💡 Frequently Asked Questions

Q: What is a POJO?

A: POJO stands for Plain Old Java Object. It represents standard Java data containers featuring private properties, default constructors, and public getter/setter methods, carrying no framework dependencies.

Q: How does the converter decide between Double and Integer?

A: It evaluates the value using standard JavaScript integer checks (`Number.isInteger()`). Whole numbers map to standard Java `Integer` classes, while floating decimals map to `Double` structures.
