usage of ...Pattern.compile()

Question

Using java.util.regex.Pattern.compile() you can specify a pattern as parameter. But how can you specify flags like case-insensitive and ignore whitespaces as well?

Answer 1

Use the overload that accepts flags.

Answer 2

You can use the Pattern.compile(String regex, int flags) method that takes flags as well, or you can put them in your Pattern itself:

Eg.

Pattern.compile("(?i)a");
