Use string contains for multiple checks

Hi everyone

I wanted to know wether is possible to use the contains method to check multiple values.

For example:

If I want to know wether a string contains a "?" or "!". How would I change the syntax to accomodate both?

I am currenly using this : value.contains("?"); but I want to be able to put multiple characters check.

Thank you

You could use:

Code:

---

if ( value.contains("?") || value.contains("!") ) {...}

---

Or you could use a regex Matcher.

I was aware of that syntax where I can use "||" or "&&" to add multiple values but it's not neat and effective when you want to check multiple values as your repeating the same line of code again and again.

I never came accross a regex matcher, can you provide an example of how that would work with the two symbols I've mentioned?

Thank you

Something like this should work:

Code:

---

Pattern p = Pattern.compile("[?!]");
Matcher m = p.matcher(value);

if (m.find()) {
        System.out.println("value = " + value + " matches");
}
else {
        System.out.println("value = " + value + " does NOT match");
}

---

Another solution could be:

Code:

---

if (value.matches(".*[?!].*")) {
        System.out.println("value = " + value + " matches");
}
else {
        System.out.println("value = " + value + " does NOT match");
}

Albert.
