They are probably looking for B. subscribing to journals is a good way of keeping up with what's happening in any field.
Of course, a very carefully curated professional network online is great for this too (but they said "personal" so that's not the answer)
Employers generally prefer that employees WORK as often as possible, so even though JUDICIOUS use of social media is a great way to keep current, D isn't the answer either.
Blogging about personal experiences is not necessarily going to teach you anything about work, though blogging professionally can be useful in gathering response from your readership
Answer:
import java.io.*;
public class Main {
public static void main(String[] args) throws IOException {
BufferedReader brObject = new BufferedReader(new InputStreamReader(System.in));
String str;
while ((str = brObject.readLine()) != null) {
int number = Integer.parseInt(str);
System.out.println(number * number);
}
}
}
Explanation:
- Inside the main method, create an object of BufferedReader class to read lines from standard input.
- Declare a string and run a while loop until it reaches the end of the input.
- Inside the while loop convert the string into an integer data type.
- Finally display the output by squaring the number.

Explanation:
Separating this critical section into two sections:
void transaction(Account from, Account to, double amount)
{
Semaphore lock1, lock2;
lock1 = getLock(from);
lock2 = getLock(to);
wait(lock1);
withdraw(from, amount);
signal(lock1);
wait(lock2);
deposit(to, amount);
signal(lock2);
}
will be the best solution in the real world, because separating this critical section doesn't lead to any unwanted state between them (that is, there will never be a situation, where there is more money withdrawn, than it is possible).
The simple solution to leave the critical section in one piece, is to ensure that lock order is the same in all transactions. In this case you can sort the locks and choose the smaller one for locking first.
You can format the columns for a certain width or you can use format cells, word wrap.
