motikmotik

This question is incomplete because the options are missing; here are the options for this question:

Which of the following is the most effective way for Velma to save money each month?

A. Automatically reroute a portion of her paycheck to her savings account.

B. Manually deposit 10% of her paycheck in her savings account.

C. Pay all of her bills and then place the remaining money in her savings account.

D. Pay all of her bills and then place the remaining money in her piggy bank.

The correct answer to this question is A. Automatically reroute a portion of her paycheck to her savings account.

Explanation:

In this case, Velma needs to consistently save money for her vacation as this guarantees she will have the money for the trip. This means it is ideal every month she contributes consistently to her savings for the vacation.

This can be better be achieved by automatically rerouting a part of her paycheck for this purpose (Option A) because in this way, every month the money for the vacations will increase and the amount of money will be consistent, which means Velma will know beforehand the money she will have for the vacation. Moreover, options such as using a piggy bank or paying the bills and using the rest for her savings, do not guarantee she will contribute to the savings every month, or she will have the money she needs at the end.

Insert XXX to output the student's ID. public class Student { private double myGPA; private int myID; public getID) { return myI
Aleonysh [2.5K]

Answer:

Explanation:

The question above is missing many details and are actually various questions in one. I will answer each one seperately below...

A. The piece of code to get the ID in this code snippet that needs to replace XXX would be the following ... System.out.println("Student ID: " + s.getID());

B. A static main() can declare and create objects. Once these objects are created their instance methods can then be called.

C. Integer score1 = 72;

    int score2 = 85;

    Character grade = 'C';

     In the above code snippet, the information stored in score1, score2, and grade are the following... obj reference, 85, obj reference. This is becasue both Integer and Character are classes and the values being passed to their variables are referencing that object class, while score2 is a primitive type of int and is therefore simply a number.

D. The statement that is true is ... Contents of a Double instance can be modified after initialization. Objects can be modified by calling its setter methods after initializing it.
