Given that data.txt and alldata.txt are accessible, and the code fragment:

What is required at line n1 to enable the code to overwrite alldata.txt with data.txt?

Given:

and the code fragment:

What is the result?

Given the code fragment:

What is the result?

Given the code fragment:
public static void main (String[] args) throws IOException {
BufferedReader brCopy = null;
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.
What is the result?

Given the code fragment:

What is the result?
Word: why what when
