I have an ArrayList that I want to output completely as a String.我有一個ArrayList ，我想完全輸出爲字符串。 Essentially I want to output it in order using the toString of each element separated by tabs.本質上，我想使用由製表符分隔的每個元素的toString按順序輸出它。 Is there any fast way to do this?有沒有什麼快速的方法可以做到這一點？ You could loop through it (or remove each element) and concatenate it to a String but I think this will be very slow.您可以遍歷它（或刪除每個元素）並將其連接到一個字符串，但我認爲這會很慢。
