[java] Java split string to array

I need help with the split() method. I have the followingString:

String values = "0|0|0|1|||0|1|0|||";

I need to put the values into an array. There are 3 possible strings: "0", "1", and ""

My problem is, when i try to use split():

String[] array = values.split("\\|"); 

My values are saved only until the last 0. Seems like the part "|||" gets trimmed. What am i doing wrong?

thanks

Consider this example:

public class StringSplit {
  public static void main(String args[]) throws Exception{
    String testString = "Real|How|To|||";
    System.out.println
       (java.util.Arrays.toString(testString.split("\\|")));
    // output : [Real, How, To]
  }
}

The result does not include the empty strings between the "|" separator. To keep the empty strings :

public class StringSplit {
  public static void main(String args[]) throws Exception{
    String testString = "Real|How|To|||";
    System.out.println
       (java.util.Arrays.toString(testString.split("\\|", -1)));
    // output : [Real, How, To, , , ]
  }
}

Try this

String[] array = values.split("\\|",-1); 

This is expected. Refer to Javadocs for split.

Splits this string around matches of the given regular expression.

This method works as if by invoking the two-argument split(java.lang.String,int) method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.
