Hi All,
I made this simple program for inserting elements in2 a Map and then displaying the elements of the Map :



THe program does not compile...it gives an error :



Why ? The put() method takes two objects as parameters.
I have converted the primitive values to their respective Object types...still the error ??

Please help...
