Leetcode || To Lower Case ( in 3 Ways ) || Easy || Java || Gopal

In this YouTube video, I provide three different solutions to the popular LeetCode question "To Lower Case" in Java. I explain each approach in detail, highlighting their advantages and disadvantages.

1. Approach 1: Using toLowerCase()
In the first approach, I demonstrate how to solve the problem using the built-in `toLowerCase()` method in Java.

2. Approach 2: String Concatenation
In the second approach, I showcase how to convert the string to lowercase by utilizing the `String` class and the `+` operator for concatenation. However, I discuss why this method can be inefficient for large strings due to its immutable nature and the creation of multiple intermediate string objects.

3. Approach 3: StringBuilder
Finally, in the third approach, I explain how to use the `StringBuilder` class for efficient string manipulation. I demonstrate how to iterate through each character of the string, check for uppercase letters, and convert them to lowercase using `StringBuilder`. I highlight the advantages of using `StringBuilder` over string concatenation.

By presenting these three different approaches, I aim to provide a comprehensive understanding of how to solve the "To Lower Case" LeetCode question efficiently in Java.
Join me in this video as we explore these solutions and gain valuable insights into Java programming techniques.
