I want to remove the whitespaces in a string.
Input: "le ngoc ky quang" Output: "lengockyquang" I tried the replace and replaceAll methods but that did't work.

Use the String. replace() method to remove all whitespace from a string, e.g. str. replace(/\s/g, '') . The replace() method will remove all whitespace characters by replacing them with an empty string.
To remove blank spaces from a string, Scala provides a trim() method. The trim() will remove spaces from both sides, i.e. before the characters(leading) and from the end(trailing).
What is trim() in Scala? The trim() method is used to remove all the leading and trailing spaces that are present in the string. For example, if the string looks like, " Hello World " then there is a lot of empty space before the term “Hello” and after the term “World”. The method trim() is used to remove these spaces.
In Java, we can use regex \\s+ to match whitespace characters, and replaceAll("\\s+", " ") to replace them with a single space.
Try the following:
input.replaceAll("\\s", "") If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
