public static void main(String[ ] args) {
Scanner input = new Scanner(System.in);
try {
Formatter f = new Formatter("tasks.txt");
int count = 0;
while(count < 3) {
//your code goes here

count++;
}
f.close();
}
catch (Exception e) {
System.out.println("Error");
}
readFile();
}

public static void readFile() {
try {
File x = new File("tasks.txt");
Scanner sc = new Scanner(x);
while(sc.hasNext()) {
System.out.println(sc.next());

sc.close();

Answer 1

you must write only one generic solution wich handle all the "task" (test cases): your code will be executed once for each test case (3 test cases = code running 3 times)

Answer 2

What are the 3 tasks there..? You are not adding anything to file. So it does not output anything...
While loop doing nothing. I think you need to add count value to file in loop..
can you add description? non-pro not able see problem description..

Answer 3

for me the code below worked, but it doesn't print it on a new line and i dont know why. Maybe you guys can help me.
But the lection is solved anyway, wether the words are on a new line each or not.

//Your code goes here
String t = input.nextLine();
f.format(t, "%s", "\n");
