Check Whether Number N1 Is Divided By N2 Without Remainder
Aug 8, 2014Faster algorithm.... I want to know whether a number n1 is divided by n2 without remainder. I know I can simply write if (n1 % n2 == 0) ... But it's not fast enough.
Currently I use:
double div = (double) n1 / (double) n2;
If (div == (int) div){
...
}
This is faster than the mod operator. I just look forward to any micro optimizations or such.
Block Division In Cryptography
Feb 20, 2014I have used FileInputStream class but its not working properly to divide the bits into blocks.I will attach the coding
public static void main(String[] args) {
ReadFileExample newclass = new ReadFileExample();
System.out.println("cryptography");

Java Coding For Block Division
Feb 7, 2014I'm doing project in area of "Cryptography and Network security". I'm having a file with binary Unicode (mean file contain Unicode value of corresponding data (text file)), want to divide that as blocks with the size of 144bits.

Count The Number Of Division That Occur
Feb 4, 2015I am using count++ in my program in order to count the number of division that occurs. It works but outputs:
The number of divisions is 1
The number of divisions is 2
The number of divisions is 3
The number of divisions is 4
The number of divisions is 5
All i want is the last line. How do I solve this?

Weed Out All Prime Numbers Without Using Any Kind Of Division?
Dec 15, 2014The 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
Multiplication Worked But Division Didn't Work
Mar 5, 2014I 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, 2014Prompt 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;"
public class Mod1
{
public static void main (String[] args)
{
int sec, min, hr, day;
final int SEC_IN_MIN = 60;
final int SEC_IN_HR = 60 * 60;
final int SEC_IN_DAY = 60 * 60 * 24;
