@ -13,6 +13,8 @@ Java, type casting is classified into two types.
***1. Implicit Typecasting***
Here, Automatic Type casting take place when the two types are compatible
the target type is larger than the source type.
Datatype precedence for implicit type casting (widening) is as follows :
`byte -> short -> int -> long -> float -> double`
eg.
``` java
int i = 100;
@ -20,7 +22,8 @@ eg.
float f = l; //no explicit type casting required

***2. Explicit Typecasting***
When we assign a larger type value to a variable of smaller type, then we need to perform explicit type casting.
When we assign a larger type value to a variable of smaller type, then we need to perform explicit type casting. Datatype precedence for Explict type casting (narrowing) is as follows :
`byte <- short <- int <- long <- float <-double`
