Obj.put("b", New Integer(2)); 7. Obj.put("c", New Integer(8)); 8. System.out.print(obj.tostring()); 9. } 10. }

Answer»

obj.toString returns String EQUIVALENT of the HASHTABLE, which can also be obtained by SIMPLY writing System.out.PRINT(obj); as print system automatically coverts the obj to string equivalent.

Output:

$ JAVAC hashtable.java
$ java hashtable
{A=3, C=8, B=2}

obj.toString returns String equivalent of the hashtable, which can also be obtained by simply writing System.out.print(obj); as print system automatically coverts the obj to string equivalent.

Output:

$ javac hashtable.java
$ java hashtable
{A=3, C=8, B=2}
