I am trying to find the specific character within a String Array. What must I use?

Question

Below is the code.\ I imagine you use a for loop and then another but I cannot seem to make it work. I attempted research however most topics were too complex since I am a novice. I'm trying to find a way to get the fifth character out of each string within the variable. I'll use the information given to me so i can then solve the rest of my program. I have more to do

public static void main (String[]args)
    {
        String[] decoder = {"Nexa2f5", "Z52Bizlm" , "Diskapr" , "emkem9sD", "LaWYrUs", "dAStn78L", "mPTuriye", "aaeeiuUu", "IL8Ctmpn"};
        int character = 4;
        for(int i=0; i<=decoder.length-1; i++)
        {

        }
    }

I am trying to get the third and fourth characters of the odd numbered Strings. I am trying to put the letters into an array and decode the message. I am also trying to print the 5th character of all other words. I'm having issues commenting right and I've tried to reply a couple times but no dice.

Do you need to find the string "4" or the asci character represented by 4? If you need to find the location of the string "4", something like http://stackoverflow.com/questions/2275004/in-java-how-to-check-if-a-string-contains-a-substring-ignoring-the-case should work. — aplassard, Apr 21 '14 at 00:56

Here is what I would do:

    String[] decoder = {"Nexa2f5", "Z52Bizlm" , "Diskapr" , "emkem9sD", "LaWYrUs", "dAStn78L", "mPTuriye", "aaeeiuUu", "IL8Ctmpn"};
    for (String s: decoder){
        String myChar = s.substring(4, 5);
        // now continue to process myChar
    }

class test {
    public static void main (String[]args)
    {
        String[] decoder = {"Nexa2f5", "Z52Bizlm" , "Diskapr" , "emkem9sD", "LaWYrUs", "dAStn78L", "mPTuriye", "aaeeiuUu", "IL8Ctmpn"};
        int character = 4;
        for(int i=0; i<=decoder.length-1; i++)
        {
        String temp = decoder[i];
        System.out.println(temp.substring(4,5));
        }
    }
}

 for(String s : decoder) {
      for(char c : s.toCharArray()) {
           //loops through ever char of every string
      }
 }

 char letter;
 for(String s : decoder) {
      if(s.length > 4) {
           letter = s.chatAt(5);
      }
 }

Choose your weapon. I'm not completely sure how you want to do this, but this is the format you'd want for looping through variables in an array.
