Java 11 - strip(), stripLeading() and stripTrailing() example

Java 11 added a few useful APIs to the commonly used String class.  In this post, we will see the usage of below String methods with an example.
  • String java.lang.String.strip() - The strip() instance method returns a string with all leading and trailing whitespaces removed.
  • String java.lang.String.stripLeading() - This method returns a string with all leading white space removed.
  • String java.lang.String.stripTrailing() - This method returns a string with all trailing white space removed.
