替換正則表達式組 JAVA

Question

我正在嘗試進行組替換，我不知道是否可以僅使用一個表達式

文本

String line = "[[A, _, _, _, A], [_, A, _, A, _]]";

預期文本

String line = "A _ _ _ A\n_ A _ A _";

正則表達式：([[)(,)(],)(]])

測試#1 String finalLine = line.replaceAll("(\\[\\[)(,)(],)(]])", "$1,$2,$3\n,$4");

測試#2 String finalLine = line.replaceAll("(\\[\\[)(,)(],)(]])", ",,\n,"):

測試#3 String finalLine = line..replace ( "]", "]\n" ).replace ( "[[", " " ).replaceAll ( "(])|(,)|(\\[)", "" );

Answer 1

嘗試這個：

line = line.replaceAll("],", "\n").replaceAll(",", " ").replaceAll("[\\[\\]]", "");
