How do I remove a word that contains a dash from a text?

so I want to remove a word that contains a dash between them like off-campus alongside other things that I want to remove. here is my code so far.

Scanner read = new Scanner(System.in);

String text;
//text: CS 204 is a wonderful class. So WONDERFUL ! amazing class. cleaver class. must-remove
System.out.print("Please Enter Text: ");
text = read.nextLine();
System.out.println(text);
String n = text.replaceAll("[\\.\\!\\d]", "");
System.out.println(n);

so far it prints

CS is a wonderful class So WONDERFUL amazing class cleaver class must-remove

Solution

  • You could use the regex \w+-\w+, which means 2 words \w+, separated by a dash, and you use

    "CS 204 is a wonderful class. So WONDERFUL ! must-remove".replaceAll("\\w+-\\w+", "") 
// CS 204 is a wonderful class. So WONDERFUL !
