User To Input Integer And Then Outputs Both Individual Digits Of Number And Sum Of Digits
Feb 2, 2015Goal is to: Write a program that prompts the user to input an integer and then outputs both the individual digits of the number and the sum of the digits.
First I don't know where I made mistakes here, and the only error it finds right now is that str2 was not initialized and I cannot figure out where/when to initialize it.

Array Sorting - Ascending And Descending Order
Apr 10, 2014I am sorting an array in ascending and descending order. I am using the nethods in Arrays as below
Arrays.sort(myArray)
I want to print both input and output array in sysout.
Object[] ipArray = [45,8,32,41,11,7];
Object[] opArray;
Object mArray = ipArray;
Arrays.sort(mArray); This is changing the ipArray too ?
How can I get my input array unmodified ?

Sorting User Input Arrays Into Ascending Order
Oct 15, 2014I am writing a program that grab user input number which represent beats per minute separated by commas. It then parses the numbers and reorders them from smallest to largest and then outputs the average, medium, maximum and minimum number all in separate lines. I am having trouble getting the array to sort the input from smallest to largest. It is currently only working for 3 numbers inputted. Anything more will not reorder it.

Copying All Elements In Array A To B Sorted In Ascending Order
Apr 7, 2014How do u copy all the elements in an array eg A into another array eg B? This is the question:
An array A contains integers that first increase in value and then decrease in value,
For example, 17 24 31 39 44 49 36 29 20 18 13
It is unknown at which point the numbers start to decrease. Write efficient code to code to copy the numbers in A to another array B so that B is sorted in ascending order. Your code must take advantage of the way the numbers are arranged in A.
This is my program:
This is the error message:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException

Array Sorting In Ascending Order - Displaying Integers
Oct 21, 2014I couldn't where the problem with this code. The question is : (Write a program that reads in nine integers and sorts the value in the ascending order. Next, the program restores the sorted integers in a 3 x 3 two-dimensional array and display the integers as shown in the result.) And this how i did it:
package test1;
import java.io.*;
import java.util.*;
public class test1{
public static void main(String[] args){
int[] hold = new int [9];
Scanner sc = new Scanner(System.in);
System.out.print("Enter 9 integers, press <Enter> after each");
{
for (int i = 0; i < hold.length; i++);

Consider Sequence Of Digits From 1 Through N In Increasing Order
Sep 3, 2014Consider the sequence of digits from 1 through N (N<=9) in increasing order: 1 2 3 4 N
Insert either a +(for addition) or a - (for subtraction) between each of the digits so that the resultant sum is zero. Print all possible combinations that sum to zero.
Example: Enter a number: 7
1+2-3+4-5-6+7=0
1+2-3-4+5+6-7=0
1-2+3+4-5+6-7=0
1-2-3-4-5+6+7=0
Extract Higher-order Bits Of Random Number In Order To Get Longer Period
Mar 1, 2014One of the random number generators in Java extract the higher-order bits of the random number in order to get a longer period.
I'm not sure if I understand how this is done. Suppose that the random number r = 0000 1100 1000 1101. If we extract the 16 most significant bits from r; is the new number r = 0000 1100 or r = 0000 1100 0000 0000?
Occurrence Of Digits In A Number
Aug 29, 2014Make a program which takes input from the user (6-digit number) and check how many times each digit gets repeated in the number. Java GUI was used (Netbeans 6.5.1).This is my code. I took the input via a JTextField named tf and displayed the output on JTextArea ta.
- arrays not used as we haven't studied them yet
int num= Integer.parseInt(tf.getText());
int no=num;
if(num<100000)
ta.setText("Invalid Input. Please Enter 6 digit number");
int n1= num%10;
num=num/10; //stores last digit
[code]....
How do I omit the last 5 lines? This problem occurs whenever I input a digit with any recurring digit.What changes/additions should I make?
Calculate SUM And AVERAGE Of ODD Number Digits Between 25 And 75
Jun 19, 2014You are to write a parallel program that will receive a large array of unsorted integers containing digits from 0 to 99. The program will have to calculate the SUM and AVERAGE of ODD number digits between 25 and 75 (inclusive).
The user may specify the size or the array and the total processor that the machine has. The size of the array must be divisible by number of processor. Based on the given size, the computer will generate random integer numbers automatically to populate the array.
The program should display the status of the calculation for each processor. The result should be displayed after all calculations are completed.Error messages should be displayed appropriately
a) Write a sequential (non-parallel) program that will accomplish above task.
b) Write a concurrent (parallel) program that will produce the result of the above task.
Count Number Of Digits After Decimal Point?
Jul 21, 2014Given a Numbers instance, whose fields are arrays of all the built-in Java numeric types (int, long, float, double, big-decimal, etc), write a method to sort all the numbers into a master list, and then print out the numbers where the number of digits past the decimal point is equal to the index of the number in the master list.
Is there a function in Java that will give me just the numbers after the decimal? I tried Decimalformat but couldn't get it to work. Here is what I have so far; however, I think I might be on the wrong track.
public class Numbers
{
public static void main(String[] args) {
Byte bNum = new Byte((byte) -50);
Integer iNum = new Integer(168);
Long lNum = new Long(100000L);
Short sNum = new Short((short) 10000);
Float fNum = new Float(12.19f);

