The Wrapper classes in Java have a static implementation of the toString() method as well. RowSetMetaDataImpl. An object is needed to support synchronization in multithreading. Overloading always occurs in the same class (unlike method overriding). Wrapper classes wrap primitive data type value into a class object. The main method accepts as arguments the name of the wrapped class followed by its arguments. If two or more method in a class has the same name but different parameters, it is known as method overloading. and for converting characters from uppercase to lowercase and vice versa. Uses of wrapper classes in Java are as follow-, The automatic conversion of primitive data type into its corresponding wrapper class is known as autoboxing, for example, byte to Byte, char to Character, int to Integer, long to Long, float to Float, boolean to Boolean, double to Double, and short to Short.
