Convert String to array of integer in java

Question

Outline how a Java program could convert a string such as “1,2,3,4,5” into an array ({1, 2, 3, 4,5})

Answer 1

With Guava you can do this in one line:

int[] array = Ints.toArray(Lists.newArrayList(Ints.stringConverter().convertAll(Splitter.on(",").split("1,2,3,4,5"))));

or so (if you don't require an array):

Iterable ints = Ints.stringConverter().convertAll(Splitter.on(",").split("1,2,3,4,5"));
