Question

JAVA PROGRAMMING

In this final review lab from our intro course, use the Name class you created in the previous lab.

In this lab, create a Student class with the following class variable:

1. Student name: Name (Note: Name is a datatype)
2. Student Id: String

Create the getter and setter methods. In addition to these methods, create a toString() method, which overrides the object class toString() method. This override method prints the current value of any of this class object.

Complete the main() method below to test your project.

public static void main(String[] args)

List<Studcnt> myArrayList = new ArrayList<Student>();

---------------------------------------

--------------------------------------

--------------------------------------

for(Studnct students: myArrayList) {

System.out.println(students);

}

Here is name.java

public class Name
{
//Variable declaration
String firstName, lastName, middleName, fullName;

//Class constructor
public Name(String firstName, String lastName, String middleName) {
this.firstName = firstName;
this.lastName = lastName;
this.middleName = middleName;
this.fullName = firstName +" "+middleName+" "+lastName;
}

//getter method to get first name
public String getFirstName() {
return firstName;
}

//Setter Method
public void setFirstName(String firstName) {
this.firstName = firstName;
}

//getter method to get last name
public String getLastName() {
return lastName;
}

//Setter Method for last name
public void setLastName(String lastName) {
this.lastName = lastName;
}

//getter method to get middle name
public String getMiddleName() {
return middleName;
}

//Setter Method for middle name
public void setMiddleName(String middleName) {
this.middleName = middleName;
}

//getter method to get full name
public String getFullName() {
return fullName;
}

//Setter Method for full name
public void setFullName(String fullName) {
this.fullName = fullName;
}

//toString method
public String toString() {
return "Name{" +
"fullName='" + fullName + '\'' +
'}';
}
