Number of repeated characters in string array

Question

Hi,
I m trying to get number of repeated characters in string array. I couldnt figure out where am i doing mistake.
thank you,
For example: count({"alpha, beta,"}, 'a')
a is repeated 3
l is repeated 1 etc.
public class Test
public static int count(String[] stringArray, char c)
public String [] str = new String [2];
int count = 0;
str[0]
str[1]
for(int i = 0; i<str.length(); i++)
if (str.charAt(i)
count++;
return count;

There is a difference between a String and a String [].
A String [] is an array of String class objects:/*  Traverse_Array_Of_Strings_1.java */
public class Traverse_Array_Of_Strings_1
  public static void main(String [] argv)
    /* here is an array of Strings */
    String [] s = { "hello", "how", "are", "you" };
    int i, j;
    System.out.println("s.length = "+ s.length );
    for (i= 0; i < s.length; i++)
      System.out.println("s= <"+ s[i] +">");
      for (j= 0; j < s.length(); j++)
System.out.print(s[i].charAt(j) +", ");
System.out.println("\n-----");
}output:java> javac Traverse_Array_Of_Strings_1.java
java> java Traverse_Array_Of_Strings_1
s.length = 4
s= <hello>
h, e, l, l, o,
s= <how>
h, o, w,
s= <are>
a, r, e,
s= <you>
y, o, u,
