Splitter trimResults() method | Guava | Java

Last Updated : 31 Jan, 2019
The method trimResults() returns a splitter that behaves equivalently to this splitter, but automatically removes leading and trailing whitespace from each returned substring. For example, Splitter.on(', ').trimResults().split(" a, b, c ") returns an iterable containing ["a", "b", "c"]. Syntax: 
public Splitter trimResults()
Return Value: This method returns a splitter with the desired configuration. Example 1: Java 
// Java code to show implementation of
// trimResults() method
// of Guava's Splitter Class

import com.google.common.base.Splitter;
import java.util.List;

class GFG {

    // Driver's code
    public static void main(String[] args)
    {

        // Creating a string variable
        String str = "Hello,  geeks, for,  geeks,  noida";

        // Using trimResults() method. Strings that
        // have been split apart often need to be
        // trimmed. They often have surrounding whitespace.
        // With trimResults(), Splitter does this.
        List<String> myList = Splitter.on(',')
          .trimResults().splitToList(str);

        for (String temp : myList) {
            System.out.println(temp);
        }
    }
}
Output: 
Hello
geeks
for
geeks
noida
