java arraylist of pairs
List<Pair<Integer,String>> pairList = new ArrayList<Pair<Integer,String>>();
public class Pair<Key,Value> {
private Key key;
private Value value;
public Pair(Key key, Value value){
this.key = key;
this.value = value;
}
public Key getKey(){ return this.key; }
public Value getValue(){ return this.value; }
public void setKey(Key key){ this.key = key; }
public void setValue(Value value){ this.value = value; }
}
//Notice that it doesn't have to be in a "Key-Value" fashion, it can be any 2 variables,
//For example Pair<X,Y>, getX(), getY(), etc.
Are there any code examples left?
