Autoboxing is the automatic conversion of primitive data types to their corresponding object wrapper classes.
Autoboxing is useful when working with collections that require objects instead of primitives.
Example: int i = 5; Integer j = i; //autoboxing
Unboxing is the opposite of autoboxing, where an object of a wrapper class is converted back to its corresponding primitive type.
Example: Integer j = 5; int i = j; //unboxi
Typecasting up and down refers to converting a variable of one data type to another data type of higher or lower precision.
Typecasting up involves converting a variable of lower precision to a variable of higher precision, such as converting an int to a double.
Typecasting down involves converting a variable of higher precision to a variable of lower precision, such as converting a double to an int.
Typecasting can resul...
