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 {
RandomAccessFile raf =
new RandomAccessFile("test.dat", "r");
int i = raf.readInt();
}
catch(IOException ex) {
System.out.println("IO exception");
}
}
}

◦ The program compiles and runs fine, but nothing is displayed on the console.
◦ 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 raf is not created correctly.
◦ The program does not compile because readInt() is not implemented in RandomAccessFile.
