What is Operator overloading? Is operator overloading a specific feature to C++ and not available in Java

With these it helps Operator overloading is a feature where the language allows you to define operators for your own types, so that you can write e.g. o1 + o2 where o1 and o2 are instances of your own type, instead of built-in types.
Operator-overloading is not specific to C++, but it's not available in java. Here's an example in Python:
code :
class Vector3D():
  def __init__(self, x, y, z):
    self.x = x
    self.y = y
    self.z = z
  def __repr__(self):
    return "Vector<%f,%f,%f>" % (self.x, self.y, self.z)
  def __add__(self, other):
    return Vector3D(self.x + other.x,
                    self.y + other.y,
                    self.z + other.z)

a = Vector3D( 1, 2, 3)
b = Vector3D(-1,-2,-3)
print a+b # Vector<0.000000,0.000000,0.000000>

I hope this helps you . Example one must be a non-member operator. Because operator+ has one or two arguments if a non-member but zero or one if a member. It has no special access to Jazz, it's the same as any other function in that respect. If you want to give it special access to Jazz you would declare it a friend (again just like any other function).
Example two must be a member, that's just a rule of C++, operator= must be a member function. You don't have to declare a copy constructor as well. It's just that's it's very common that if you need a copy constructor you will also need an assignment operator and vice versa.

I wish this helpful for you In C++, when you evaluate a function, you end up with a value (unless the function's return type is void). The type of a value is always an object type. So when you say f(), that expression is a value of type T. However, there are different categories of value:
code :
T    f();    =>   f() is a prvalue, passed along by copy
T &  f();    =>   f() is an lvalue, the same object that is bound to "return"
T && f();    =>   f() is an xvalue, the same object that is bound to "return"

wish help you to fix your issue Firstly, don't forget that this is deliberately bizarre code, used to find a corner case. If you ever find a type that behaves like this in a genuine program, find the author and have a quiet word with them.

should help you out
if a instance of Distance is to be returned in operator-() function shouldn't it be returned like new Distance(feet,inches)
