How can I work out these questions?? Would really appreciate your help. things like looking for things in the Hashmap.
• isRally - takes a String containing a rally code as a parameter and returns true if it represents a rally object stored in the allRallies collection, and false otherwise.
• findRally - takes one String parameter containing the rally code and returns the corresponding Rally object, or null if the rally is not in allRallies.
• findRider - takes one int parameter representing the rider ID and returns the corresponding Rider, or null if the rider is not in allRiders.
private HashMap<String, Rally> allRallies = new HashMap<String, Rally>();
private ArrayList<Rider> Allriders = new ArrayList<Rider>();
private ArrayList<Rally> allvenues = new ArrayList<Rally>();
public Branch()
{
}
public boolean isRally(Rally keys)
{
// for(String keys : AllRallies.getCode())
// if(into.grtCount() <= 0)
// {
// return true ;
// }
// return false;
}
