try (BufferedReader br = new BufferedReader (new FileReader(“employee.txt”)))
{ // line n1
br.lines().forEach(c -> System.out.println(c)); brCopy = br; //line n2
}
brCopy.ready(); //line n3;
}
Assume that the ready method of the BufferedReader, when called on a closed BufferedReader, throws an exception, and employee.txt is accessible and contains valid text.
