Moilanen's (1995) study of adolescent depression also attempts to validate Beck's theory in a new way, as Beck worked mostly with adults. Indeed, she found that the student's depression was often associated with dysfunctional beliefs and negative future attitudes.
A hash code is a numeric value that is used to insert and identify an object in a hash-based collection such as the Dictionary<TKey, TValue> class, the Hashtable class, or a type derived from the DictionaryBase class.
hashCode() method is nothing but it gives unique identity(Hash Code number) to the object. It defines the uniqueness of the object. Default implementation of hashCode() is given in such a way that it returns the Hash Code number for the object based on the address of the object. JVM automatically generates this unique number based on the address of the object.
