Matcher not finding overlapping words?

Question

I\'m trying to take a string:

String s = \"This is a String!\";

And return all 2-word pairs within that string. Namely:

{\"this         


        

Answer 1

I tried with group of pattern.

String s = "this is a String";

Pattern pat = Pattern.compile("([^ ]+)( )([^ ]+)");
Matcher mat = pat.matcher(s);
boolean check = mat.find();
while(check){
    System.out.println(mat.group());
    check = matPOS.find(mat.start(3));
}

from the pattern ([^ ]+)( )([^ ]+)
...........................|_______________|
..................................group(0)
..........................|([^ ]+)| <--group(1)
......................................|( )| <--group(2)
............................................|([^ ]+)| <--group(3)
