Sorry to bother you again but I’m working on a class with a large number of variables (in C I would implement this as a struct). For debugging purposes I want to print (loop) over all variables inside this class. Unfortunatly I have no clue how to implement this.

Put me in the nasty boy room in case this is a stupid question.

A class needs to [`@Override`](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Override.html) the [**toString()**](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Object.html#toString()) method, so it can return a String w/ the current value of its fields. ☕

Here’s a link w/ an example for it: 🔗
