Question
I have this code below, but I don't understand why it is not working. What am I doing wrong? I keep recieving the message "Team cannot be resolved to a type". I have no clue what to do in this code.

Explanation / Answer
Hi Friend, You program is using Team Object.
I have defined Team object.
You can modify according to your need.
Please add this file along with your program. It will compile
class Team implements Comparable<Team>{
private String name;
int rank;
private String comment;
public Team(String name, int rank, String comment) {
super();
this.name = name;
this.rank = rank;
this.comment = comment;
}
public String getName() {
return name;
}
public int getRank() {
return rank;
}
public String getComment() {
return comment;
}
public void setName(String name) {
this.name = name;
}
public void setRank(int rank) {
this.rank = rank;
}
public void setComment(String comment) {
this.comment = comment;
}
@Override
public int compareTo(Team o) {
if(rank > o.rank)
return 1;
else if(rank < o.rank)
return -1;
else
return 0;
}
}
