If you’re a Java developer who’s been longing for a more streamlined and intuitive way of querying databases, similar to the elegant LINQ constructs in C#, then you should check out the open-source library JPAStreamer. In this article, I will explore the powerful capabilities of this Java tool that brings a LINQ-like experience to your Hibernate queries.
Before diving deeper into JPAStreamer, I’ll describe some desirable properties of LINQ. A LINQ (Language Integrated Query) is a C# expression that can transform data from a variety of data sources, spanning from simple linear data structures to databases. Here is a basic example from the LINQ documentation that operates on an array of integers to find arbitrary scores greater than 80:
