substring between two delimiters
I have a string like
"ABC[ This is to extract ]"
I want to extract the part "This is to extract"
in java. I am trying to use split, but it is not working the way I want. Does anyone have suggestion?
String s = "ABC[This is to extract]";
System.out.println(s);
int startIndex = s.indexOf('[');
System.out.println("indexOf([) = " + startIndex);
int endIndex = s.indexOf(']');
System.out.println("indexOf(]) = " + endIndex);
System.out.println(s.substring(startIndex + 1, endIndex));
Try as
String s = "ABC[ This is to extract ]";
Pattern p = Pattern.compile(".*\\[ *(.*) *\\].*");
Matcher m = p.matcher(s);
m.find();
String text = m.group(1);
System.out.println(text);
If there is only 1 occurrence, the answer of ivanovic is the best way I guess. But if there are many occurrences, you should use regexp:
\[(.*?)\]
this is your pattern. And in each group(1)
will get you your string.
Pattern p = Pattern.compile("\\[(.*?)\\]");
Matcher m = p.matcher(input);
while(m.find())
{
m.group(1); //is your string. do what you want
}
