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.
