如何连接静态字符串数组 [英] How do I concatenate static string arrays

问题描述

可能重复：

如何在Java中连接两个数组？

我将SET1声明为静态String []，我想将SET2声明为SET1 +其他几个参数。是否可以将SET2静态相似（即私有静态String []）声明为SET1，但使用上面的定义，如果不是如何做到这一点？

I have SET1 declared as a static String[] and I would like to declare SET2 as SET1 + few other parameters. Is it possible to declare SET2 statically similar (i.e. private static String[]) to SET1 but using the above definition, if not how to do this?

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

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

推荐答案

看看 Commons Util ArrayUtils.add：

Look at Commons Util ArrayUtils.add:

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