I have some String like this:
"this is a string like #{aa} and#{bb}. "
"#{cc}this is another str#{dd}ing..."
I want to change these String like this:
"this is a string like ? and?." "aa" "bb"
"?this is another str?ing..." "cc" "dd"
I tried to use regular expressions to split these string and failed.
What should I do?
You can replace the string using a regex like this:
#\{(.*?)\}
Then you have to grab the content from the capturing group and concatenate it to your string. I leave the logic for you :)
You can try like this:
final String regex = "#\\{(.*?)\\}";
final String string = "ere is some string #{sx} and #{sy}.";
final String subst = "?";
final Pattern pattern = Pattern.compile(regex);
final Matcher matcher = pattern.matcher(string);
while (matcher.find()) {
System.out.print(matcher.group(1) + " ");
}
final String result = matcher.replaceAll(subst);
System.out.println(result);
