I am trying to make a java program with three threads. two representing client bob and Alice. a third thread representing a mail server. make Alice check their mailbox every 5 second if their is a mail form bob, Alice should send one back and bob should do the same thing. Pre-load Alice's mailbox with one mail from Bob. For the next minute or so, Alice should check for mail every 5 seconds and Bob should check for mail every 3 seconds. If they receive a mail, they should send one back. The body of the first mail should say "Hello", the body of the second mail should say "Hello Hello", and so on. Design a Mail class that has fields From, To, Date, Body. here is what I have but Im lost
