我已经将set1声明为静态字符串[]，我希望将set2声明为set1+少数其他参数。是否可以声明set2与set1静态相似(即private static string[])但使用上述定义，如果不是，如何这样做？

private static final String[] SET1 = {"1","2","3" };

SET2 = SET1 + {"4","5","6" };

Look at commons utile arrayutils.Add：

1
static String[] SET2 = ArrayUtils.add(SET1, {"4","5","6" });

Maybe lists are easier in this case since arrays are fixed in length(by nature).如果你想静止地安装它，你可以这样做。

private static final String[] SET1 = {"1","2","3" };
private static final String[] SET2;

static
{
    List<String> set2 = new ArrayList<String>(Arrays.asList(SET1));
    set2.addAll(Arrays.asList("3","4","5"));
    SET2 = set2.toArray(new String[0]);
}

这是一个大傻瓜。

static <T> T[] concat(Class<T> clazz, T[] A, T[] B) {
    T[] C= (T[]) Array.newInstance(clazz, A.length+B.length);
    System.arraycopy(A, 0, C, 0, A.length);
    System.arraycopy(B, 0, C, A.length, B.length);
    return C;
