Array of Characters, Need Help
Please i am new to java. Can someone kindly give me a java code that will do this Assignment ?
Write a function that accepts a character array as input, counts the number of occurrences of each character in the array, and outputs the results in a format like the following (characters that do not occur in the input array are not displayed in output)
a - **
c - ****
e - *
For example, if input were {慶? 慹? 慹? 慹? 慳? 憅拀, the output would be:
a - *
c - *
e- ***
q - *
Thank you all.

there are lots of way to do this ; i give you one:
- create a two dimensions table of int new int [26][2]; (i take 26 for the 26 letters of the alphabet)
- each letter of the alphabet will be filled in the first dimension ; the second dimension will be to count occurence of each letter
- you browse the input, and increment total for each character
- once this is over, you browse your int[][] table using the second dimension to determine how much * you must write for each character
> Thank you all.
you re welcome
EDIT: you can also use a HashMap<Character, Integer> if you don't like the first solution
