Any type of storage that stores an address or we can say reference of object in memory, called Reference data type. Java like other language have also some reference data types discussed in the article.
Broadly a reference in Java is a data element whose value is an address of a memory location. Arrays (a group of similar data items), classes (a blue print of some entity e.g. a student) and interfaces are reference type. The value of reference type variable, in contrast to that of primitive type, is a reference to (an address of) the value or set of values represented by variables.
A reference is called a pointer, or memory address in other language. The java programming language does not support the explicit use of addresses like other languages do. You use variable’s name instead.
An importance reference type that you use in Java is String type. The String type lets you create variables that can hold textual data e.g. “Mohan”, TZ194”, “194ZB”, “234” etc. Anything that you enclose in double quotes is treated as text in Java.