Formatting Double To Fixed Number Of Fractional Digits
Apr 6, 2014Where do I find a subroutine similar to this:

For years I have been using output subroutines I wrote long ago.
Now I need this kind and can't remember where it is.
How do I print doubles to a fixed number of digits to right of the point?

Take User Input And Display Sum Of Digits Of Entered Number
Nov 6, 2014I have returned with yet another problem but I think this one might be a bit easier to fix.
So the whole MO of this program is to take user input, and display the sum of the digits of the number they entered. I am supposed to do this by utilizing methods. So far this is what I have and when I compile it tells me that it "cannot find symbol", which I don't understand as I define what "m" is in the for loop. The other error is that it says:
"Exercise6_2.java:22: error: incompatible types: possible lossy conversion from long to int
return result;
^
I don't understand why it's giving me this error nor do I understand why result seems to inherently be an int. (Also the public static int sumDigits(long n) method was given to me by the book so that is what I am supposed to use).
import java.util.Scanner;
public class Exercise6_2 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter a integer");
long n = input.nextLong();

Prompt User To Input Integer And Then Output Both Digits Of Number And Their Sum
Jun 7, 2015Write a program that prompts the user to input an integer and then outputs both the individual digits of the number and the sum of the digits.
Now I have a code for spacing out the integers, and I have a separate code for adding the digits. But I am not sure how to merge them together. Both of them work independently
Spacing code:
import java.util.*;
public class SumoftheIntegers
{
static Scanner console=new Scanner(System.in);
public static void main(String []args) {
int num1, test, rem;
int counter = 0;
[Code]...
Now the sum of the integers code:
import java.util.Scanner;
public class sum
{
public static void main(String[] args)
{
// Create a Scanner
Scanner input = new Scanner(System.in);
// Enter amount
System.out.print("Enter an integer: ");
int integer = input.nextInt();

Mar 3, 2015I am having trouble putting an int value into an array. The error code I get at compile time is this: "error: array required, but int found". The following is snippets of my array initialization and the line producing the error.

Draw Ascending Stairs Using For Loops
Sep 27, 2014I'm not looking for answers, well I am.. but not just straight given to me. I'm trying to learn but for this program I'm not even sure where to start. One step looks like this:
O *******
/| * *
/ * *
************
It must increase by a constant named STEPS. They ascend from left and go up right.
I'm just gonna start asking some questions I guess. Before I do anything I wanted to know whether I should have the stick man on the step drawn out with print and println statements or try to have him drawn with a loop as well? I'm not sure if my teacher wants everything drawn by characters with loops for each character, or if I can do print statements and draw the stick figure plus some stars and have a loop for multiple characters at once.
Store Data By Their Ascending IDs Using Java
