Question

Modify the objectstudent JAVA program to add a private variable zipcode, you must also add setters and getter methods for the new variable and modify the toString method. The objectstudent program is in this weeks module, you can give it a default value of 19090.

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 na

me is " + s1.getname());

}

}

class Student
{
    private int id;
    private String name;
    private int zipcode;

    public Student()
    {
        id = 8;
        name = "John";
        zipcode = 19090;
    }

    public int getid()
    {
        return id;
    }

    public String getname()
    {
        return name;
    }

    public int getZipcode()
    {
        return zipcode;
    }

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

    public void setname(String newname)
    {
        name = newname;
    }

    public void setZipcode(int zipcode) 
    {
        this.zipcode = zipcode;
    }

    public String toString()
    {
        String result = Integer.toString(id)+" "+name+" "+zipcode;
        return result;
    }
}
