Parse multiple doubles from a String

Question

I would like to know how to parse several double numbers from a string, but string can be mixed, for instance: String s = \"text 3.454 sometext5.567568more_text\"

Answer 1

1. Parse out the substring (surrounded by whitespace)

2. Use String.ParseDouble() to get the numeric value

Here's one example, using "split()" to parse (there are many alternatives):

String phrase = "the music made   it   hard      to        concentrate";
String delims = "[ ]+";
String[] tokens = phrase.split(delims);

Here's a second alternative:
