Numbers Divisible By 6 - Code Is Giving Different Result Then Expected
Aug 22, 2014
I am having problems with writing a simple program to see if a number is divisible by 6.
public void run() {
println("This program will display all numbers divisible by");
println(" 6 between 1 and 100.");
int x =1;
boolean divide =(x%6==0);
[Code] ....
It is telling that every number is not divisable by 6?
Write a program that will read two numbers and an integer code from the keyboard. The value of the integer code should 1, 2, 3, 4. If the value of the code is 1, compute the sum of the two numbers. If the code is 2, compute the difference (first number minus second). If the code is 3, compute the product of the two numbers. If the code is 4, and the second number is zero, compute the quotient (first divided by second). If the code is not equal to 1,2,3,4, display an error message. The program is then to display two numbers, the integer code and the computed result to the screen
here is the code that I have so far:
public static void main(String[] args) { Scanner read = new Scanner (System.in); int num1, num2, code, sum; System.out.println("Please enter a number"); num1 = read.nextInt();
(5,0) with cost 12 (6,0) with cost 14 (6,1) with cost 15 (6,2) with cost 20 (7,2) with cost 44 (7,3) with cost 52 (7,4) with cost 54 (6,3) with cost 71 (5,3) with cost 74 (4,3) with cost 96
Greatest path is of length 10.
Now, the code that I have works, kind of. Instead of recurring several times at each point, it only recurs once.
So say I'm looking at (1,1). With (1,1) being 57. The area around it looks like this.
97 47 56 35 57 41 89 36 98
Now when I look at it, there are several paths it can take. It can go 57, 97 or 57, 89 or 57, 98. However, I'm pretty sure that it just uses the first one that corresponds with the first if statement that is valid. So I start checking north of the value, then northeast, then east, then southeast, which at southeast is where I find my first greater than value. After it finds it's first valid number, it then continues from that number, instead of checking if there are other longer paths stemming from the original value.
In conjunction with that, you can see that the printout just returns all paths from each value. Which isn't what I want. I need a way to store the longest current path, then check each path after to see if it's longer. If it is, it's replaced, if not, it stays the same.

Why this extremely simple program seems to be giving me a negative value for amount of calculations done within one minute ( Just using it as a bit of fun to see how different computers in the office perform).
Java Code:
class Benchmark { public static void main(String[] args) { long endTime = System.currentTimeMillis() + 60000; int count = 0; for (int i = 0; System.currentTimeMillis() < endTime; i++) { double x = Math.sqrt(System.currentTimeMillis()); count = i; } System.out.print(count + " calculations per minute"); } } mh_sh_highlight_all('java');
I am getting results between -2.1billion and -3.4billion which to me would make sense since they are not the best computers in the world but I would be expecting a positive value?
My interest in Java leads me to try and print numbers from 1-100. The output should show all numbers from 1-100 and each number that is divisible by by 13 should be replaced with a string "Fuzzy".
public class Fuzzy { public static void main (String[]args){ for(int i = 0; i < 100; i++) if(i % 13==0) System.out.print(i + "fuzzy"); } }
For some reason, the averages aren't calculating correctly. I'm aware I need to convert to double if I'm dividing by an odd amount but that itself isn't the issue. It's just simple easy divisible numbers that are not being calculated correctly. For instance, (10 + 10 + 10 + 50) / 4 = should be 2 but I get 10.
Here is the code:
import java.util.Scanner; public class Avg { public static void main(String[] args){ Scanner inputGains = new Scanner(System.in); int userInput = inputGains.nextInt();
I want to write a method which would give us a rectangle with numbers. The input is an integer which represents the length of a line in rectangle and the result type is void. The example for n=4 is:
public class ProcessMarks { private static final int NMARKS = 125;
[Code] ...
Result (it's repeat number): *Mode is = 53 *Mode is = 53 *Mode is = 53 *Mode is = 53 *Mode is = 53 *Mode is = 62 *Mode is = 62 *Mode is = 62 *Mode is = 62 *Mode is = 62 *Mode is = 67 *Mode is = 67 *Mode is = 67 *Mode is = 67 *Mode is = 67 *Mode is = 77 *Mode is = 77 *Mode is = 77 *Mode is = 77 *Mode is = 77 *Mode is = 78 *Mode is = 78 *Mode is = 78 *Mode is = 78 *Mode is = 78 *Mode is = 85 *Mode is = 85 *Mode is = 85 *Mode is = 85 *Mode is = 85
Result that i want it to be (number appear only once):
*Mode = 53, 62, 67, 77, 78, 85
or
*Mode is = 53 *Mode is = 62 *Mode is = 67 *Mode is = 77 *Mode is = 78 *Mode is = 85
I'm currently working on a program that is supposed to translate morse code and then display the result and I'm stuck, my program has tons of errors when I try to compile.
