FacebookStatus.java
========

public class FacebookStatus {
private String status;
private int nrOfLikes;

public FacebookStatus(String status){
this.status = status;
this.nrOfLikes = 0;
}

public FacebookStatus(String status, int nrOfLikes){
this.status = status;
this.nrOfLikes = nrOfLikes;
}

public String toString(){
return "Status: " + status + "[No. of likes: " + nrOfLikes + "]";
}
}

FacebookUser.java
======
public class FacebookUser {
private String firstName;
private String lastName;
private String userName;
private FacebookStatus[] statuses;

public FacebookUser(String fname, String lname, String uname){
firstName = fname;
lastName = lname;
userName = uname;
}

public String toString(){
String s = "Name: " + lastName +", " + firstName + ", Username: " + userName +" ";
if(statuses != null)
{
for(int i = 0; i < statuses.length; i++)
{
s += statuses[i] + " ";
}
}
return s;
}

public void add(FacebookStatus fbStatus){
if(statuses == null)
statuses = new FacebookStatus[1];

else{
FacebookStatus[] temp = new FacebookStatus[statuses.length + 1];
for(int i = 0; i < statuses.length; i++)
temp[i] = statuses[i];

statuses = temp;
}

int len = statuses.length;
statuses[len-1] = fbStatus;
}

}

FacebookApplication.java
---------

public class FacebookApplication {
public static void main(String[] args) {
FacebookUser user = new FacebookUser("Jonn", "Smith", "jsmith");

System.out.println("Before adding the status, the user is " + user);

FacebookStatus s1 = new FacebookStatus(" I'm not lazy, I'm on energy saving mode :D", 10);
FacebookStatus s2 = new FacebookStatus("Not always 'Available' try your luck!");
FacebookStatus s3 = new FacebookStatus("Sometimes you succeed... and other times you learn.", 20);
FacebookStatus s4 = new FacebookStatus("Behind every successful man is a surprised woman", 5);
FacebookStatus s5 = new FacebookStatus("Silent people have the loudest minds.");
user.add(s1);
user.add(s2);
user.add(s3);
user.add(s4);
user.add(s5);

System.out.println("After adding the status, the user is " + user);

}
}
