Getting overlapping matches with multiple patterns in Java regex

Question

I have the same problem as in this link

but with multiple patterns. My regex is like:

Pattern word = Pattern.compile("([\\w]+ [\\d]+)|([\\d]+ suit         


        

Answer 1

You could try the below regex which uses positive lookahead assertion.

(?=(\b\w+ Road \d+\b)|(\b\d+ suite\b))

DEMO

String s = "XYZ Road 123 Suite";
Matcher m = Pattern.compile("(?i)(?=(\\b\\w+ Road \\d+\\b)|(\\b\\d+ suite))").matcher(s);
while(m.find())
{
    if(m.group(1) != null) System.out.println(m.group(1));
    if(m.group(2) != null) System.out.println(m.group(2));
}

Output:

XYZ Road 123
123 Suite
