Example 1

  import java.util.*;  import java.util.concurrent.ConcurrentHashMap;    public class ConcurrentHashMapequalsExample1  {     public static void main(String args[]) {               ConcurrentHashMap  mymap = new ConcurrentHashMap();          ConcurrentHashMap  mymap2 =  mymap;                      mymap.put(“AA”, “Java”);        mymap.put(“BB”, “angular”);        mymap.put(“CC”, “JavaScript”);                        System.out.println(“comparing mymap and mymap2 :” +mymap.equals(mymap2));     }      }  

Test it Now

Output:

comparing mymap and mymap2 :true

Example 2

  import java.util.*;  import java.util.concurrent.ConcurrentHashMap;    public class ConcurrentHashMapequalsExample2  {     public static void main(String args[]) {               ConcurrentHashMap  mymap = new ConcurrentHashMap();          ConcurrentHashMap  mymap2 = new ConcurrentHashMap();                mymap2.put(1, 101);        mymap2.put(2, 102);        mymap2.put(3, 103);               mymap.put(“AA”, “Java”);        mymap.put(“BB”, “angular”);        mymap.put(“CC”, “JavaScript”);                        System.out.println(“comparing mymap and mymap2 :” +mymap.equals(mymap2));     }      }
