In this post, we will learn “How to remove whitespaces in a string in Java 11?”. Java 11 introduced three new methods strip(), stripLeading() and stripTrailing() to do that.
Here, we are going to learn following things:
- What is strip(), stripLeading() and stripTrailing() methods?
- How to use them?

Let’s Begin,
1. What are strip methods?
Java 11 came up with these 3 methods as part of String class.
strip() : This method returns a string whose value is this string, with all leading and trailing white space removed.
stripLeading() : This method returns a string whose value is this string, with all leading white space removed.
stripTrailing() : This method returns a string whose value is this string, with all trailing white space removed.
2. How to use it?
Let’s take an example where we have a word ‘Techndeck’ with leading and trailing whitespaces. And, we are going to use strip methods to remove them.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | public class Strip_String_Java11 { public static void main(String[] args) { String s = " Techndeck "; //Remove all whitespaces System.out.println("String with all whitespaces removed: " + s.strip()); //"Techndeck" //Remove all leading whitespaces System.out.println("String with all leading whitespaces removed: " + s.stripLeading()); //"Techndeck " //Remove all trailing whitespaces System.out.println("String with all trailing whitespaces removed: " + s.stripTrailing()); //" Techndeck" } } |
Output:
1 2 3 | String with all whitespaces removed: Techndeck String with all leading whitespaces removed: Techndeck String with all trailing whitespaces removed: Techndeck |
