I got a String from a .csv and want to split it:
String line = "1,2,3,,,,false,true,,,false,false,,,,,,,,,,,,";
String data[] = line.split(",");
This is the result of the array:
data[0] - "1"
data[1] - "2"
data[2] - "3"
data[3] - ""
data[4] - ""
data[5] - ""
data[6] - "false"
data[7] - "true"
data[8] - ""
data[9] - ""
data[10] - "false"
data[11] - "false"
Why are the last "" lines cutted away from the array?
Use the -1 parameter
String data[] = line.split(",", -1);
Check the javadoc
"The limit parameter controls the number of times the pattern is applied and therefore affects the length of the resulting array. If the limit n is greater than zero then the pattern will be applied at most n - 1 times, the array's length will be no greater than n, and the array's last entry will contain all input beyond the last matched delimiter. If n is non-positive then the pattern will be applied as many times as possible and the array can have any length. If n is zero then the pattern will be applied as many times as possible, the array can have any length, and trailing empty strings will be discarded. "
When you specify no argument calling public String[] split(String regex) it uses default as 0.
From javadoc: "This method works as if by invoking the two-argument split method with the given expression and a limit argument of zero."
https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#split(java.lang.String)
the API says "Trailing empty strings are therefore not included in the resulting array."
