Tag: Java reference types

Java has two categories of data: Primitive Data Type: such as boolean, char, int, short, byte, long, float, and double . Non-Primitive Data Type or Object Data type: such as String, Array, etc.

In Java there are four types of references differentiated on the way by which they are garbage collected.

Primitive Data Type: In Java, the primitive data types are the predefined data types of Java . They specify the size and type of any standard values. Java has 8 primitive data types namely byte, short, int, long, float, double, char and boolean.

Reference datatypes in java are those which contains reference/address of dynamically created objects . These are not predefined like primitive data types. … class types − This reference type points to an object of a class. array types − This reference type points to an array.

The short answer is primitives are data types, while references are pointers, which do not hold their values but point to their values and are used on/with objects .9 Oca 2012
