Thread: Can scanner read the specified line?

Hello ice,

The problem with the Scanner is, as soon as the user presses enter, it takes that as the input.
There isn't a way to move to the next line without pressing enter.

This is assuming you are taking user input from the console though.
If you were reading in a file with the Scanner class, this wouldn't be a problem.

You could possibly do something like this. As an example, it will take in user input and print out the 10th line.

import java.util.Scanner;
 
public class ScannerTest {
 
	/**
	 * JavaProgrammingForums.com
	 */
	public static void main(String[] args) {
 
		Scanner sc = new Scanner(System.in);
		System.out.println("Enter something:");
 
		int count = 1;
 
		while (sc.hasNext()) {
			String ignore = sc.nextLine();
			count++;
			if (count == 10) {
				String keep = sc.nextLine();
				System.out.println("This is the 10th line: " + keep);
				break;
			}
		}
	}
}

Thank you so much JavaPF!! ..especially the example you provided.

If you were reading in a file with the Scanner class, this wouldn't be a problem.

, you mean Scanner can read the specified line from a file? If so, then how to do that?

He posted a great way to do it. What he meant was, with a file, you don't have to wait for the user to press enter.

No problem. So did you get it all figured out?

Glad I could help.
