public static void main(String[] args) {
//creating hashtables
Hashtable<Integer, String> Htable1 = new Hashtable<Integer, String>();
Hashtable<Integer, String> Htable2 = new Hashtable<Integer, String>();
Hashtable<Integer, String> Htable3 = new Hashtable<Integer, String>();
//populating Htable1
Htable1.put(101, "John");
Htable1.put(102, "Marry");
Htable1.put(103, "Kim");
//populating Htable2
Htable2.put(101, "John");
Htable2.put(102, "Marry");
Htable2.put(103, "Kim");
//populating Htable3
Htable3.put(1, "JAN");
Htable3.put(2, "FEB");
Htable3.put(3, "MAR");
//checking Htable1 and Htable2 for equality
System.out.print("Are Htable1 and Htable2 equal? : ");
System.out.println(Htable1.equals(Htable2));
//checking Htable1 and Htable3 for equality
System.out.print("Are Htable1 and Htable3 equal? : ");
System.out.println(Htable1.equals(Htable3));
}
}
The output of the above code will be:
Are Htable1 and Htable2 equal? : true Are Htable1 and Htable3 equal? : false
