is it possible to work with pairs in online ide’s in java without using maps because maps doesn’t works in every matter when dealing with pairs . Is there something like the pair in java just like in c++?
In java collections there is no such class or interface like pairs of c++ stl. But we can create a custom class of pairs and then use it with any generic collection.
Create custom class:
class Pair{
int first;
int second;
}

There’s no built-in Pair class in JAVA.
You can create custom class.
`
class Pair<E,V> {
E first;
V second;
Pair(E e, V v) {
this.first = e;
this.second = v;
}
}
`
This generic class can be used for any kind of data types as well as for your custom defined classes.
