Learn about Java metacharacters.
- [Presenter] The Java doc for the pattern class…contains an exhaustive listing of the…metacharacters available within the class.…If you scroll down, you can find these characters.…This is a more succinct list of the metacharacters…that are available within Java.…Let's begin by examining metacharacters…and starting with a pattern,…country dot pattern.…I'm pressing the CTRL key,…and I'm navigating to sample patterns.…Country dot string contains the string literal…C-O-U-N and the metacharacter dot.…
Let's run this test.…We find out that C-O-U-N-T, as in country,…started at Index 75.…Next, we will examine our first character construct;…square brackets that contain one or more characters.…Implicitly, this construct uses an or operation.…If the string that you are searching,…contains any of the characters…then the fine myth of the method object will return true.…
In other words,…if the first character is found…or the second character is found…or any subsequent character is found,…the fine method will return true.…Let's demonstrate this using the following pattern:…
