Multiplication Worked But Division Didn't Work

Mar 5, 2014

I was trying to execute the following program and the multiplication worked but the division didn't work.

import java.util.Scanner;
public class BodyMassIndex {
public static void main(String[] args) {
// Prompt the user for weight and height
// Create a scanner
Scanner input = new Scanner (System.in);
System.out.println("Please enter your weight in pounds");
int weight = input.nextInt();
System.out.println("Please enter your height in inches");
int height = input.nextInt ();
double BMI = weight * (0.45359237)/ (height * 0.0254)*(height * 0.0254);
// the weight * (0.45359237) executed but it wasn't divided by (height * 0.0254)*(height * 0.0254)
System.out.println ("Your BMI is "+BMI);

Making Time Calculator Work / Modulo Division Not Working

Oct 22, 2014

Prompt for the project is "Write a program that will ask the user for a number of seconds and output the equivalent period of time in days, hours, minutes, and seconds.The program should:

-Use modulo division to calculate the number of days, hours, and minutes.
-Use compound operators when making assignments.
-Proper formatting and use of comments
-Symbolic constants defined as the number of seconds in a minute, hour, and day.

For example: final int sec_in_min = 60;"

Why To Get NoClassDefFoundError Exception When Didn't Change Anything

Feb 23, 2014

My program was working fine and then without changing anything, it has started throwing me a "Exception in thread "main" java. lang. NoClass Def FoundError: medina/client/ClientGameFrame". I'm dumbfounded as to how this can just suddenly appear after I've been working on this program all week. My research has pointed out that it must be my class paths but as far as I know, the class paths are fine....and why would it suddenly stop working if it was my class paths ?

I have just been trying to compile in netbeans and that's when the error occurs, though I just tried packaging to a jar and the jar works fine...though why not in netbeans?

Here is what im trying to do

Write a class that accepts a user's hourly rate of pay and the number of hours worked. Display the user's gross pay (gross pay = hours worked * hourly rate), the tax withheld (tax withheld = gross pay * tax rate) and the net pay (net pay = gross pay - tax withheld).Use a named constant for storing the tax rate of 0.15

Weed Out All Prime Numbers Without Using Any Kind Of Division?

Dec 15, 2014

The challenge is to weed out all the prime numbers without using any kind of division (%, /). My code doesn't weed out certain numbers, such as many multiples of 5, the number 49, etc, and I am not sure why. Here is my code.

My logic for the for loops was this: Starting with the upper numbers of the ArrayList, find every number that is a multiple of that number and remove it from the ArrayList. Every time you find a multiple, increase the variable multiply, so the program knows what the next multiple to look for.

// program doesn't work yet.
import java.util.ArrayList;
// import java.util.ListIterator;

public class Sieve2
{
public static void main(String[] args)
{
int upperLimit = 55;
ArrayList<Integer> primes = new ArrayList<Integer>();

[Code] .....

And this is the output:

1 2 3 5 7 11 13 17 19 23 25 29 31 35 37 41 43 47 49 53 55

Making Squares Of Numbers Without Multiplication?

Oct 22, 2014

so for my computer science class, we have the following problem:

In your documentation be sure to say which loop you thought was easier to implement for this program and why Write a program that produces the following outputs. The first line of output must be written using a For-Loop. The second, using a While-Loop and the third using a Do-Loop.

You look at the program and smile because you see that the series is just the numbers 1-10 squared...just one line is in reverse order. No problem! As you start typing you discover that the number 8 key on your keyboard is not working. For this program you are unable to use the multiplication key

So, back to the drawing board. By staring at the sequence a light comes on and you are able to quickly finish this program WITHOUT using mulitiplication (or the Math class/ solve with arithmetic operators +, - or / ) .

Sample output:

For Loop
1 4 9 16 25 36 49 64 81 100

While Loop
100 81 64 49 36 25 16 9 4 1

Do While Loop
1 4 9 16 25 36 49 64 81 100

I have the "for" done, but I did it with a "for" in the beginning but then had a multitude of nested "if" loops so that I could do 7*7=7+7+7+7+7+7+7

Rows And Columns In The Form Of Multiplication Table?

Mar 12, 2014

I am making rows and columns in the form of a multiplication table, listed below is my code:

package assignments;
 public class MultTable {
public static void main (String [] args) {
  int row, column, x, y;
  for(row = 0; row < 8; row++)

[Code] .....

If you see my sample run you can see that I have the multiplication table down but, I haven't completed it. I have to make the bottom left half of the whole table blank somehow. For example, I have to make it halfway through the middle of the table the bottom left half full of white space...

5 6 7 8 9
12 14 16 18
21 24 27
32 36
90

hm, it's supposed to be the other way around horizontally.

Java - Integer Limits / Multiplication And Exponents?

Jan 10, 2014

noticed that if I use integers only and simple multiiplication to get my exponent results (in this instance I was looking into Base 26) what is returned is odd, BUT consistent results once I surpass the integer upper limit of 2,147,483,647. I anticipated that once this limit was reached the program would blow up somehow, but no.

public static void main(String[] args) throws IOException{
// TODO Auto-generated method stub
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter an integer exponent: ");
int i = Integer.parseInt(br.readLine());
CountAlpha ca = new CountAlpha();

Multiplication Table - Single Field To Store Integer

Feb 26, 2014

Steps are:

Create a new class, MultiplicationTable, that has a single field to store an integer multiplication table

Create a constructor that takes a parameter for the maximum number to be multiplied in the table. For example, MultiplicationTable(9) would have a maximum value of 81, where as MultiplicationTable(12) would have a maximum value of 144. Initialize the field in the constructor with the appropriate multiplication values.

Create a multiply method that takes two integers as parameters and returns their multiplication value by looking it up in the field. Make sure to test this method with values greater than the max the table should have stored. How can you handle these cases?

Create a main method that repeatedly tests multiply by printing out the entire multiplication table.

So far i got:

Java Code:

package collectionsHw_netid;
class MultiplicationTable {
// field
int mt;
MultiplicationTable(){
{
for (int i=0; i<=9; i++)

[Code] ....

Is my code right? also how do i print it out? the professor told us that everything should be outside of the main method...

Servlets :: Generate M By N Multiplication Table Based On User Input

May 8, 2014

I have a basic html form with one user input text box labeled "Enter a number" and a submit button labeled "Create a multiplication table". This is the working with a servlet to display an html formatted multiplication table. Everything else is working fine just the formatting is off; I can't seem to get the top row and far left column to number properly. It should look like this with the top row of numbers beginning with a blank cell and then numbering 1 thru n (depending on what the user selects. The first column should be the same, a blank cell and then 1 thru n. Then the multiplication table should be in the rows/columns of the table. Picture this:

I can't get mine to start with a blank cell in the top left-hand corner, instead it has 1 in that cell and the table starts calculating with 2x2.

Servlet code:

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

Prompt User For Input Number And Check If It Is Greater Than Zero - Java Multiplication

Apr 13, 2014

Write a program that prompts the user for an input number and checks to see if that input number is greater than zero. If the input number is greater than 0, the program does a multiplication of all the numbers up to the input number starting with the input number. For example if the user inputs the number 9, then the program displays the following sum:

9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 362880

That's the question I'm getting and so far all I've got is

import java.util.Scanner;
public class Lab4Q3
{
public static void main (String[] args)
{
int keyboard;

Getting 64 Bit JVM To Work?

Jun 18, 2014

The problem is as follows: I've been running java script using git bash and at one point it tells me that I need to increase heap size because apparently it takes more than 1gb to run. However although I manually increase it via control panel>programs>java nothing changes. I've been told that I need to ' figure out how to use 64bit java (and a VM that supports 64bit) in order to increase the maximum memory allocation (heap size) to something north of 2g.'

My laptop has 8GB worth of RAM (Windows 7)so it shouldn't technically have problems running anything above 1G. But there is apparently a 1GB wall But increasing the heap size to above 2G results in an error stating that VM doesn't initialize within git bash, I thought that my java is 32 bit so I downloaded a 64 bit java. Now how and if it is even possible to allocate a program to run under 64 bit java and if I should delete the other java version.

How Does Recursion Work

Dec 13, 2014

how does recursion works, I don't understand why it prints al numbers going up again?This is the code

void print2(int n){
if (n<0){
out.printf(" %d",-1);
return;
}
out.printf(" %d", n);
print2(n-1)
out.printf(" %d", n);
}

this should be the output if n is 6: 6 5 4 3 2 1 0 -1 0 1 2 3 4 5 6.

Creating A Chart For Work?

Mar 6, 2015

I need to create a chart for work and comes across this sample from mbostock's chord diagram (bl.ocks.org/mbostock/4062006).

I only need to revise the tick label (names, display positions) but I don't know how to do it as I have 0 experience with Java.

My sample data for the var matrix is

[0,100,100,100]
[0,0,99,98]
[0,0,92,84]
[0,99,0,0]

which shows flows between country A, B, C and D.

I would like to revise the tick labels, so that:

1) Instead of showing 0K 5K 10K, I would like to show the country names (A - D), with no number or tick. I figured out this one by just commenting out all the codes relating to ticks.

2) Place the country names in the center of the arch. I don't know how to do this one.
