User To Enter 10 Numbers And At The End Prints Out Distinct And Non-repeated Numbers
Nov 23, 2014
I have to make a program that prompts the user to enter 10 numbers and at the end it prints out the distinct numbers and then the other numbers that weren't repeated...
I have the part where it prints out the distinct numbers but I stuck on how to make it print out the other numbers that didn't repeat...
import javax.swing.JOptionPane;
public class DistinctNumbers {
public static void main(String[] args) {
String getInput;
int input;
int[] numbers = new int[10];
[Code] ....

so for class I have an assignment that involves printing distinct numbers. the assignment is as follows: Write a program that reads in ten numbers and displays the number of distinct numbers and the distinct numbers separated by exactly on space. Here is what the input and the output are supposed to look like:
Input: Enter Ten Numbers: 1 2 3 2 1 6 3 4 5 2
Output: The Number of distinct numbers is 6
The distinct numbers are: 1 2 3 6 4 5
So far I have the entire code but right now it only prints out the distinct numbers, not how many distinct numbers there are. what that part of the code would look like?Here is my current code:
public class exer75 {
public static void main(String[] args) {
java.util.Scanner input = new java.util.Scanner(System.in); //create scanner system
System.out.println("");
System.out.print("Enter Ten Numbers: "); //prompt the user to enter 10 numbers
int[] values = new int[10]; //create an array to hold the numbers
[code]...

This application is supposed to allow a user to enter the names an phone numbers of up to 20 friends, until the user enters "zzz" or 20 names. Then the console is supposed to display the names and have the user enter a name to get the phone number. Here's my code:
import java.util.Scanner;
public class PhoneBook{
public static void main(String[] args){
String name;
int phoneNumber;
final int nameAmount=20;
[Code] ....
I can't seem to get it correct, every time I correct a compiler error, another set of them appear.

I am able to get the integer in the array printed but I am lost on how to hold and print the distinct numbers.
This program will read in 10 numbers from the user via the console. It will display on the console only the distinct numbers, i.e. if a number appears multiple times in the input it is displayed only once.
Here is a sample test run:
Enter an integer: 2
Enter an integer: 6
Enter an integer: 1
Enter an integer: 8
Enter an integer: 6
Enter an integer: 1
Enter an integer: 2
Enter an integer: 4
Enter an integer: 7
Enter an integer: 5
The number of distinct values is 7
2 6 1 8 4 7 5

I got this code with mode methods. The results is not exactly what I want.
Code:
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.Random;
import java.util.*;
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

Write a program (TwoIntegers.java) that prompts the user to enter two positive integers and prints their sum (by addition), product (by multiplication), difference (by subtraction), quotient (by division), and remainder (by modulation). When the user enters 5 and 3, the output from your program should look exactly like the following:
Enter two positive integers: 5 3
The sum is 8.
The product is 15.
The difference is 2.
The quotient is 1.
The remainder is 2.
import java.util.Scanner;
public class TwoIntegers {
public static void main(String[] args) {
System.out.println("Enter two positive integers: ");
Scanner userInput = new Scanner("System.in");
int integer1 = userInput.nextInt();
int integer2 = userInput.nextInt();

I'm trying to create a circular array which prints out 8 numbers that increase by one and don't exceed 9. If they do, the remaining numbers are printed from 0 on-wards. I have code below which does this job, but it doesn't really use an array to loop back.
Java Code:
package Practice;
public class Practice
{
public static void main(String[] test)
{
number(7);
number(9);

So I'm trying to write a program that prints out the "most-repeated integer" in an Array.
For example: if an array contains {1,2,2,3} It would print out 2 as the result.This is what I got so far and according to my knowledge I think I'm correct but for some reason it doesn't work.. Please give me some inputs.
public class MostInt{
public MostInt (){
int[] array = {0};
for(int i = 0;i>array.length;i++){
if(i==i++){
System.out.println(i);
[Code]...

double CashInsert = Double.parseDouble(CashAmounttxt.getText());
System.out.println("Cash Received: " + "£" + CashInsert);
if (CashInsert<=0 &&(CashInsert <TotalPrice)){
ChangeLeft = CashInsert - TotalPrice;
System.out.println("Total: £" + TotalPrice);
System.out.println("Change Due: " + "£" + ChangeLeft);}
else {
System.out.println("Insuffient funds, please enter £"+ TotalPrice +" or More");}
}
#################################################
Cash Received: £-1.0
Total: £4.85
Change Due: £-5.85
It allows me to enter -1 I've already coded it so the person cannot enter less but -1 works.

I am trying to write a code that allows you to input 2 lists and it tells you if they are identical or not. However, when I enter my fist list I can only enter two values and then it asks for the next list. How would I fix this to allow me to enter more than two values?
Also, If the second list is different it has me enter more values that list one.
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
// Enter values for list1
System.out.print("Enter list1: ");
int size1 = input.nextInt();
int[] list1 = new int[size1];
for (int i = 0; i < list1.length; i++)
list1[i] = input.nextInt();
// Enter values for list2
System.out.print("Enter list 2: ");
[code]...
My output looks like this:
Enter list1: 1
2
Enter list 2: 2
3
2
Two lists are not identical

I tried to create file and write the output of my program in it in java when i use WriteLong then the file does not contain long value, how I create this file my program is to print prime numbers between 500000 to 10000000
public class primenumber {
public static void main(String[] args) {
long start = 5000000;
long end = 10000000;
System.out.println("List of prime numbers between " + start + " and " + end);
for (long i = start; i <= end; i++) {
if (isPrime(i)) {
System.out.println(i);

