Question

I want to check whether string contains particular sub string and using CONTAINS() for it.

But here problem is with space.

Ex- str1= “c not in(5,6)”

I want to check whether str contains NOT IN so I am using str.contains(“not in”)..

But problem is that here space between NOT and IN is not decided i.e. there can be 5 spaces also..

How to solve that I can find sub string like not in with any no of spaces in between…

Answer 1

You should use a regex: "not\\s+in"

    String s = "c not  in(5,6)";
    Matcher matcher = Pattern.compile("not\\s+in").matcher(s);
    System.out.println(matcher.find());

Explanation: The \\s+ means any kind of white space [tab is also acceptable], and must repeat at least one [any number >=1 will be accepted].

If you want only spaces, without tabs change your regex to "not +in"
