Question
![Consider the below java code:
import java.io.*;
public class Main {
public static void main(String[] args) {
int values[] = { 20, 30, 40, 60, 70, 80, 90, 100);
try (Random AccessFile file = new RandomAccessFile("integersText.dat", "w")) {
int k
for (int i = 0; i < values.length; i++) {
file.writeInt(values[i]);
}
file.seek (0) /
k file.readInt ();
System.out.println (k),
file.seek (4);
k file.readInt ();
System.out.println (k);
for (int i = 0; i < values.length; i+2) {
file.seek (8 * 1);
k file.readInt ();
System.out.printf("%d", k);
}
System.out.println();
} catch (IOException e) {
System.out.println("An IO Exception is caught!");
} finally (
System.out.println("File access done successfully.");
}
When the above code is executed, what output is generated?](https://content.bartleby.com/qna-images/question/306fbe62-d873-4d3c-bd0d-f543b714cd0c/1323ab47-a7cd-4369-8bde-9a6ff7f02df6/aiqas6b_thumbnail.png)
