Help with war game

Question

I am learning java and was looking at this program I don't understand what is wrong with it, I am getting an error that says something about the compareTo cannot be found and variable cannot be found.
class Card implements Comparable
Card(int r, int s)
rank = r;
suit = s;
int getRank()
return rank;
int getSuit()
return suit;
public int compareTo(Object ob)
Card other = (Card)ob;
int thisRank = this.getRank();
int otherRank = other.getRank();
if (thisRank == 1) thisRank = 14; // make aces high
if (otherRank == 1) otherRank = 14;
return thisRank - otherRank;
public boolean equals(Object ob)
if (ob instanceof Card)
Card other = (Card)ob;
return value==other.value && suit==other.suit;
else return false;
public String toString()
String val;
String [] suitList =
{ "", "Clubs", "Diamonds", "Hearts", "Spades" };
if (rank == 1) val = "Ace";
else if (rank == 11) val = "Jack";
else if (rank == 12) val = "Queen";
else if (rank == 13) val = "King";
else val = String.valueOf(rank); // int to String

Answer 1

return value==other.value && suit==other.suit;I don't see a variable named value defined anywhere either. Do you? I do see rank and suit variables though.
