masya89 [10]

Answer:

Check the explanation

Explanation:

The following is a sequence of Undo — log records written by two transactions.

<START 1>; <F, A, 10>; <START U>; <U, B, 20>; <F, C, 30>; <U, D, 40>; <COMMIT U>; <T, E, 50>; <COMMIT T>; (a) < START U >;

If the system crashes after the log < START U >,

Then we have log records will be shown below.

<START U>;

<T, A, 10>;

<START T>;

SYSTEM CRASHED

The recovery manager sees the Undo - Redo log and inspect the both trans-actions T and U are not committed. Then those elements changed by both transactions are arranged to their old values.

Transaction T changes the element A.
Then the Element A is arranged to old value A=10.
Transaction U did not change any existing element in the records.
So, not anything to do with transaction U.

(B) < T, E, 50>;

If the system crashes after the log < T, E, 50>;

Then we have log records will be shown below .

START T>;

<T, A, 10>;

<START U>;

<U, B, 20>;

<T, C, 30>;

<U, D, 40>;

<COMMIT U>;

<T, E, 50>;

SYSTEM CRASHED

The recovery manager sees the Redo logs and inspect the transaction U is committed or not. Such changes made by transaction U are reached to disk.

• So much the recovery manager arranged the elements to their recent values changed by transaction U.

• Transaction U changed the elements B and its records <U, B, 20>with re-cent values.

• Transaction U changed the elements D and its records <U, D, 40>with recent values.

• The transaction T is not committed.

• Then the elements changed by transaction T are arranged to old values.

• Then element A is arranged to 10, C is arranged to 30 and E is arranged to 50.

class Main

{

// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

try{

// variables

final int CENTS_PER_POUND = 25;

final int FLAT_FEE_CENTS = 75;

// Scanner object to read input

Scanner sr=new Scanner(System.in);

System.out.print("Enter the shipping weight:");

// read the input weight

int shipWeightPounds=sr.nextInt();

// calculate total cost

int shipCostCents = (shipWeightPounds * CENTS_PER_POUND) + FLAT_FEE_CENTS;

// print Weight

System.out.println("shipping Weight: " + shipWeightPounds);

// print flat fee

System.out.println("flat fee of shipping in cents : " + FLAT_FEE_CENTS);

// print cents per round

System.out.println("Cents/pound for shipping: " + CENTS_PER_POUND);

// print cost of Shipping

System.out.println("total cost of shipping in cents: " + shipCostCents);

}catch(Exception ex){

return;}

}

}

Explanation:

Declare and initialize two constant variables "CENTS_PER_POUND=25" & "FLAT_FEE_CENTS = 75". Read the input weight from user with the help of Scanner class object. Then calculate the cost of shipping by multiply weight with cent per pound and add flat fee. Then print each of them.

Output:

Enter the shipping weight:12

shipping Weight : 12

flat fee of shipping in cents: 75

Cents/pound for shipping: 25

total cost of shipping in cents: 375
