Question

I’m trying to get Java’s scanner to keep accepting input until the user types some variation of “end,” like, “END”, “eNd”, “eND”, etc.

However, due to my limited experience with Scanner, I can’t think of code that would work for all variations of “end”. Here’s what I have so far:

private static Scanner userInput = new Scanner(System.in);
String textBody = "";

while(!userInput.hasNext("end") && !userInput.hasNext("END"))
{
textBody +=  userInput.nextLine() + "\n";
}

Thanks for any help

Answer 1

If you want to terminate the loop when the user enters a line that consists of “end” (in some variation of capitals, but not terminate when the user enters “end of the road”, then try something like this:

private static Scanner userInput = new Scanner(System.in);
StringBuilder sb = new StringBuilder();

String line = userInput.nextLine();
while(!line.equalsIgnoreCase("end"))
{
    sb.append(line).append('\n');
    line = userInput.nextLine();
}

String textBody = sb.toString();

(You could write this as a for loop equally well.)
