Understanding ArrayList and HashMap in Java

Java, a popular programming language, offers a rich set of data structures through its Collection Framework. Among these, ArrayList and HashMap are fundamental classes that serve distinct purposes and possess unique functionalities. Let’s explore these two classes, highlighting their similarities, differences, and use cases.

ArrayList: Dynamic Arrays in Java

ArrayList, residing in the java.util package provides dynamic arrays in Java programming. Despite being potentially slower than standard arrays, it proves invaluable in scenarios demanding frequent array manipulations. It implements the List interface, enabling operations such as addition, retrieval, and removal of elements.

Understanding Code Profiling in Software Development

Code profiling stands as a cornerstone in modern software development, providing developers with invaluable insights into their code’s behaviour and performance

This process involves collecting and analysing data during program execution, allowing for the identification of bottlenecks and areas for optimisation.

What is Profiling?

At its core, profiling entails the meticulous analysis and recording of information pertaining to a specific phenomenon. In the realm of app and website development, this translates to gathering data on a program’s execution, resource usage, and performance characteristics.

Diverse Profiling Collection Techniques

Statistical Profiling: This method intermittently interrupts program execution to record the call stack, offering a rough estimation of where the program expends its time.
