Input Loop

You don't have to have five statements each using scan.nextLine(). You can use a loop to execute it the required number of times. Here is a program that reads and echos the first five lines of a file:

import java.util.Scanner;

class MultiEcho
{
  public static void main ( String[] args ) 
  {
    String line;
    Scanner scan = new Scanner( System.in );
 
    int count = 1;
    while ( count <= 5 )
    { 
      System.out.println("Enter line" + count + ": ");
      line = scan.nextLine();
      System.out.println( "You typed: " + line );
      count = count + 1;
    }
  }
}

Here is the program working with an input file:

C:\users\default\JavaLessons>java MultiEcho < input.txt
Enter line1:
You typed: This is line one,
Enter line2:
You typed: this is line two,
Enter line3:
You typed: this is line three,
Enter line4:
You typed: this is line, uh... four,
Enter line5:
You typed: and this is the last line.
