Functions That Return Multiple Values (record)

This lesson covers returning multiple values from a single function in Java using record, so you understand a function isn't limited to a single return value. It's for anyone searching "Java record multiple return values."

record is a relatively recent Java feature for bundling multiple values together. It's like "handing over one box holding both a minimum-value card and a maximum-value card."

The example defines a type for bundling data in one line, record MinMax(int min, int max) {}, and has the minMax() method return this MinMax type — returning the minimum and maximum together.

A common early mistake is not knowing a record automatically generates getters and an equals method for you. Doing the same thing with a regular class would take a lot of boilerplate code, but a record does it in one line.

In real projects, this is genuinely useful for things other languages would handle with a tuple or pair — Java lets you write it in a type-safe way with record.
