How Can I Effectively Replace C 's `Pair` in Java?

Replacing C Pair in Java

Java lacks a direct equivalent to the C Pair construct, raising questions about its absence and suitable alternatives.

Arguments for Omitting Pair in Java

Hunter Gratzner argues against introducing Pair into Java, citing its ambiguous semantics. Without explicit meaning, "first" and "second" labels become arbitrary and fail to convey the intended relationship between the values.

Alternatives to Pair

Instead of relying on a generic Pair class, it's recommended to define specialized classes for specific applications, such as Position(x,y), Range(begin,end), or Entry(key,value). These dedicated classes provide clear semantic context and enhance code readability.

Legacy Solution

For applications compatible with Java 1.6, the AbstractMap.SimpleEntry class can serve as a rudimentary Pair equivalent. However, its syntax is less straightforward than a dedicated Pair implementation.
