What are reference data types in Java?
Reference data types in Java are data types that store references to objects in memory rather than the actual data itself. These data types include classes, interfaces, arrays, and other reference types. When a reference data type is created, it only stores the memory address of the object it refers to, allowing multiple variables to refer to the same object. This is in contrast to primitive data types, which directly store the actual data values.

Is Java object assignment a reference or a value?
In Java, object assignment is a reference. When an object is assigned to a variable, the variable holds a reference to the memory location where the object is stored, rather than the actual object itself. This means that when you assign an object to another variable, both variables will refer to the same object in memory. Any changes made to the object through one variable will be reflected when accessing the object through the other variable.
