Can we overload new operator in Java?

The overloaded new operator function can accept arguments; therefore, a class can have multiple overloaded new operator functions. This gives the programmer more flexibility in customizing memory allocation for objects.

Can I create new operator using operator overloading in C++?

Two operators = and & are already overloaded by default in C++. For example, to copy objects of the same class, we can directly use the = operator. We do not need to create an operator function. Operator overloading cannot change the precedence and associativity of operators.

How many overloaded delete operator can be defined in a class?

In one class delete operator can be overloaded only once. In one class new operator can be overloaded multiple times. When we create object of the class with “new” operator the class overloaded new function will get called with the object size as a parameter.

What operators can be overloaded in C++?

Can all C++ Operators be Overloaded?

:: -Scope resolution operator.
?: -ternary operator.
. -member selector.
Sizeof operator.
* -member pointer selector.

Why operator overloading is not possible in Java?

Java doesn’t supports operator overloading because it’s just a choice made by its creators who wanted to keep the language more simple. Operator overloading allows you to do something extra than what for it is expected for. Java only allows arithmetic operations on elementary numeric types.

How is new operator implemented C++?

When new is used to allocate memory for a C++ class object, the object’s constructor is called after the memory is allocated. Use the delete operator to deallocate the memory allocated by the new operator. Use the delete[] operator to delete an array allocated by the new operator.

Can we overload increment operator in C++?

The postfix increment operator ++ can be overloaded for a class type by declaring a nonmember function operator operator++() with two arguments, the first having class type and the second having type int . Alternatively, you can declare a member function operator operator++() with one argument having type int .

Can delete operator be called twice?

Possible Duplicate: I know calling delete on same object is disastrous. But that is true as long as the memory is not reallocated for some other object before the second call to delete.

Does C++ support operator overloading?

In C++, we can make operators to work for user defined classes. This means C++ has the ability to provide the operators with a special meaning for a data type, this ability is known as operator overloading.
