Question

I want to use a regular expression that extracts a substring with the following properties in Java:

1. Beginning of the substring begins with ‘WWW’
2. The end of the substring is a colon ‘:’

I have some experience in SQL with using the Like clause such as:

Select field1 from A where field2 like '%[A-Z]'

So if I were using SQL I would code:

like '%WWW%:'

How can I start this in Java?

Answer 1

   Pattern p = Pattern.compile("WWW.*:");
   Matcher m = p.matcher("zxdfefefefWWW837eghdehgfh:djf");
   while (m.find()){
       System.out.println(m.group());
   }
