Java – Split and trim in one shot

Use regular expression \s*,\s* for splitting.

String result[] = attributes.split("\\s*,\\s*");

For Initial and Trailing Whitespaces
The previous solution still leaves initial and trailing white-spaces. So if we’re expecting any of them, then we can use the following solution to remove the same:

String result[] = attributes.trim().split("\\s*,\\s*");

Using java 8 you can do it like this in one line

String[] result = Arrays.stream(attributes.split(",")).map(String::trim).toArray(String[]::new);

You can do it with Google Guava library this way :

List<String> results = Splitter.on(",").trimResults().splitToList(attributes);

which I find quite elegant as the code is very explicit in what it does when you read it.

// given input
String attributes = " foo boo, faa baa, fii bii,";

// desired output
String[] result = {"foo boo", "faa baa", "fii bii"};

This should work:

String[] s = attributes.trim().split("[,]");

As answered by @Raman Sahasi:

before you split your string, you can trim the trailing and leading spaces. I’ve used the delimiter , as it was your only delimiter in your string
