Remove whitespaces from all over the String
We can replace all whitespaces with empty string using `String.replaceAll() method.
The replace all methods accept regex string and replacement string as input params. And return the replaced string.
We can use the "\\s+" regex expression to find all the whitespaces from the given input string.

String exampleString = "It is an example string.";
System.out.println("The example String is as given below: ");
System.out.println(exampleString);
//Remove all whitespaces from the example string
String stringWithoutWhitespaces = exampleString.replaceAll("\\s+", "");
System.out.println("\nThe example String after removing all the whitespaces is as given below: ");
System.out.println(stringWithoutWhitespaces);
}
}
