Hashtable vs HashMap inwards Java
Hashtable as well as HashMap are 2 hash based collection inwards Java as well as used to shop objects equally telephone commutation value pair. Despite beingness hash based as well as similar inwards functionality at that spot are a pregnant divergence betwixt Hashtable as well as HashMap as well as without agreement those divergence if yous usage Hashtable inwards house of HashMap than yous may meet serial of subtle programs which is difficult to notice as well as debug.Unlike Difference betwixt ArrayList as well as HashMap, Difference betwixt Hashtable as well as HashMap are to a greater extent than subtle because both are similar form of collection. Before seeing divergence betwixt HashMap as well as Hashtable let's consider to a greater extent than or less mutual things betwixt HashMap as well as Hashtable inwards Java.
Similarities betwixt Hashtable as well as HashMap inwards Java
There are lot of similar things betwixt Hashtable as well as HashMap inwards Java which is skilful to know as well as these likewise helps to notice just what is unlike betwixt HashMap as well as Hashtable inwards Java:
1) Both Hashtable and HashMap implements java.util.Map interface.
2) Hashtable and HashMap both are a hash based collection as well as industrial plant on the regulation of hashing.
3) Hashtable and HashMap both supply constant fourth dimension surgery for position as well as larn method if objects are distributed uniformly across bucket.
4) From JDK four both Hashtable and HashMap are component subdivision of Java collection framework.
Despite beingness hence similar at that spot are to a greater extent than or less differences betwixt Hashtable as well as HashMap inwards Java which separates them completely, let's bring a hold off :
1) First as well as close significantly unlike betwixt Hashtable and HashMap are that HashMap is non thread-safe spell Hashtable is a thread-safe collection.
2) The minute of import divergence betwixt Hashtable as well as HashMap is surgery since HashMap is non synchronized it perform meliorate than Hashtable.
3) The tertiary divergence on Hashtable vs HashMap is that Hashtable is obsolete shape as well as yous should live on using ConcurrentHashMap inwards house of Hashtable inwards Java.
These were to a greater extent than or less of import divergence on Hashtable as well as HashMap inwards Java. If yous know whatsoever other divergence which is non included hither hence feels costless to add together them inwards the comment section. Remember this is an of import query on Java interview as well as skilful to cook it well.
