Question
Create a Java class using generics: ItemPair. Objects of this class hold a pair of two items that are the same type. For example, an ItemPair can hold two Integers or it could hold two Strings or it could hold two ArrayLists, etc. An ItemPair could not, however hold an Integer and a String. Write the following using generics: the class header instance data a constructor that takes both items in as parameters getters and setters for each item in the pair an equals method: two ItemPairs are the same (logically equivalent) if both items within the pair are the same (logically equivalent)Explanation / Answer
Please find my implementation.
Please met me know in case of any issue.
// class Header
public class ItemPair<T> {
// instance variables
private T first;
private T second;
// constructor
public ItemPair(T f, T s){
first = f;
second = s;
}
// getters and setters
public T getFirst() {
return first;
}
public void setFirst(T first) {
this.first = first;
}
public T getSecond() {
return second;
}
public void setSecond(T second) {
this.second = second;
}
@Override
public boolean equals(Object obj) {
return first.equals(second);
}
}
