For Loop - Print All Odd Numbers Between FirstNum And SecondNum

Feb 4, 2015

Prompt the user to enter two ints, firstNum and secondNum. Then print all odd numbers between firstNum and secondNum.

Here's my code-- my error is in this line: for(firstNum;firstNum<=secondNum;firstNum++)

The error is "not a statement."

import java.io.*;
import java.util.*;
public class ListOddNumbers
{
public static void main(String[] args) {
Scanner keyboard= new Scanner(System.in);

Unable To Print A Loop Inside Array Of Greater Size Than Loop Itself

Jan 27, 2015

I am trying to print a loop inside an array of a greater size than the loop itself. Like for example I have an array of size 7 but it has only 3 elements.

int[] array=new int[7]
array[0]=2;
array[1]=3;
array[2]=4;

now what I want to do is print these three numbers in a loop so that my array[3]=2;array[4]=3;array[5]=4 ...... till the last one. Also the array could be any size and not just 7.

Aug 22, 2014

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;

Print 2 Lists - 20 Random Numbers And Another List Without Duplicate Numbers

Feb 1, 2015

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];

Print A Diamond Using For-loop?

Mar 26, 2014

I am currently trying to print a Diamond using for-loops but I seem to be confusing my self / over-complicating it.

This is what I have so far [URL]). When I run the code I get [URL].

I want to duplicate it on to the other side but I can't seem to be able to figure out a working for-loop to print it out.

Also, is there a faster/efficient method of doing something like this?

Symbol Won't Print From For Loop

Oct 20, 2014

On line 45 i am trying to add "-" symbol to my output phone number. As of now the out prints like "1800*45*3569377. I want it to print 1800-3569377, or even more ideal: 1-800-356-9377. When printing normally (system.out.println) I can print symbols, but when I try to print from a for-loop it says "unclosed character literal." import java.util.Scanner;

public class Phone_010473030 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter a phone number string: ");
String Phone_num = input.nextLine();
Phone_num = Phone_num.toUpperCase();

Print 10 Numbers Per Line

Feb 6, 2015

Am having trouble understanding how to print my results (I have 50 of them) , only 10 per line.

Im using an array that is 1-50. The first 25 I raise to the power of 2 and print it.

The next 25, I multiple by 3 and print it

Public class KDowling { 
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
double [] alpha = new double[50]; //declare an array 50 indexes
int num=1; // declare variable num
int counter=1;

[Code] .....

I need to get this result:

1 4 9 16 25 36 49 64 81 100
121 144 169 196 225 256 289 324 361 400
441 484 529 576 625 78 81 84 87 90
etc...

Right now they are each printing out on their own line.

Print Out Commas For Numbers

Oct 27, 2014

I've almost got this to work. Right now it prints out one comma for the first set of 3 numbers. For exmaple, if the user input is 12345678 the code will print out 12345,678. I'm trying to figure out how to get it to print out commas for the rest of the numbers. My first thought was to use a loop but I can't get it to work....

private static void printWithCommas(NaturalNumber n, SimpleWriter out) {
assert n != null : "Violation of: n1 is not null";
assert out != null : "Violation of: out is not null";
assert out.isOpen() : "Violation of: out.is_open";
if (n.compareTo(THOUSAND) < 0) {
out.print(n);

Threads - Print Even And Odd Numbers Between 0 And 30

Mar 11, 2015

Here is what I am trying to do:

Write a program to print the even numbers and the odd numbers between 0 and 30 using a single thread and then again using multiple threads.

I already finished the single-threaded program but am having trouble with the multi-threaded one. I have three classes; one class for odd numbers, one for even numbers, and one to execute the code. Here is my code so far:

Even Numbers:

Java Code:

public class EvenNumbers extends Thread {
public void run() {
for (int i=1; i<=30; i++) {
if (i%2 == 0) {
System.out.println("Even number " + i);

[Code] ....

Unfortunately, my output ends up looking a little weird:

Java Code:

Even Numbers:

Print Variable Which Only Exists Within For Loop?

Jul 18, 2014

There's loads of problems with this. What I'm trying to do.

1) get a program to add the contents of an array together, preferably with a for loop and not the heavy handed version I've tried to use here.

2) get the for loop's output just once, since it won't compile or recognise the variable outside of the loop. How do I make the loop's 'counter' variable available everywhere?

public class retint {
 public static void main(String[] args){
int[] onetoTen = {1,2,3,4,5,6,7,8,9,10};
for (int i=0; i<10; i++) {
int counter = (onetoTen[0] + onetoTen[1] + onetoTen[2] + onetoTen[3] + onetoTen[4] + onetoTen[5] +
onetoTen[6] + onetoTen[7] + onetoTen[8] + onetoTen[9]);
 System.out.println(counter); 
}
}

Terrible code, I know. There has to be a more efficient way.

Print Triangle - Loop Is Not Working

Jul 7, 2014

I am trying to make a program that prints triangle... and I did various test on each method to realise that the problem lies with this segment.When I call this method, nothing prints out, I figure there is something with the loop that I am not realizing.the loop is backwards because it's supposed to have the right side edge parralel (when I try to print it out the spaces do not appear, imagine the x are space...), so as each line is looped the # of spaces diminishes

xxxx*
xxx*x*
xx*xx*
x*xxx*
*****

public class test {
public static void main(String[] args){  
for (int countdown = 5; countdown <= 1; countdown = countdown--){
showNTimes(countdown, ' ');
showNTimes(5- countdown, '*');
System.out.println("");
}
}
public static void showNTimes ( int nbTimes, char carac ) {
for ( int i = 1 ; i <= nbTimes ; i = i + 1 ) {
System.out.print( carac );
}
}

int d1 = (this.dollars * 100) + this.cents;
int d2 = (o.dollars * 100) + o.cents;
return d1 - d2;
}

On my main method I have

public static void main(String[] args){
Money money1 = new Money(10, 49);

How To Hold And Print Distinct Numbers

Sep 29, 2014

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

Nested For Loop - Print Out Table Of Angles (sin / Cos And Tan)

Oct 1, 2014

I am working on my java program it prints out a table of angles and the sin, cos, and tan. For extra credit he wanted us to use nest loops to create a space after every five lines. I have come real close to getting this to work but have a problem with the very end of the table. The table needs to stop at 180...

public static void printTable(double angle,double sin,double cos,double tan) { // Method to create a table for the values
for (double j = 0; j <= 180;) {
for (double i = 1; i <= 5; i++) {//loop to print five lines of code
angle = Math.toRadians(j);

[Code] .....

Here is the end of the output of the table:

175.00.0872-0.9962-0.0875
176.00.0698-0.9976-0.0699
177.00.0523-0.9986-0.0524
178.00.0349-0.9994-0.0349
