Scroll down for the full source.\u00a0 Today, to execute code asynchronously in JavaFX, the background code must be written in Java.\u00a0 Ideally, your Java code will return JavaFX data types, keeping your FX code clean and helping you be prepared for the day when you won’t need Java.<\/p>\n

This is how you can create and return JavaFX sequences from your Java code.<\/p>\n

Set the return type of your method to com.sun.javafx.runtime.sequence.Sequence<\/strong>.\u00a0 Many of the com.sun.javafx classes seem to have been created for use in Java code.<\/p>\n

<\/a>Code block<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
@Override\npublic<\/span> Sequence<<\/span>String><\/span> call(<\/span>)<\/span> throws<\/span> Exception<\/span><\/a> {<\/span><\/pre><\/div><\/div>\n
In your code, use any type of collection class you like.\u00a0 It’s easiest to use List classes, though, because they can be directly converted.<\/p>\n
<\/a>Code block<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
List<<\/span>String><\/span> names =<\/span> Arrays<\/span><\/a>.asList<\/span>(<\/span>"Arthur"<\/span>, "Trillian"<\/span>, "Zaphod"<\/span>)<\/span>;<\/span><\/pre><\/div><\/div>\n
Then, convert the list to a sequence using com.sun.javafx.runtime.sequence.Sequences<\/strong> and return it.<\/p>\n

Here it is all together for impatient people like me.<\/p>\n
