有没有比这更有效的方法来引用带有字符串的 int 数组

Question

I have hundreds of small arrays each holding two ints representing an x, y coordinate on the screen. The method passes in a string with the same name as the array holding its values. Rather than hard coding each case like this...

public class Main {

    int[] a = {1000, 500},
          b = {900, 400},
          c = {800, 300};

    public method(String tile) {
        int x = 0, y = 0;

        switch(tile) {
        case "a": x = a[0]; y = a[1];
        case "b": x = b[0]; y = b[1]; 
        case "c": x = c[0]; y = c[1];
        }
    }       
}

How can I do this more efficiently?

Answer 1

public static void main(String[] args) {

    int[] a = {1000, 500};
    int[] b = {900, 400};
    int[] c = {800, 300};

    Map<String, int[]> stringToTile = new HashMap<>();
    stringToTile.put("a", a);
    stringToTile.put("b", b);
    stringToTile.put("c", c);

    testMethod("a", stringToTile);
    testMethod("b", stringToTile);
    testMethod("c", stringToTile);
}

public static void testMethod(String tile, Map<String, int[]> stringToTile) {
    int[] resultArray = stringToTile.get(tile);
    int x = 0, y = 0;
    if (resultArray != null) {
        x = resultArray[0];
        y = resultArray[1];
    }
    System.out.println(String.format("x: %s; y: %s", x, y));
}

Instead of using array, you can use object as well. I wonder if this helps.
