    Default help with bookfinder programme

    hi, i'm trying to write a program that reads lines of text. if any line that contains the word "book" it will print the line, but replace the word "book" with [printed pages]s.

    at the moment my code prints the first line of text regardless of whether it contains the word "book"

    any help would be greatly apprec iated


    import java.util.Scanner;
     
    public class BookFinder {
     
      public static void main(String[] args) {
     
                     Scanner scan = new Scanner(System.in);
     
            String fname, description, suffix;
     
            boolean t = true;
            System.out.println("Enter lines of text - finish with \"end\" :");
            do {
     
                description = scan.nextLine();
                if(description.contains("end"))
                {
                    return;
                }
    description=description.replaceFirst("[Bb]ook", "printed pages");
     
    System.out.println(description);
     
        }while(t==true);
        }
    }

    Do you only want it to print if the String contains book? If so, this is how I would do it.
    import java.util.Scanner;
     
    public class BotMain {
    	public static void main(String[] args)
    	{
    		Scanner scan = new Scanner(System.in);
    		String fname, description, suffix;
     
    		System.out.println("Enter lines of text - finish with \"end\" :");
     
    		while(true)
    		{
    			description = scan.nextLine();
     
    			if (description.contains("exit"))
    				break;
     
    			else if (description.contains("book"))
    			    System.out.println((description = description.replaceFirst("[Bb]ook", "Printed pages")));
    		}
    	}
    }

    thank you very much that worked amazing, wondering if could pick your brain on one more topic

    how would i go about getting the programme to recognise higher case "B" as well as the lower case. when the word "book" is entered on a line.
