How can I write this Python code in Java (parsing a string of ints, using delimiter)?

Question

Python code:

str = "123;456;789"
strlist = str.split(";")
strlist = [int("%s" % s) for s in strlist]
print strlist

Huh? The third line should be just strlist = [int(s) for s in strlist]. Even better, drop it completely and change the second line to strlist = [int(s) for s in str.split(";")]. Finally, don't use str as a variable name (it overrides the built-in name str which you probably don't want). — Tim Pietzcker

String str = "123;456;789";
String[] strList = str.split(";");

ArrayList<Integer> intList = new ArrayList<Integer>();
for (String s : strList) {
    intList.add(Integer.parseInt(s));
}

System.out.println(intList);

It would be better to create the ArrayList with the right capacity: new ArrayList<Integer>(strList.length));

System.out.println("[123, 456, 789]");
