{

try

{

totalIncome += inputFile.nextDouble();

}

catch(InputMismatchException e)

{

System.out.println("Non-numeric data encountered " +

"in the file.");

inputFile.nextLine();

}

finally

{

totalIncome = 35.5;

}

}

What will be the value of totalIncome after the following values are read from the file?

2.5

8.5

3.0

5.5

abc

1.0

A) 35.5 B) 75.0 C) 0.0 D) 19.5

catch (NumberFormatException e)

{

System.out.println(str + " is not a number.");

}

A) Because you can have only one catch clause in a try statement.

B) Because the Integer.parseInt method does not throw a NumberFormatException.

C) Because the Integer.parseInt method does not throw an IllegalArgumentException.

D) Because NumberFormatException inherits from IllegalArgumentException. The code should handle NumberFormatException before IllegalArgumentException.

please just prove the correct answer without explaination. thank you
