Introduction

Java is one of the most popular programming languages and remains in high demand. In 2025, it continues to rank among the top five languages, powering nearly 90–95 % of Fortune 500 companies and supporting domains such as cloud-native applications, big data, Android development, finance, and the Internet of Things (IoT).

Due to its portability, the need for Java skills is increasing by leaps and bounds. Java is intended for application developers to write code and run it on any computer. The growing popularity can also be attributed to MNCs and other organizations using Java to create backend systems and web applications.
