Day 2 - Code Java Smart | Counting Digits
Welcome to Code Java Smart, where we explore efficient and optimized approaches to Java programming. In today's video, we uncover two smart ways to count the digits of a number in Java—using Math.log10 and String.length function. Why These Approaches? Instead of using a traditional loop to count digits one by one, these methods offer a more efficient solution: Math.log10(n) + 1 provides a quick mathematical way to determine digit count. String.valueOf(n).length() leverages Java’s built-in string processing for a simple and readable approach.
In This Video, You’ll Learn:
✅ How Math.log10 helps compute the number of digits efficiently
✅ How String.length() provides an alternative intuitive method
✅ The advantages and edge cases of both approaches
✅ A step-by-step Java implementation
