Question

String.split(“*”) return Exception in Android Eclipse

Is there Any solution…

Answer 1

String#split("*") should throw an exception. String#split accepts a regular expression string, and "*" is an invalid regular expression. The * means “zero or more of the previous item” but there is no previous item.

If you’re trying to split literally on asterisks, use: split("\\*"). There are two backslashes because you need to pass a backslash to the regular expression parser to tell it that the * is literal, and of course this is in a string, so to get a backslash, you have to escape it. Hence, two.

String[] splitOnAsterisk = "one*two*three".split("\\*");
