String split

[sankari subash]

Hi,

i have a string 1;2;3;;;4;;;
i want to split the string and put it in a list [1,2,3,,,4,,]

But while using the split method i found that the trailing blanks are eliminated.. please tell a solution for this

You can do that with the "String.split(String regex,int limit)" method by using a negative value for the limit parameter.

HI,

Even you can try out using replace method...it works
FYI:
str = str.replace(";", ",");

[Nalaka Gamage]

public class Test1 {
public static void main(String[] args) {
String aa = "1;2;3;;;4;;;";
String bb = aa.replace(';',',');
String[] cc = bb.split(";");
java.util.List dd = Arrays.asList(cc);
System.out.println(dd);
}
}

Output:[1,2,3,,,4,,,]

int limit = -1;
String[] cc = aa.split(";", limit);

Or limit should be the length of the reslut(slots) you want.

Read more in the API(look for the split method:

hi,
i'm not able to understand the program

when
String bb = aa.replace(';',',');
this happens, there is no such pattern as ';' in the string bb

so how can we split it based on this

String[] cc = bb.split(";");

and its working fine...

any light on this.

Actually, it doesn't work. What is happening is that you simply changed the delimiter to a comma, which is the separator used by the List toString() method.

So you have one element that happens to have commas, and not nine elements, that is separated by commas.
