Mapping a String to an array of ints - Java

Question

How do I map a String to a statically defined array of ints? I tried

private static Map<String, int[]> map = new HashMap<String, int[]>();
static {
    map.put("foo", {5, 1, 3, 2});
    map.put("bar", {2, 7, 8});
}

which tells me that {5, 1, 3, 2} is illegal.

Answer 1

You need to call the array's constructor before you initialize the content.

map.put("foo", new int[]{5, 1, 3, 2});

Answer 2

Try

private static Map<String, int[]> map = new HashMap<String, int[]>();
static {
    map.put("foo", new int[]{5, 1, 3, 2});
    map.put("bar", new int[]{2, 7, 8});
}
