// You can typecast to convert a variable of one data type to another.
// Wide Casting converts small data types to larger ones.
// Narrow Casting converts large data types to smaller ones.
// Java can automatically Wide Cast.
// Java will throw an error when trying to automatically Narrow Cast.
// This is because data is often lost when Narrow Casting.
// Narrow Casting must be done manually.
//Wide Cast:
int SomeNumber = 5;
double WideCastedNumber = (double)SomeNumber;
//Narrow Cast:
double SomeNumber = 5.39;
int NarrowCastedNumber = (int)SomeNumber;
//Note: The data that holds the decimal places will be lost!промяна на вида в c

типизация на 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.

JAVA: Example of cast:
int SomeNumber = 5; //int
double WideCastedNumber = (double)SomeNumber; //from int to double
double myDouble = 9.78;
int myInt = (int) myDouble; // from double to intкакво е типизация
