Java Swing JTable RowFilter忽略符号

Question

Here is my code for filtering the JTable . 'text' is the input text to search in the table.

getSorter().setRowFilter(RowFilter.regexFilter("(?i)" + Pattern.quote(text)));

Here the filtering is case insensitive. how can i ignore certain symbols like - ( ) + during the filtering like +88-11 & 8811 should match during filtering.

Answer 1

Create a custom implementation of a RowFilter . In the include method:

• Call the replaceAll() method on your string to remove the special characters that you want to exclude.
• Then search for a match to your search pattern.
• Return a true/false depending on if it matches.

Answer 2

I am assuming that you will be able to adopt the following pattern(which completely satisfies your criteria) to your required pattern:

String pattern = "([\\Q+-*/\\E]?+\\d+)+"

Simple input:

+25+36
25+36*36
2536

And similar other, which will results in exactly one match.

The way it works:

1. [\\\\Q+-*/\\\\E] is to match any one of +, -, *, / and ?+ is put afterwards as a quantifier: a X?+ means that X occurs once or not at all.
2. \\\\d+ is a pattern which matches one or more digits
3. and letting X = [\\\\Q+-*/\\\\E]?+\\\\d+ , (X) : matches X as a capture group and (X)+ means that the group will appear at least once or more.
