reference type

A reference type is a data type that’s based on a class rather than on one of the primitive types that are built in to the Java language. The class can be a class that’s provided as part of the Java API class library or a class that you write yourself.

You can study this in the course. https://www.sololearn.com/Course/Java/

A reference type is something that is passed by reference. IE is an Object. int[] a = {6}; someMethod(a); void someMethod(int[] b){ b[0] = 2; // a becomes {2} }
