Groovy and Java are different languages. For groovy, see this question: groovy sort with comparator syntax

Consider this groovysh (Groovy shell) session:

groovy:000> x = ["a;b;c","d;e", "f;g;h;i", "j"]
===> [a;b;c, d;e, f;g;h;i, j]
groovy:000> x.sort{x,y -> x.split(";").length <=> y.split(";").length}
===> [j, d;e, a;b;c, f;g;h;i]
