The entrySet() method of ConcurrentHashMap class returns a Set view of the mappings contained in this map. The changes made to the map are reflected in the set, and vice-versa.

Syntax

Parameter

No parameter is passed.

Returns

the set view

Throws

No exception is passed.

Example 1

  import java.util.*;  import java.util.concurrent.ConcurrentHashMap;    public class ConcurrentHashMapentrySetExample1 {     public static void main(String args[]) {               ConcurrentHashMap  mymap = new ConcurrentHashMap();           mymap.put(“AA”, “Java”);        mymap.put(“BB”, “angular”);        mymap.put(“CC”, “JavaScript”);          Set myset = mymap.entrySet();        System.out.println(“myset values: ” + myset);     }      }  

Test it Now

Output:

myset values: [AA=Java, BB=angular, CC=JavaScript]

Example 2

  import java.util.*;  import java.util.concurrent.ConcurrentHashMap;    public class ConcurrentHashMapentrySetExample2 {     public static void main(String args[]) {               ConcurrentHashMap  mymap2 = new ConcurrentHashMap();           mymap2.put(1, 101);        mymap2.put(2, 102);        mymap2.put(3, 103);        mymap2.put(4, 104);        mymap2.put(5, 105);        mymap2.put(6, 106);          Set myset = mymap2.entrySet();              System.out.println(”  “+myset.toString());              }     }      

Test it Now

Output:

[1=101, 2=102, 3=103, 4=104, 5=105, 6=106]
