這是我的問題：我想以非常清晰易讀的方式創建一個數組，以便讀者能夠立即知道數組的元素。當數組固定后，就很容易也很清楚了：    String[] columns = new String[] { "unit", "file_row", "unit_row", "content" };    String[] types = new String[] { "INTEGER", "INTEGER", "INTEGER", "TEXT" };但我也有變量數組，具體取決于參數：    // Is an argument of my method, containing the variable elements of the future array    String[] method_arg = new String[] {"key1", "key2"};    // The clear and readable way doesn't work anymore    String[] columns = new String[] { "unit", method_arg, "hash"};    String[] types = new String[] { "INTEGER", method_arg_types, "INTEGER"};    // And the ways that work are ... much less readable    String[] columns = new String[] {"unit"};    columns = Stream.concat(Arrays.stream(columns), Arrays.stream(method_arg)).toArray(String[]::new);    columns = Stream.concat(Arrays.stream(columns), Arrays.stream(new String[] {"hash"})).toArray(String[]::new);    // Awkward    String[] types = new String[method_arg.length + 2];    Arrays.fill(types, "TEXT");    types[0] = "INTEGER";如何使代碼保持清晰易讀？代碼相當靈活，使用列表應該不是問題，但我寧愿避免使用非標準庫。另外，我知道一個解決方案是創建一個方法來創建這些數組，例如    join_arrays(new String[] {"unit"}, method_arg, new String[] {"hash"});但如果有解決方案使代碼清晰并避免創建專用函數，那就更好了。如果沒有，我將求助于這個選項。感謝您有一個愉快的一天 ！
