null


null is a Java reserved word representing no value. Assigning null to a non−primitive variable has the effect of releasing the object to which the variable previously referred. Null cannot be assigned to variables of primitive types (byte, short, int, long, char, float, double, boolean)

Syntax:
datatype variable = null;


Example:

Integer i;
i = null;
String s;
if (s != null)
{

}
