Let’s see few examples of HashSet in Java. 1. Adding duplicate elements HashSet overrides duplicate values. importjava.util.HashSet;publicclassHashSetExample{publicstaticvoidmain(Stringargs[]){// HashSet declarationHashSet<String>hset=newHashSet<String>();// Adding elements to the HashSethset...
hashSet.forEach(System.out::println);// Output// four// one// two// threeCode language:Java(java) We have added 5 elements but HashSet has only 4. Because, It ignored the second “one”. We added elements in the incremental order of “one”, “two” etc. But, the output has di...
HashMap is a hash table based implementation of the Map. In Java, Map is a key value based collection. Therefore Hashmap also stores the data in the form of key/value pairs. HashMap is an unordered, and unsorted collection of key value pairs where a key is always Unique. HashSets ...
crunchifyPrint("crunchifyHashMapNew Details: "+ crunchifyHashMapNew); // Returns a Set view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the se...
