      // put values in two tables
      htable1.put(1, "A");
      htable1.put(2, "B");
      htable1.put(3, "C");
      htable1.put(4, "D");
      htable2.put(1, "A");
      htable2.put(2, "B");
      htable2.put(3, "C");
      htable2.put(4, "from");
      // check equality
      boolean isequal=htable1.equals(htable2) ;
      // display result
      System.out.println("Are two tables equal:"+isequal); 

The code above generates the following result.
