typecasting java
Assigning a value of one type to a variable of another type is
known as Type Casting.
Auto-boxing; is a process when you take a primitive value and
assign into wrapper class object.
Un-boxing; is a process when you take Wrapper class object
and convert to primitive.casting in java
Primitive Type casting and Reference Type casting
PRIMITIVE CASTING:
implicit casting (casting smaller type to larger
int a = 100; double c = a;)
explicit casting (casting larger to smaller
byte b = (byte) a;
REFERENCE CASTING:
upcasting - implicitly done (casting smaller type to larger)
Collection<Integer> collection = new ArrayList<>();
downcasting (cast larger type to smaller one )
List <Integer> list = ( ArrayList ) collection;
FRAMEWORK EXAMPLE:
Up Casting, Down Casting in Multi Browser testing.
WebDriver, Chrome Driver, Firefox Driver object
I casted to WebDriver to making reference type.
Whenever you taking Screenshots,
whenever executing Java script command.java casting method
Animal animal = new Dog ();
animal.fetch(); // Compiler error
(Dog) animal.fetch();typecasting java
