What happens if the file test.dat does not exist when you attempt to compile and run the following code?

import java.io.*;
class Test {
public static void main(String[ ] args) {
try {
BufferedReader infile = new BufferedReader(new FileReader("test.dat"));
String mytext = infile.readLine();
}
catch(IOException ex) {
System.out.println("IO exception");
}
}
}
The program compiles, but throws IOException because the file test.dat doesn't exist. The program displays IO exception.

The program does not compile because infile is not created correctly.

The program does not compile because readLine() is not implemented in BufferedReader.

The program compiles and runs fine, but nothing is displayed on the console.
