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

Question

```
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");
}
}
}```
a. The program does not compile because raf is not created correctly.
b. The program does not compile because readInt() is not implemented in RandomAccessFile.
c. The program compiles, but throws IOException because the file test.dat doesn't exist. The program displays IO exception.
d. The program compiles and runs fine, but nothing is displayed on the console.

Answer 1

c The problem is in line: new RandomAccessFile("test.dat", "r"); Because the file does not exist, you cannot open it for reading.
