How to Extract and Sum Digits in a String? | JAVA INTERVIEW QUESTIONS

In this comprehensive tutorial, we delve into one of the most commonly asked Java technical interview questions: calculating the sum of digits within a string. This video will guide you step by step on how to write a program that extracts every digit from a provided string, which may contain letters, special characters, and digits, and then returns the sum of these digits.

Using a practical example, we explain each line of code, the methods used, and the logic behind them. We cover essential Java concepts such as using a for loop to iterate through characters, verifying digit characters, and converting them to integers.

Whether you're a Java beginner seeking to learn new skills or a professional brushing up before a technical interview, this video will provide you with valuable knowledge and insights.
