Autoboxing is the automatic conversion that the Java compiler makes between the primitive types and their corresponding object wrapper classes. For example, converting an int to an Integer, a double to a Double, and so on. If the conversion goes the other way, this is called unboxing.

Boxing and Unboxing

Comment

//"Boxing" is the operation of converting a covert value type stored in the stack to an object (a reference value) stored in the heap.
//This means creating a new heap object and copying the value of the value type into it.
//ex 

int i =10;
object o = i;

// Make a new heap object or reference and copy i's value into it.

//"UnBoxing"  It is the inverse of boxing in that the object is unboxed and a new variable with the object's value is created in the stack.

//ex

object boxed = 123;
int unboxed = (int) boxed ;

// Take note that it says "require casting," as there are risks in doing so.

//Boxing is implicated Unboxing is explicit casting.
