You can use the regular expression \s to check if your text consists of any whitespace. In Java, you can easily use the String class's matches() method to check if the text contains any whitespace. For example, you can use the following code: ```java String text = "This is a sample text with whitespace"; if (text.matches(".*\\s.*")) { System.out.println("Text contains whitespace"); } else { System.out.println("Text does not contain whitespace"); } ``` This will check if the text contains any whitespace and print the appropriate message. **
