The result: A banking system with near-zero critical bugs, despite changing requirements every two weeks.
Two developers work at one workstation. One writes the Java code (driver), the other reviews each line (navigator). This reduces bugs, spreads Java knowledge, and improves design quality—especially in complex J2EE or Spring applications.
XP is famous (or infamous) for Pair Programming—two developers working at one workstation. Critics argue it cuts productivity in half; proponents argue it doubles code quality.

In the modern dev landscape, whether you are using Spring Boot, Quarkus, or Micronaut, you are standing on the shoulders of this partnership. The compiler is your safety net, the unit test is your compass, and the code is the conversation. That is the legacy of Java XP.
Whether you are an experienced developer ("XP" as in Experience) or an agile practitioner, mastering the Java ecosystem requires a deep dive into its core features:
The Navigator doesn't have to mentally parse syntax errors; the IDE handles that. Instead, the Navigator can focus on the strategic design: "Are we following the Single Responsibility Principle? Should this be an Interface?" The result: A banking system with near-zero critical
XP introduced the concept of Test-Driven Development (TDD): write a failing test, write the code to pass it, refactor.
The foundation of all Java development, covering basic syntax, collections, and multithreading.

In the context of enterprise web development, specifically within , "xp" is the default prefix for XPages library tags.
Java is often criticized as “anti-agile” due to boilerplate and compilation times. However, Java XP leverages Java’s strengths:
