Java is a simple language to practice and develop more code in less time. All this is due to predefined API methods designers add in each version. Good examples are classes like **String**, **Character**, **GregorianCalendar** and **LinkedList** etc. They are designed as classes and methods are given to manipulate them. For example, **addFirst()** and **addLast()** methods add new links at the head and tail part of linked list without bothering link and address manipulations. The present context is **Character** class. Many methods are given to manipulate a character value. One such method is **toString()** method, overloaded two times.