I've just written a program that generates 100 numbers that range from 0 ~ 25 using arrays, the program calls another method that sorts the even numbers into a separate array and returns the array. I need it to display both arrays, however, when I run my program, the numbers of both arrays are mixed together, and I'm not sure how to separate them.
[ public class Array1
{
public static void main(String[] args)
{
int array [ ] = new int[100];
for (int i = 0; i < array.length; i++)
{
array[i] = (int) (Math.random() * 26);

I'm trying to make a program that generates 20 random integers between 1 and 20 and then prints the list of random numbers to the screen. After that, I want to print a different list to screen with the same numbers from the first list only skipping any number that has been already printed to the screen. So two lists are printed to the screen. The first one has 20 random numbers. The second one has those same 20 numbers but only prints the numbers in the first list that aren't duplicated. So if m
y list of 20 random integers contains three 2s and two 14s, only one 14 and one 2 is printed to the second list. Currently, my code generates 20 numbers from 1 to 20 and stores those numbers in an array but I don't know how to print solve the second part of my problem. I don't know how to print the s different list only without duplicate numbers. As a result, my output is nothing because it doesn't print any number from the first list as oppose to skipping only duplicate one.
public void randomNum(){
System.out.println("Twenty random integers: ");
int max = 20; // max value for range
int min = 1; // min value for range
Random rand = new Random();
int[] all = new int[20];

Create an integer array with 10 numbers, initialize the array to make sure there are both positive and negative integers. Write a program to generate two arrays out of the original array, one array with all positive numbers and another one with all negative numbers. Print out the number of elements and the detailed elements in each array.
public class problem3 {
public static void main(String[]args){
int[] numbers = {1, 2, 3, 4, 5, -1, -2, -3, -4, -5};
for (int i = 0; i<numbers.length;){
if(i>0){
System.out.println(numbers);
}
else
System.out.println(numbers);
}
}
}

I just learned about 2D arrays and am still trying to get a grasp on the concepts. I'm a little confused by how you return all the values in a row to add up and display the sum if the row is entered by the user.
import java.util.*;
public class RowSum {
public static void main(String[] args) {
Scanner s = new Scanner (System.in);
int userpick = 0;
int sum = 0;

I need to fix a program in which the user must get a three random numbers in a row. They have five chances. This is what i have so far:
public static void main(String[] args)throws IOException {
// TODO code application logic here
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
int num1=(int)(Math.random()*(9-0));
int num2=(int)(Math.random()*(9-0));
int num3=(int)(Math.random()*(9-0));

I am writing a program to reverse a user inputted number (Example - 54321 is 12345) The code works great minus the fact that if I input a number that begins with zero, the output will drop the zero. Would it make more sense to just set this up using strings?
import java.util.*;
public class Week7_Programming_Problem
{
static Scanner console = new Scanner(System.in);
public static void main(String[] args)
{
int inputNum, outputNum;

I tried out doing number (generated randomly) != (another number) but that does not work. If I for example want a number between 1 and 10, but I do not want the number 5, what can I do in order to make this happen?

Write a program to maintain a list of the high scores obtained in a game. The program should first ask the user how many scores they want to maintain and then repeatedly accept new scores from the user and should add the score to the list of high scores (in the appropriate position) if it is higher than any of the existing high scores. You must include the following functions:
-initialiseHighScores () which sets all high scores to zero.
-printHighScores() which prints the high scores in the format: “The high scores are 345, 300, 234”, for all exisiting high scores in the list (remember that sometimes it won’t be full).
-higherThan() which takes the high scores and a new score and returns whether the passed score is higher than any of those in the high score list.
-insertScore() which takes the current high score list and a new score and updates it by inserting the new score at the appropriate position in the list

I have a GUI with a textArea for the user to input numbers, a button which should "listen" for those numbers, and then a textField to display the sum. I have my code working for user input of one number; but I'm at a loss as to what sort of loop I need to create to get it to read each line of input. I wasn't sure whether to put this in the beginner forum or here, because I am definitely a beginner.
So my code thus far that works with one input:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JOptionPane;
import javax.swing.JTextArea;
import javax.swing.JTextField;

public class CountStringNumbers { // show the number of Strings that were numbers . . ..
public static void main(String []args){
int count = 0;
int countNumbers=0;
Scanner input=new Scanner(System.in);
[code]...
can count the numbers from 0-9 if the user puted but if it is 10 it doesnt count it , and i need to write all the numbers to have that option. . . . Is there an easy way that includes all the numbers? like if(word.equals(number)){<<<???? (numbers) i know htat doesnt work but is there anything similar ?? ??
countNumbers++;
}
System.out.println("Type Something , , , and to end the the termination type STOP");
word=input.nextLine();
count++;
}
System.out.println("You wrote "+count+" lines wich from those lines "+countNumbers+" were numbers and the programe terminated ");

I need to receive input from the user, as many times as he wants. tha is done with the while loop. I also need to output the min and the max numbers the user enters, therefore i have the if statememnts. also if the user enters only one value i need to output that one value as the min and the max.
int min =0;
int max = 0;
int option = JOptionPane.YES_OPTION;
while ( option == JOptionPane.YES_OPTION){
String dataString = JOptionPane.showInputDialog("Enter an integer");

I'm supposed to use a for loop that runs until it reaches the number input by the user, but I'm not sure how to tell the program to add the user's number along with all of the even numbers in between the user input and 2.
