# Project #1696 - java programming

THERE ARE 3 PROBLEMS TOTAL. THANK YOU.

PROBLEM 1 (3.109)

One day soon, the US government will finally decide to do away with pennies, as they currently cost more than a penny to produce. Complete the program below so that it prompts the user for a price in dollars and cents, determines the cents portion of the price to the nearest dime, and prints the revised price.

For example, if a price was \$32.56, the revised price would be \$32.60. However, if a price was \$23.34, the revised price would be \$23.30.

Complete the following code:

import java.util.Scanner;

/**

This program reads a price in dollars and cents,

rounds the price to the nearest dime,

and prints out the revised price.

*/

public class NearestDime

{

public static void main(String[] args)

{

Scanner in = new Scanner(System.in);

double price = in.nextDouble();

int pennies = (int) Math.round(price * 100);

// Determine dollar and cents worth of pennies

int cents;

int dollars;

// Round cents to nearest dime

int dimes;

// Print revised price

double revised = dollars + dimes * 0.1;

System.out.printf("%.2f\n", revised);

}

}

PROBLEM 2 (4.101)

Complete the program named GetVowels below so that it reads in a string, finds all the vowels in that string, and prints out the vowels. For example, given the input string of "Hello, World!", the program should print the string "eoo".

import java.util.Scanner;
/**
Reads a string and prints out all vowels contained in that string.
Vowels are A E I O U a e i o u.
Input: the value of s, a string
Output: a string containing all the vowels in s,
in the order in which they appear in s
*/
public class GetVowels
{
public static void main(String[] args)
{
String r = "";

Scanner in = new Scanner(System.in);
String s = in.nextLine();

System.out.println(r);
}
}

PROBLEM 3 (4.16)

Rewrite the following do loop into a while loop.

int n = in.nextInt();
double x = 0;
double s;
do
{
s = 1.0 / (1 + n * n);
n++;
x = x + s;
}
while (s > 0.01);
