According to wikipedia, a (primitive) wrapper class in Java is one of those eight classes that wrap a (=one) primitive value. String wraps a char[] so according to this it is not a (primitive) wrapper class.
Furthermore, String is not designed to wrap or decorate a character array. String has been designed to model a string, a character sequence and the current implementation uses an internal char[]. But Sun could also have chosen to use a byte[] a long with a character encoding hint, a collection or something native. That doesn't matter.
That's different for the primitive wrappers: they have been designed only to wrap a primitive, to adapt a java primitive to java.lang.Object.

No. String is not a wrapper class, simply because there is no parallel primitive type that it wraps.
From wiki:
A primitive wrapper class in the Java programming language is one of eight classes provided in the java.lang package to provide object methods for the eight primitive types

Wrapper Classes in Java
April 26, 2024 - To get a primitive data type value corresponding to a string value, you can use the static utility method parseDataType. Each wrapper class (except Character) defines a method to parse a String to the corresponding primitive value.

August 19, 2022 - The wrapper classes in java servers two primary purposes. To provide a mechanism to ‘wrap’ primitive values in an object so that primitives can do activities reserved for the objects like being added to ArrayList, Hashset, HashMap etc. collection. To provide an assortment of utility functions for primitives like converting primitive types to and from string objects, converting to various bases like binary, octal or hexadecimal, or comparing various objects.

Initially, the CustomIntWrapper object is created with a value of 10. After each operation (increment, add, subtract), the value of the CustomIntWrapper object is updated accordingly, and the object’s string representation is printed. Object-oriented compatibility: Wrapper classes allow primitive data types to be treated as objects, facilitating their use in object-oriented paradigms like inheritance and polymorphism.

October 16, 2024 - For instance, Java’s ArrayList can store objects but not primitive types. By using wrapper classes, we can store primitive values in collections like ArrayList or HashMap. ArrayList<Integer> numbers = new ArrayList<>(); numbers.add(5); // Here, the int 5 is "wrapped" into an Integer object. 2. Utility Methods: Wrapper classes provide several useful methods. For example, the Integer class has methods like parseInt() to convert a String into an int.

January 21, 2025 - It provides methods for converting between booleans and substring in Java and methods for type casting between boolean primitives and their corresponding wrapper classes. To Reverse a String in Java, you have to use the Wrapper class that can convert a string to its corresponding primitive data type and can wrap that primitive data type.
