Read input line by line

How do I read input line by line in Java? I searched and so far I have this:

import java.util.Scanner;

public class MatrixReader {
    public static void main(S

Ideally you should add a final println() because by default System.out uses a PrintStream that only flushes when a newline is sent. See When/why to call System.out.flush() in Java

while (input.hasNext()) {
    System.out.print(input.nextLine());
}
System.out.println();

Although there are possible other reasons for your issue.
