Consider the code fragment below (with nested loops). int sum = 0;for (int i = 1; i < 5; i++) for (int j = 1; j <= i; j++)

sammy [17]

Answer:

Option d is the correct answer for the above question.

Explanation:

The first loop of the program has a second loop and then the statement. In this scenario, the second loop executes for the value of the first loop and the statement executes for the value of the second loop.
The first loop executes 4 times, Then the second loop or inner loop executes n times for the n iteration of the first loop, for example, 1 time for the first iteration of the first loop, 2 times for the second iteration of the first loop and so on.
Then the inner loop executes (1+2+3+4) iteration which gives the result 10 iterations.
The sum initial value is 0 and the "sum++", increase the value of the sum by 1.
So the value of the sum becomes 10 after completing 10 iterations of the inner for loop.
Hence the 10 will be the output. So the Option d is the correct answer while the other is not.

Consider the following code snippet:public static void main(String[] args) throws FileNotFoundExceptionWhich of the following st

iVinArrow [24]

Answer:

The main method should simply terminate if the FileNotFoundException occurs.

Explanation:

Considering the full code snippet

snippet:public static void main(String[] args) throws FileNotFoundException

public static void main(String[])

represent the entry point method to a java main method

The addition of

throws FileNotFoundException

widens the scope of the main method to explicitly specifies that an exception named the FileNotFoundException may be thrown.

So, if any part of the code explicitly throws the FileNotFoundException the compiler makes use of this to throw an exception.

By throwing an exception, the main method is not catching any exceptions, instead it handles the FileNotFoundException by throwing it to the source which invoked the main method

This is required by the compiler to terminate the program if the FileNotFoundException occurs.

What are the uses of DVD Ram

Verdich [7]

Answer:

Like ordinary random access memory (RAM), it can be repeatedly read, written to, and erased. Intended mostly for removable computer storage, DVD-RAM provides the capabilities of Rewriteable CD (CD-RW) - users can run programs from the discs, copy files to them and rewrite or delete them.

Determine the best access modifier for each of the following situations: a. A class Employee records the name, address, salary,

Lorico [155]

Answer:

a. Protected

b. Public

Explanation:

There are four acess modifier in Java.

Default: Acessible only within the same package.

Public: Can be acessed by any class.

Private: Acessible only within the class.

For example, you have a class employee and a private method. This method can only be accessed by an object that is an instance of an employee.

Protected: Used in classes that extend each other. For example, a class of employees would extend employee.

So:

a. A class Employee records the name, address, salary, and phone number.

The best acesses modifier is protected. A class may extended employee but have the same arguments(name, adress, salary, phone number), so it should also have acess to the method.

b. An adding method inside of a class BasicMath.

This method can be used in a variety of packages and projects and classes... and there is no important information regarding security. So the best method is public.
