Hexa To Decimal Conversion In Java Explained Step-by-Step | Master In Looping in Java
In this tutorial, we will learn how to convert a Hexadecimal Number to Decimal in Java using a clear and step-by-step approach. This video is specially designed for ICSE Class 10, ISC Class 11 & 12 Computer Science students, as well as B.Tech, BCA, MCA, CS, IT, and IIT-level students who want to strengthen their understanding of number system conversions and improve their logical programming skills.
The Hexadecimal to Decimal Conversion program is an important concept in computer science because the hexadecimal number system (base 16) is widely used in memory addressing, machine language, digital electronics, color coding, and low-level programming. Understanding hexadecimal-to-decimal conversion helps students build strong fundamentals in computer organization, digital logic, data representation, and programming concepts.
In this video, you will learn how to extract hexadecimal digits, convert hexadecimal characters such as A, B, C, D, E, and F into their decimal equivalents, apply the power of 16 concept, and calculate the decimal value step-by-step. The tutorial includes clear explanation of logic, complete Java program writing, manual dry run, and output verification, making it ideal for beginners as well as intermediate learners.
This program is frequently asked in ICSE and ISC board exams, university practical exams, coding assignments, and technical interviews, making it an essential topic for Java learners.
