which is better arraylist or dictionary?..

Answer / lavanya

arraylist accepts any type of object. when we create an
arraylist it allows duplicate values.
in dictionary it maintains key and value which is specific
type (i.e, either its int or string or any datatype)
it will not allow duplicates.
so dictionary is better in some requirements.
