  • Class and array are different structures. They both have different interface. Java has pool for String literals. Single char can't represent all symbols like ones created by surrogate pairs (), so String also provides support for codepoints, not only characters. – Pshemo Aug 21 '16 at 17:25

String is the class that contains into itself char array, as well as different ready methods for you. When you use simply char array you must implement your own methods, while String has already built-in popular and optimized methods.
