Type Casting in JAVA

Type casting is when you assign a value of one primitive data type to another type.

byte -> short -> char -> int -> long -> float -> double
Narrowing Casting (manually) - converting a larger type to a smaller size type
double -> float -> long -> int -> char -> short -> byte

Widening casting is done automatically when passing a smaller size type to a larger size type:

Narrowing casting must be done manually by placing the type in parentheses in front of the value:
