What is the Java equivalent of JavaScript\'s String.match()

I need to get an array or a list of all matches

Example:

var str = \

    Take a look at the Pattern and Matcher classes in the regex package. Specifically the Matcher.find method. That does not return an array, but you can use it in a loop to iterate through all matches.

    Your code should look something similar to this:

    String input = "The quick brown fox jumps over the lazy dog";
    Matcher matcher = Pattern.compile("e").matcher(input);
    
    while ( matcher.find() ) {
        // Do something with the matched text
        System.out.println(matcher.group(0));
    }

    String.matches(String regex) is a more direct equivalent, but only use it for one-off regexes. If you'll be using it multiple times, stick with Pattern.compile as suggested.
