classes and objects in java

class <className> 
 { 
 public: 
     (public member data and functions go here) 
 private:
     (private member data and functions go here) 

 };

// Default behavior of toString() is to print class name, then
// @, then unsigned hexadecimal representation of the hash code
// of the object

public String toString()
{
    return getClass().getName() + "@" + Integer.toHexString(hashCode());
}
