Java String Convert toLowerCase() Method

Date: 2023-06-22

Java's toLowerCase() method converts a string's characters to lowercase, returning a new string while leaving the original unchanged. It uses Unicode standards, handling most characters appropriately, but some characters without lowercase equivalents remain unaffected. The method is crucial for case-insensitive comparisons and operations, though locale-specific versions are available for accurate language-dependent conversions. Remember that Java strings are immutable, so toLowerCase() creates a new string object. Efficient usage involves minimizing unnecessary conversions and considering performance implications.
