do-while loop in C

A do-while loop is a sort of loop construct in C that repeatedly runs a block of code as long as a stated condition is true. The do-while loop, as opposed to the while loop, ensures that the code block is performed at least once, even if the condition is initially false. The basic syntax of a do-while loop in C is as follows:

Array List

In Java, the ArrayList class implements the List interface as a resizable array. It offers dynamic arrays that can expand or contract in size as needed. ArrayLists are a component of the Java Collections Framework and provide a variety of methods for modifying the elements contained in them.

if Statement

If statement will execute a block of code if the given condition is true. The if statement checks a Boolean expression and executes the code based on if the expression is true

NullPointerException in Java

Vector In Java

A dynamic array implementation that is a part of the Java Collections Framework is the Vector class in Java. It offers a resizable array that can expand or contract as necessary. Similar to ArrayLists, vectors are thread-safe for use in multi-threaded situations since they are synchronised.

LinkedHashMap in Java

Java includes a number of data structures for storing and manipulating collections of objects. The 'LinkedHashMap' class, which is an extension of the 'HashMap' class, is one of the important classes in the Java Collections Framework. LinkedHashMap, unlike HashMap, preserves the order of its items depending on the insertion order, making it helpful in cases where the order of components must be maintained based on their arrival time.
