I'm trying to do a group replacement, I don't know if it's possible to do with just one expression
Text
String line = "[[A, _, _, _, A], [_, A, _, A, _]]";
Expected text
String line = "A _ _ _ A\n_ A _ A _";
Regex : ([[)(,)(],)(]])
Test #1 String finalLine = line.replaceAll("(\\[\\[)(,)(],)(]])", "$1,$2,$3\n,$4");
Test #2 String finalLine = line.replaceAll("(\\[\\[)(,)(],)(]])", ",,\n,"):
Test #3 String finalLine = line..replace ( "]", "]\n" ).replace ( "[[", " " ).replaceAll ( "(])|(,)|(\\[)", "" );
Try this:
line = line.replaceAll("],", "\n").replaceAll(",", " ").replaceAll("[\\[\\]]", "");
