Vector testgrades contains num_vals test scores. write a for loop that sets sumextra to the total extra credit received. full credit is 100, so anything over 100 is extra credit. ex: if testgrades = {101, 83, 107, 90}, then sumextra = 8, because 1 + 0 + 7 + 0 is 8.

import java. util. scanner;

public class sumofexcess {
public static void main (string [] args) {
final int num_vals = 4;
int[] testgrades = new int[num_vals];
int i = 0;
int sumextra = -; // initialize to 0 before your for loop

testgrades[0] = 101;
testgrades[1] = 83;
testgrades[2] = 107;
testgrades[3] = 90;

/* your solution goes here */

system. out. println("sumextra: " + sumextra);

return;
}

One subtask in the game is to roll the dice. explain why is roll the dice an abstraction.

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
