Counting Letter Frequency

[supervi]

Hello,
I need to write a java program that will take a string input from a user and output the frequency of each letter in the word. I could use long case statements but I think there might be a more efficient way of doing this.

When the user inputs a string, does each letter correspond to an integer value?

Thanks in advance for any guidance.

Puzzled.

Convert the String to a char[] array, then loop the array, incrementing a count for each occurrence of your desired char.

I'm not sure if you mean the number of ocurrences of each letter or the audio frequency when you pronounce it.

Anyway, to get that value:

String myString = "someChars";
for (int i=0; i<myString.size(); i++)
  System.out.println((int) myString.charAt(i));

Cheers,