public class Assignment10 { public static void main ( String [] args ) { String str = Input.getString("Please type in a word"); char [] letters = {'a','b','c','d','e','f','g',
The code here I have works fine if I just want to ask the user to enter four digits: //java application that asks user to input binary numbers(1 or 0) and convert them to decimal numbers import java.util.Scanner; //program uses class scanner public class binarynumber{
//main method that executes the java application public static void main(String args[]){ //declares variables
int digit; int base=2; int degree; double decimal; int binary_zero=0; int binary_one=1; //create scanner for object input
[code]....
The thing is, I want the java application to input more than four digits for the user and I want it to loop it manytimes f until the user ask it to stop.
for (int i = 0; i < letters.length; i++) { double relativeFreq = (onesAverage()/letters[i]); char a = characters.charAt(i); double j = score[i]; System.out.printf();//ToDo
Above is my current code. Basically- There is a string called characters of length 26 (1 char for each letter in alphabet), a double relativeFrequency value which does a calculation and the end result is a number with lots of decimal numbers. The score array has set double values within the array.
What I want to do is create a print f statement where I print out each of the values I initialized above WITH specific amounts of spaces in between. So it should be in this order:
a (spaces) j (spaces) relativeFreq (newLine).
Between J and relativeFreq there should be 4 spaces, however if the value in relativeFreq is greater than 10 (it won't be greater than 100)- then there should be 3 spaces. Everytime I try to create a printf statement my code ends up crooked for some of the values.
for (int i = 0; i < letters.length; i++) { double relativeFreq = (onesAverage()/letters[i]); char a = characters.charAt(i); double j = score[i]; System.out.printf("%c %.4s %.4s%n",a, j, relativeFreq);
I am new to java and do not understand how to use filters very well. I need to write a code that determines if an integer is not divisible by some value. A filter also contains an upstream filter so that this filter can be part of a chain of filters.
I am trying to code using error handling and I am a bit confused on how to go about doing it correctly. My code converts a string that has all numbers into an integer and the error handling should recognize that if it isn't a proper number and ask the user to try again or enter 'q' to quit.Do I place a throw new exception in the try block and put conditionals like if charAt(i) is some letter or a symbol then throw new exception?
Java Code:
import java.util.Scanner; public class practice { public static void main(String[] args) { Integer finalValue = null; boolean validValue = false; Scanner scan = new Scanner(System.in); int result = 0;
public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.println(" Enter the maximum number "); int maxNumber = scanner.nextInt(); int[]numberList = createList (maxNumber);

I have a problem with the output. It only get as far as marking the multiples of 2. It does not mark the multiples of 3 and so on.Example output: If the range is from 2 to 15 the output is :2, 3, 0, 5, 0, 7, 0, 9, 0, 11, 0, 13, 0, 15 note: 0 means its marked.As you can see it only marks multiples of 2 but it does not mark multiples of 3 above. I think the problem lies in the for loop inside my main method, because the index does not increment.
I am doing a project to generate three names of fruits. When I take out my switch code the numbers generate randomly, but when I added the switch code back I kept getting three instances of "Bars" as if the random numbers all became 5.
public static void main(String[] args) { System.out.println("Enter the amount of money you would like to gamble."); Scanner keyboard = new Scanner(System.in); int num1; int num2; int num3; int money; money = keyboard.nextInt();
the problem which im facing when executing jar file is it is not working same as when i run file using the IDE.When run jar file, it won't open the new frame even the user and pass combination correct.But when i'm compiling using the IDE, it works as charm. The main menu popped up after i logged in.I've tried Clean and Build and it's not working too.
I am having trouble figuring out why java is giving me an error for the symbols. I will post the errors below the code.
Java Code: import java.util.Scanner; public class ShelbyHarms_3_02 { public static void main(String[] args) { Scanner console = new Scanner(System.in);
I have just tried to learn java this week [COLOR="#000000"]and I am being held back by this once installed java jdk I nav to the java file and the bin file and then the javac file to find that the below tab does not exist
A new window should pop up giving the properties of the javac, there should be an attribute called Location..I can see the location option in my documents but in no other folder
I am having issues with the first part of my program. When I got to display what is in the textfile, it only gives me one name two times. I cannot figure out what to do with my outer loop in order for it to read and output the entire data file.
When do you get the error <identifier> expected? I've written a small application where input is accepted by a textfield and based on some condition a dialog should be displayed saying "invalid i/p". But am not able to correct ths particular error ....
