hello
I have this code below which maps out my string keys with string values; once it has maped them out it gets the string keys in the order that they are maped out at.
my problem is that i want to map some integers out with them ( int keys[]={0,1,2,3,4,5,6,7,8,9} )
How would i do this?
please help me

ints are primitives, they can't be stored in hashmaps. Use the Integer wrapper class, and store those wrappers in the hashmap:

You can create another hashtable that will map the values in the int array to either key or value
of your original key or value array.For this you have to convert int primitive type to Integer object because in the hashtable you can use only objects as key or value.
Then use this hashtable as key or value to construct the final hashtable.
