When writing programs in java, we often deal with scenarios where we get null reference for objects. Such scenarios are pain for developers, as de-referencing such variables cause, you guessed it, null pointer exceptions. The standard practice, for developers, before Java 8, was to null check every time you faced such ambiguous instances of objects.
Number of digits in 12345 is 5. Example using while Loop Output Execution of program: count initalize to 0, num to 12345 while loop body will execute if num != 0 num = num /10; Here, 12345 /10 result in 1234.5 since num is integer decimal number is ignored. the value of num becomes 1234
This is an intro to Angular and VS Code. So in the last article we learned how to use Angular CLI to auto generate starter code for our angular app and how to run it. In this article we will focus on how Angular structures its files, what they do and how we can get
Angular Web App Development. Now that we have our environment all set up, we can start installing Angular Essentials which include Angular CLI (Command Line Interface).

In this tutorial, we will learn about the inheritance in C++, its important and use with detailed example. Definition:Acquiring the properties of parent class to sub class objects is called Inheritance” Concept of Inheritance Base Classes and Derived Classes In above diagram, Car is Base class where as pickup truck and truck class is dervied
In this article, we will learn about inline functions, its working and how it is different than normal function in C++. Inline function is function from which compiler copies code into calling function directly rather than branching to the called function. Since there is no branching and code is directly inserted it eliminates the performance
User defined methods in java: Functions are called methods in java. Like in C, java programming has similar user defined methods. There are basically four types of user defined methods.
