How would I solve this if the second input of count (String str, char character) is a char and not a string like in the following program? { public static void main (String [] args) { System.out.println (count ("heloo anna", "a")); }

public static int count(String str, String character) { if(str.length()==0) { return 0; }

if ((str.substring(0,1).equals(character))) { return 1 + count(str.substring(1), character); }

return countChar(str.substring(1), character); } }
