I need to Modify the objectstudent JAVA program to add a private variable zipcode, you must also add setters and getter method

Question

class Student

{

private int id;

private String name;

public Student()

{

id = 8;

name = "John";

}

public int getid()

{

return id;

}

public String getname()

{

return name;

}

public void setid(int newid)

{

id = newid;

}

public void setname(String newname)

{

name = newname;

}

public String toString()

{

String result = Integer.toString(id)+" "+name;

return result;

}

}

class TestStudent1

{

public static void main(String args[])

{Student s0=new Student();

System.out.println(s0);

Student s1=new Student();

s1.setid(312);

s1.setname("Patrick");

System.out.println("ID is " + s1.getid());

System.out.println("The student name is " + s1.getname());

}

}

Answer 1

class Student

{

private int id;

private String name;

private String zipCode;

//constructor

public Student(int ID, String Name, String zip)

{

this.id = ID;

this.name = new String(Name);

this.zipCode = new String(zip);

}

//copy constructor

public Student (Student student)

{

this.id = student.getID();

this.name = new String(student.getName());

this.zipCode = new String(student.getZipCode());

}

//use camelCase for your getter and setter names to make them

//more readable... always returns COPIES of the strings, so

//no one else can change them !!

public int getID() { return id; }

public String getName() { return new String(name); }

public String getZipCode() { return new String(zipCode); }

public void setID(int newid) { id = newid; }

public void setName(String newname) { name = new String(newname); }

public void setZipCode(String zip) { zipCode = new String(zip); }

@Override public String toString()

{

return (

new String(

"Id=" + Integer.toString(id)+" Name=>" + name + "< zipCode =>" + zipCode + "<"

)

);

}

public String SerializeToCSV() //comma separted values

{

return(

new String(

this.id + "," + this.name+ "," + this.zipCode + "\n"

)

);

}

public void Display(String debugMsg)

{

if (debugMsg!=null)

{

System.out.println("*************************************************");

System.out.println(debugMsg);

}

System.out.println("*********************************************");

System.out.println(" ID = " + this.id);

System.out.println(" name =>"+ this.name+"<");

System.out.println(" zip code = >"+ this.zipCode +"<");

System.out.println(" Serialized as String :>"+this.toString() + "<");

System.out.println(" Serialized as CSV String :>" + this.SerializeToCSV() + "<");

}

public static void main(String args[])

{

Student student1 = new Student (8,"John","44526");

Student student2 = new Student (312,"Patrick","32824");

//here is YOUR student record

int yourID=123; // set your id # here !!!

String yourZipCode = new String("?????-????"); // set your zip code here inside the double quotes !!!

Student student3 = new Student (yourID,"Kevin J.",yourZipCode);

//Mick and Mack and twins!!!

Student studentTwin1 = new Student(111,"Mick","43210");

Student studentTwin2 = new Student(studentTwin1); //calls the copy constructor

studentTwin2.setName("Mack");

studentTwin2.setID(112);

student1.Display("1st studnet object");

student2.Display("my student object");

student3.Display("your student object");

studentTwin1.Display("Twin #1");

studentTwin2.Display("Twin #2");

}

}
