		String str = "             Here we have a string with whitespaces             ";

		// Remove leading and trailing whitespaces
		String strWithoutLeadingandTrailingSpaces = str.strip();

		// Remove all whitespaces
		String strWithoutAnySpace = str.replaceAll("\\s", "");

		System.out.println("String without Leading & Trailing spaces: "+strWithoutLeadingandTrailingSpaces);
		System.out.println("String without any space: "+strWithoutAnySpace);

The Strip() method was introduced in Java 11 and it removes leading and trailing whitespaces, while the replaceAll() method is a traditional method of removing all whitespaces from a string.

Note: ‘replaceAll()’ method uses a regular expression to match whitespaces (‘\\s’), so it will remove all types of whitespaces including spaces, tabs, and newlines.
