Check string contains symbol questionmark“?” in Java

Question

Am using Twitter4j library to read the twitter text/tweet, more on info about it is here

Now I want to find if the tweet contains "?" in it. Am reading the text using

status.getText()

It says it returns a string, hence I tried using string.contains but somehow it doesn't work just for the "?". If I use contains to find "http" in it, it returns me true but for this "?" it doesn't always. Sample tweet is as below

I'll hit you up when I get the ps4 though ??

Someone please help me on this.

Answer 1

怎么样string.indexOf('?') >= 0 ？
