What is the difference between Hash table and Array list?

"Difference between HashTable and Array List"

HashTable 

• • Hash Table is a collection of an object in Key and Value pair. And each object in the Hash Table is stored in a Key and Value format.
  • In Hashtable, searching operation is much faster than the array list.
  • For accessing of value in a hash table, you just need to pass key name.
  • It can store different types of data like int, char, String, Boolean etc.
  • In a hash table, the size of an element is not defined.
  • It stores a unique key object, in case of hash table key can’t be duplicate.
  • It is easily synchronized. And Hashtable is similar to HashMap which can store the value in key-value format.
  
  
  
  
  
  
  
  
  Array List
• Array List is the homogeneous collection of an element. And it can store each element in a particular index.
• In Array list, searching of the element is so difficult in comparison to the hash table.
• For accessing of value in an array list, you need to pass index number.
• It can store only similar types of element.
• It is created with initial (fixed length) size.
• It can store duplicate and dissimilar types of element.
• It is not easily synchronized.
