Notice that there are no *'s or &'s in the code to create pointers. The code intrinsically uses pointers. Also, the garbage collector (Section 4), takes care of the deallocation automatically at the end of the function. public void JavaShallow() { Foo a = new Foo(); // Create a ...

Debugging these errors is the best option in front of us. But debugging is not an easy task, because there is no one-size-fits-all technique when it comes to debugging. That is why we are going to use our Java Stack Trace for handling these errors and exceptions. Head into the blog ...
The apache commons codec Base64 methods were used to encode/decode string. The keys were hard coded to prevent anyone to get the keys and use to decrypt string. Below is the example class of EncryptDecrypt.java. Change SECRET_KEY_1 and SECRET_KEY_2 to your own secret keys....
Usestd::shared_ptrfor Multiple Pointers to Refer to the Same Object in C++ Since the manual management of dynamic memory happens to be quite hard for real-world projects and often is the main cause of the bugs, C++ provides the concept of smart pointers as a separate library. Smart pointer...
In Java, we use a reference type to gain access to an object, and when we don’t have a specific object to make our reference point to, then we set such references tonullto imply the absence of a value. The use ofnullis so common that we rarely put more thought into it. For exa...
In C++, pointers are not safe inherently. When we dereference a pointer, it is our responsibility to ensure that it points at a valid address. In this article, we will discuss three methods to check if a pointer is NULL in C++. Table of Contents [hide] Comparison with nullptr ...
