We saw in class the Conditional Identity, namely that p → q ≡ ¬p∨q. We might wonder then why it is necessary to even include → as an operator since it’s redundant. Well we include it because it is simpler to write and it is a very common operation in logic. However, this then might lead to the question of how many of our operators are redundant? Without → then we are down to 4 operators: ¬, ∧, ∨, and ⊕. Can we show we need even fewer?

7. the cullerton park district holds a mini-olympics each summer. create a class named participant with fields for a name, age, and street address. include a constructor that assigns parameter values to each field and a tostring() method that returns a string containing all the values. also include an equals() method that determines two participants are equal if they have the same values in all three fields. create an application with two arrays of at least eight participants each—one holds participants in the mini-marathon, and the other holds participants in the diving competition. prompt the user for participant values. after the data values are entered, display values for participants who are in both events. save the files as participant.java and twoeventparticipants.java.
