This is my first time working with java so please bear with me. So imagine an 26x26 checkerboard (or chessboard). I need to know how to properly convert a checkerboard's coordinates to the corresponding row and column number. For example, z19 corresponds to a piece on the 26th column and 19th row. I've already gotten most of the code down using a hash table but the trouble i'm having is when I input a double digit number, the output i get are the two digits, BUT separated. For example:

```
Input: z19
Output:
26
1
9

```

How can i fix this issue? 
Here is my method:

```
public static void hash(String coordinates){

        HashMap hash = new HashMap();
        hash.put("a", 1);
        hash.put("b", 2);
        hash.put("c", 3);
        hash.put("d", 4);
        hash.put("e", 5);
        hash.put("f", 6);
        hash.put("g", 7);
        hash.put("h", 8);
        hash.put("i", 9);
        hash.put("j", 10);
        hash.put("k", 11);
        hash.put("l", 12);
        hash.put("m", 13);
        hash.put("n", 14);
        hash.put("o", 15);
        hash.put("p", 16);
        hash.put("q", 17);
        hash.put("r", 18);
        hash.put("s", 19);
        hash.put("t", 20);
        hash.put("u", 21);
        hash.put("v", 22);
        hash.put("w", 23);
        hash.put("x", 24);
        hash.put("y", 25);
        hash.put("z", 26);
        hash.put("1", 1);
        hash.put("2", 2);
        hash.put("3", 3);
        hash.put("4", 4);
        hash.put("5", 5);
        hash.put("6", 6);
        hash.put("7", 7);
        hash.put("8", 8);
        hash.put("9", 9);
        hash.put("10", 10);
        hash.put("11", 11);
        hash.put("l2", 12);
        hash.put("13", 13);
        hash.put("14", 14);
        hash.put("15", 15);
        hash.put("16", 16);
        hash.put("17", 17);
        hash.put("18", 18);
        hash.put("19", 19);
        hash.put("20", 20);
        hash.put("21", 21);
        hash.put("22", 22);
        hash.put("23", 23);
        hash.put("24", 24);
        hash.put("25", 25);
        hash.put("26", 26);
    String word = new String(coordinates);
    char array[] = word.toCharArray();
    for(char c: array) {
        System.out.println(hash.get(String.valueOf(c)));
    }
    }

```

One thing I forgot to mention: I want to also be able to input different coordinate points simultaneously. For example, if I type this in:

```
Input: a4c23d17

```

I want it to output this:

```
1
4
3
23
4
17

```
