Expert Solution
Step 1
Hi... Please check below java code.
Mailbox.java
import java.util.List;
public class Mailbox {
private List<Message> all;
private int numOfMessages;
public List<Message> getAll() {
return all;
}
public void setAll(List<Message> all) {
this.all = all;
}
public int getNumOfMessages() {
return numOfMessages;
}
public void setNumOfMessages(int numOfMessages) {
this.numOfMessages = numOfMessages;
}
public Mailbox(List<Message> all, int numOfMessages) {
super();
this.all = all;
this.numOfMessages = numOfMessages;
}
public Message getMessage(int i){
return all.get(i-1);
}
public void removeMessages(int i){
all.remove(i-1);
}
public void printAllMessages(){
for(Message m:all){
System.out.println(m.getMessage());
}
}
}
Message.java
public class Message {
private String message;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public Message(String message) {
super();
this.message = message;
}
}
