    Default Can we have something like myintarray[a] = 0 where "a" is a string value??

    Say if we have String s = "abcdefg"

    is it possible to do something like this

    myArray[a] = 0
    myArray[b] = 1
    myArray[c] = 2
    myArray[d] = 3
    myArray[e] = 4
    .
    .
    .

    where a,b,c,d,e ... are string values

    Many Thanks

    No it isn't possible, as the values are integer pointers to data.
    You could however do myIntArray[Integer.valueOf("23")] = 2; if you so desired.

    What does the String s have to do with the rest of your question? Do you want the array indices to equal the index of the character? If so, String has methods to do just that. The API is your friend.

    Sounds like you want to use a Map. The String would be the key to get a value from the Map.
    value = theMap.get("a String");
