 15 ? true : false;
}

public int totalCorrect() {
int totalCorrectAnswer = 0;
for (int i = 0; i < correctAnswer.length; i++) {
if (correctAnswer[i].equals(studentCorrectAnswer[i])) {
totalCorrectAnswer++;
}
}
return totalCorrectAnswer;
}

public int totalIncorrect() {
int totalIncorrectCorrectAnswer = 0;
for (int i = 0; i < correctAnswer.length; i++) {
// check if answered not matched
if (!(correctAnswer[i].equals(studentCorrectAnswer[i]))) {
if (studentCorrectAnswer[i] != null) {
totalIncorrectCorrectAnswer++;
}
}
}
return totalIncorrectCorrectAnswer;
}

public int totalQuestionMissed() {
int totalQuestionMissed = 0;
for (int i = 0; i < correctAnswer.length; i++) {
// check if answered not matched, if not matched then might be the
// index value is null if null then its not attempted by student
if (!(correctAnswer[i].equals(studentCorrectAnswer[i]))) {
if (studentCorrectAnswer[i] == null) {
totalQuestionMissed++;
}
}
}
return totalQuestionMissed;
}

public static void main(String[] args) {
DriverExam driverExam = new DriverExam();
Scanner in = new Scanner(System.in);
while (true) {
System.out.println(“Do you want to continue answer Y or N”);
String iscontinue = in.nextLine();
if (“Y”.equalsIgnoreCase(iscontinue)) {

} else if (“N”.equalsIgnoreCase(iscontinue)) {
break;
} else {
System.out.println(“please provide input in Y or N in order to continue or pause your answering”);
continue;
}
System.out.println(“Please Enter your Question Number”);
String s1 = in.nextLine();
int index = 0;
try {
index = Integer.parseInt(s1);
index = index – 1;
if (index > driverExam.studentCorrectAnswer.length – 1) {
System.out.println(“please enter value less than 21”);
continue;
}
} catch (Exception e) {
System.out.println(“please provide question number in integer value”);
continue;
}
System.out.println(“Please Enter Your Answer Now”);
String answer = in.nextLine();
if (“A”.equals(answer) || “B”.equals(answer) || “C”.equals(answer) || “D”.equals(answer)) {
driverExam.studentCorrectAnswer[index] = answer;
} else {
System.out.println(“Please enter option in A B C D only”);
}

}
System.out.println(“is passed=”+driverExam.passed());
System.out.println(“total correct answer=” + driverExam.totalCorrect());
System.out.println(“total incorrect answer=” + driverExam.totalIncorrect());
System.out.println(“total missed question=” + driverExam.totalQuestionMissed());
}

}
