Singly Linked List - Java Implementation

------------------------------File 1: Employee.java ----------------------------------

package org.Solutions;

System.out.println("DOB :"+this.dateOfBirth);
System.out.println("ZipCode :"+this.empZipCode);
System.out.println("----------------------END OF RECORD---------------------------------------------------");
}
}


------------------------------File 2: Node.java ----------------------------------
package org.Solutions;

//Singly linked list implementation
public class Node {
Employee emp;
Node next=null;

public Node(Employee emp){
this.emp=emp;
}

public void add(Employee emp){
Node newNode=new Node(emp);
Node nextNode=this;
while(nextNode.next != null){
nextNode=nextNode.next;
}
nextNode.next=newNode;
}

public void traverse(){
Node n=this;
while(n!=null){
n.emp.printAll();
n=n.next;
}
}

}

------------------------------File 3: MainClass.java ----------------------------------

package org.Solutions;

public class MainClass {

public static void main(String[] args) {
Node empNode=new Node(new Employee("First Name","Last Name","19800101","123-4567"));
empNode.add(new Employee("First Name","Last Name","19800201","123-4568"));
empNode.add(new Employee("First Name","Last Name","19800301","123-4569"));
empNode.add(new Employee("First Name","Last Name","19800401","123-4566"));
empNode.add(new Employee("First Name","Last Name","19800501","123-4566"));
empNode.traverse();
}

}
