Question

In Java Programming Complete the Code that remains to be implemented follow the guide lines here and finish what code remains name of program class Student.java

package course;

public class Student {

    private String firstName;
    private String lastName;
    private Address homeAddress;
    private Address schoolAddress;
    private double[] testScores;

        // Four parameter constructor
    public Student(String firstName, String lastName, Address homeAddress, Address schoolAddress) {
        // Call the seven parameter constructor. Pass zeros for the three grades
    }

        // Five parameter constructor
    public Student(String firstName, String lastName, Address homeAddress, Address schoolAddress, double[] testScores) {
        // Call the seven parameter constructor. Pass a testScores element to each grade
    }

        // Seven paramter constructor
    public Student(String firstName, String lastName, Address homeAddress, Address schoolAddress, double testScore1, double testScore2, double testScore3) {
        // Assign each of the first four parameters to the appropriate instance variable
                                
                // Instantiate a three element array of doubles for testScores
                
                // Assign the last three parameters to the appropriate testScores element

    }

        // Sets the value of testScores with testNumber - 1 to score
    public void setTestScore(int testNumber, double score) {

    }

        // Gets the value of testScores with testNumber - 1
    public double getTestScore(int testNumber) {

    }

        // Returns the average of the three test scores
    public double average() {

    }

    @Override
    public String toString()
    {
        String result;

        result = firstName + " " + lastName + "\n";
        result += "Home Address:\n" + homeAddress + "\n";
        result += "School Address:\n" + schoolAddress + "\n";
        result += "Test Scores: ";
        for (int i = 0; i < testScores.length - 1; i++) {
            result += testScores[i] + ", ";
        }
        result += testScores[testScores.length - 1] + "\n";
        result += "Average: " + average();

        return result;
    }
}

This is another class of the code called Address.java its to be ran with the following code above

package course;

public class Address {

    private String streetAddress;
    private String city;
    private String state;
    private long zipCode;

    public Address(String streetAddress, String city, String state, long zipCode) {
        this.streetAddress = streetAddress;
        this.city = city;
        this.state = state;
        this.zipCode = zipCode;
    }

    @Override
    public String toString() {
        String result;

        result = streetAddress + "\n";
        result += city + ", " + state + " " + zipCode;

        return result;
    }
}

Answer 1

Address.java

public class Address {
private String streetAddress;
private String city;
private String state;
private long zipCode;
  
public Address(String streetAddress, String city, String state, long zipCode)
{
this.streetAddress = streetAddress;
this.city = city;
this.state = state;
this.zipCode = zipCode;
}

@Override
public String toString()
{
String result;

result = streetAddress + "\n";
result += city + ", " + state + " " + zipCode;

return result;
}
}

Student.java

public class Student {
private String firstName;
private String lastName;
private Address homeAddress;
private Address schoolAddress;
private double[] testScores;
  
// Four parameter constructor
public Student(String firstName, String lastName, Address homeAddress, Address schoolAddress)
{

}
  
// Five parameter constructor
public Student(String firstName, String lastName, Address homeAddress, Address schoolAddress, double[] testScores)
{

}
  
// Seven paramter constructor
public Student(String firstName, String lastName, Address homeAddress,
Address schoolAddress, double testScore1, double testScore2, double testScore3)
{
this.firstName = firstName;
this.lastName = lastName;
this.homeAddress = homeAddress;
this.schoolAddress = schoolAddress;
  
this.testScores = new double[3];
this.testScores[0] = testScore1;
this.testScores[1] = testScore2;
this.testScores[2] = testScore3;
}
  
// Sets the value of testScores with testNumber - 1 to score
public void setTestScore(int testNumber, double score)
{
this.testScores[testNumber - 1] = score;
}

// Gets the value of testScores with testNumber - 1
public double getTestScore(int testNumber)
{
return this.testScores[testNumber - 1];
}

// Returns the average of the three test scores
public double average()
{
double total = 0.0;
for(int i = 0; i < 3; i++)
{
total += this.testScores[i];
}
return(total / 3.00);
}

@Override
public String toString()
{
String result;

result = firstName + " " + lastName + "\n";
result += "Home Address:\n" + homeAddress + "\n";
result += "School Address:\n" + schoolAddress + "\n";
result += "Test Scores: ";
for (int i = 0; i < testScores.length - 1; i++) {
result += testScores[i] + ", ";
}
result += testScores[testScores.length - 1] + "\n";
result += "Average: " + average();

return result;
}
}

Tester.java

public class Tester {
  
public static void main(String[] args)
{
Address homeAddress = new Address("7554", "Depew", "New York", 14043);
Address schoolAddress = new Address("7189", "Parsippany", "New Jersey", 07054);
double testScores[] = new double[3];
testScores[0] = 56.50;
testScores[1] = 78;
testScores[2] = 88.50;
  
Student student = new Student("John", "Doe", homeAddress, schoolAddress, testScores);
  
System.out.println(student.toString());
}
}
