public static String[] stringArray = new String[size]; // give some "size"
OR
或者

To initialise an array at construction time you can specify a list values in curly braces:
要在构造时初始化数组，您可以在花括号中指定列表值：
private static final String[] STRING_ARRAY = {"foo", "bar", "baz"};
In my example I have assumed that you won't want to change the instance of array and so have declared it final. You still would be able to update individual entries like so:
在我的示例中，我假设您不想更改数组的实例，因此已声明它final。您仍然可以像这样更新单个条目：
array[0] = "1";
But you won't be able to replace the array with a different one completely. If the values are going to change a lot - especially if the number of values are going to change - then it may be worth considering using Listinstead.
但是您将无法完全用不同的阵列替换阵列。如果值会发生很大变化 - 特别是如果值的数量会发生变化 - 那么可能值得考虑使用它List。
