post	Java Program To Remove All Whitespaces From The Given String.	gaurav	String Java Programs	false	In this tutorial, we will see how to remove all whitespaces from the given String.

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.

Java Program

/**
 * A Java program to remove all the whitespaces from the given string.
 * By coderolls.com
 */
public class RemoveWhitespaces {

  public static void main(String[] args) {
  
    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);
  }
}

Output

The example String is given below: 
It is an example string.

The example String after removing all the whitespaces is as given below: 
Itisanexamplestring.
