Use String.split() with multiple delimiters

Question

I need to split a string base on delimiter - and .. Below are my desired output.

AA.BB-CC-DD.zip ->

AA
BB
CC
DD
zip 

but my following code does not work.

private void getId(String pdfName){
    String[]tokens = pdfName.split("-\\.");
}

Answer 1

I think you need to include the regex OR operator:

String[]tokens = pdfName.split("-|\\.");

What you have will match:
[DASH followed by DOT together] -.
not
[DASH or DOT any of them] - or .

Answer 2

Try this regex "[-.]+". The + after treats consecutive delimiter chars as one. Remove plus if you do not want this.

Answer 3

You can use the regex "\W".This matches any non-word character.The required line would be:

String[] tokens=pdfName.split("\\W");

Answer 4

Using Guava you could do this:

Iterable<String> tokens = Splitter.on(CharMatcher.anyOf("-.")).split(pdfName);

Answer 5

The string you give split is the string form of a regular expression, so:

private void getId(String pdfName){
    String[]tokens = pdfName.split("[\\-.]");
}

That means to split on any character in the [] (we have to escape - with a backslash because it's special inside []; and of course we have to escape the backslash because this is a string). (Conversely, . is normally special but isn't special inside [].)

Answer 6

For two char sequence as delimeters "AND" and "OR" this should be worked. Don't forget to trim while using.

 String text ="ISTANBUL AND NEW YORK AND PARIS OR TOKYO AND MOSCOW";
 String[] cities = text.split("AND|OR"); 

Result : cities = {"ISTANBUL ", " NEW YORK ", " PARIS ", " TOKYO ", " MOSCOW"}

Answer 7

I'd use Apache Commons:

import org.apache.commons.lang3.StringUtils;

private void getId(String pdfName){
    String[] tokens = StringUtils.split(pdfName, "-.");
}

It'll split on any of the specified separators, as opposed to StringUtils.splitByWholeSeparator(str, separator) which uses the complete string as a separator

Answer 8

String[] token=s.split("[.-]");

Answer 9

It's better to use something like this:

s.split("[\\s\\-\\.\\'\\?\\,\\_\\@]+");

Have added a few other characters as sample. This is the safest way to use, because the way . and ' is treated.

Answer 10

pdfName.split("[.-]+");

• [.-] -> any one of the . or - can be used as delimiter

• + sign signifies that if the aforementioned delimiters occur consecutively we should treat it as one.

Answer 11

You may also specified regular expression as argument in split() method ..see below example....

private void getId(String pdfName){
String[]tokens = pdfName.split("-|\\.");
}

Answer 12

Try this code:

var string = 'AA.BB-CC-DD.zip';
array = string.split(/[,.]/);

Answer 13

s.trim().split("[\\W]+") 

should work.

Answer 14

If you know the sting will always be in the same format, first split the string based on . and store the string at the first index in a variable. Then split the string in the second index based on - and store indexes 0, 1 and 2. Finally, split index 2 of the previous array based on . and you should have obtained all of the relevant fields.

Refer to the following snippet:

String[] tmp = pdfName.split(".");
String val1 = tmp[0];
tmp = tmp[1].split("-");
String val2 = tmp[0];
...
