tgruber5150 / FindTheNumberClosestToZero

Created December 6, 2012 01:30

This program finds the number in an array that's closest to zero.

	import org.junit.Test;

	public class BetterProgrammer05122012Test extends junit.framework.TestCase {
	public static int[] numbers = new int[] {5, 10, -5, 0, 25, 35};
	public static int[] numbers2 = new int[] {5, 10, -5, -2, 0, 25, 35};
	public static int[] noNegativeNumbers = new int[] {5, 10, 15, 25, 35};

	@Test
	public void testBetterProgrammer05122012 () {

tgruber5150 / Total a string of numbers

Created December 5, 2012 02:36

This program pulls numbers out of a string and totals them

	import org.junit.Test;

	public class BetterProgrammingTaskTest extends junit.framework.TestCase {
	public static String numbers = "5 25 35 5" ;

	@Test
	public void testGetSumOfNumbers() throws Exception {
	assertEquals(70, BetterProgrammingTask.getSumOfNumbers(numbers));
	}
	}

tgruber5150 / MultiDimArray.java

Created September 14, 2012 20:17

This exercise demonstrates the nature of 3 dimensional arrays. It might be helpful to think of them as an indexed box, rather than 3 lists.

	import java.util.Random;
	import java.util.Scanner;

	public class MultiDimArray {
	static Random rand = new Random();
	static int count = 0;

	public static void main(String[] args) {

	// 3-D array with fixed length:

tgruber5150 / SalesTax.java

Created September 11, 2012 18:15

Sales Tax Calculator: For either Point-of-Sale or After-the-Sale methods.

	import java.text.DecimalFormat;
	import java.util.Scanner;

	public class SalesTaxInput {

	public static void main(String[] args){
	System.out.print("What are your taxable sales? ");
	double sales = getInput();
	sales = SalesTax.roundTwoDecimals(sales);
	System.out.print("What is your sales tax rate? 1% = .01: ");

tgruber5150 / PickANumber.java

Created September 10, 2012 23:43

Pick a number: You get 5 changes to pick the right number, then you're kicked out of the program!

	import java.util.Scanner;
	public class PickANumber {
	private static int a = (int) (Math.random() * 10 + 1);


	public static void main (String[] args) {
	for (int i = 0; i < 5; ++i) {
	System.out.print("Pick a number from 1 to 10: ");
	Scanner in = new Scanner (System.in);
	int b = Integer.parseInt(in.next());

tgruber5150 / alphabetInNumericOrder.java

Created May 7, 2012 19:43

I refactored the alphabet program so a separate method is easy to copy for other applications. Feel free to use this program, or the separate method; labled 'addOrderAppendage'.

	import java.util.Scanner;

	class Alphabet {
	static String[] fields = {"a", "b", "c", "d", "e", "f", "g", "h", "i", "j",
	"k", "l", "m", "n", "o", "p", "q", "r", "s", "t",
	"u", "v", "w", "x", "y", "z"};
	public static void main(String[] args) {

	String letter = null;
	letter = pickALetter(letter);
