Type casting is when you assign a value of one primitive data type to another type.
In Java, there are two types of casting:
- Widening Casting (automatically) - converting a smaller type to a larger type sizebyte -> short -> char -> int -> long -> float -> double
- Narrowing Casting (manually) - converting a larger type to a smaller size typedouble -> 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.
here (int) is the used in parentheses in front of the value to convert double data type to int data type.
