Question

So I wrote a little section of code in a program of mine that uses the split method to parse out and sort the individual components held within a string. Below is a sample of the code:

String[] sArray;

String delimiter = "*";

String test = "TEXT*TEXT*TEXT*";
String a = "";
String b = "";
String c = "";

sArray= test.split(delimiter);

a = sArray[0];
b = sArray[1];
c = sArray[2];

System.out.println("A is: " + a + "\nB is: " + b + "\nC is: " + c);

However, when I run this program, it returns an error stating that:

Dangling meta character '*' near index 0

So I googled this error and found it might be related to an issue with how * can be considered a wildcard character in regex. So I tried:

String delimiter = "\*"

But that just returned another error stating:

illegal escape character

Has anyone ran into this issue before or know how you are (if you are) supposed to escape * in java?

Answer 1

You also have to escape the backslash:

String delimiter = "\\*";

Because the string literal "\\" is just a single backslash, so the string literal "\\*" represents an escaped asterisk.
