Comparing Strings in Java with Special Considerations for Null and Empty Values

In Java development, handling String comparisons where either or both strings might be null or empty (i.e., "") is a common challenge. Specifically, situations arise where null values should logically equate to empty strings. This requirement is particularly useful in applications dealing with user inputs or data interchange where the absence of a string (null) is effectively the same as an empty string. Today, we’ll explore different methods to implement this comparison logic in Java.
