Question

Imagine you have:

String string = "A;B;;D";
String[] split = string.split(";");

I want the result to be:

split[0] = "A";
split[1] = "B";
split[2] = "";
split[3] = "D";

But the result is:

split[0] = "A";
split[1] = "B";
split[2] = "D";

Is there a simple PROPER way to to this?

Answer 1

Use the overloaded method split(String regex, int limit):

String string = "A;B;;D";
String[] split = string.split(";", -1);

From the documentation:

The string "boo:and:foo", for example, yields the following results with these parameters:

    Regex   Limit   Result
    :   2   { "boo", "and:foo" }
    :   5   { "boo", "and", "foo" }
    :   -2  { "boo", "and", "foo" }
    o   5   { "b", "", ":and:f", "", "" }
    o   -2  { "b", "", ":and:f", "", "" }
    o   0   { "b", "", ":and:f" }
