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.

The question is Write a program that displays all the numbers from 100 to 1000, ten per line, that are divisible by 5 and 6. and separated by exactly a space.
My assignment requirements are to display this in Dialog Box / message box . I have written this code so far
import javax.swing.JOptionPane;
public class Exercise04_10 {
public static void main(String[] args) {
int count = 1;
for (int i = 100; i <= 1000; i++)
if (i % 5 == 0 && i % 6 == 0)
How to display the output in dialog box?

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'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];
[Code] ....

How can I make this program print so the output looks like this ( ignore the - -- lines ):
--------1
-------21
-----321
---4321
-54321
Instead of:
1
21
321
4321
54321
Java Code:
public class c5e18c {
public static void main(String[]args){
int i;
int j;
for(i = 1; i<=6; i++){
for (j = i; j>=1 ;j--){
System.out.printf(j + " ");
}
System.out.println();
}
} mh_sh_highlight_all('java');

I'm going to be taking an object oriented paradigm using java during intersession in a few months. I'm trying to brush up on it a bit. The problem is. Write an application that displays the numbers 1 to 4 on the same line, with each pair of adjacent numbers separated by one space. Write the program using the following techniques:Use one system.out.printLn statement.Use four system.out.print statement.Use one system.out.printf statement.
This is what i have so far .
Java Code: public class Display
{
public static void main(String [] args) {
System.out.print("1 ");
System.out.print("2 ");
System.out.print("3 ");
System.out.print("4 ");
System.out.println(" ");<----is that what that is supposed to look like, and where it goes?
System.out.printf(" %s %s %s %s ");????
}
} mh_sh_highlight_all('java');
i cant test this my console isn't working right, and i haven't finished my compiler install.

write the logic in the below given Java method.
Public static boolean updateNetMap(String filepath, String nodename){
// check the file pointed by filepath to have entry for nodename.
// if it is there, get the start line no and end line no
// Based on the line nos, need logic to remove the contents from the file.
}
Below is the sample node entry, which we need to identify and delete (here nodename is WAS_CD1):
WAS_CD1:
:conn.retry.stwait=00.00.00:
:conn.retry.stattempts=6:
:conn.retry.ltwait=00.00.00:
:conn.retry.ltattempts=6:
:tcp.max.time.to.wait=0:

I have a large text file of 1 GB size. I need to print the line when a matching word is found in a particular line. Below is the code I am using. But if there are many lines that has the matching word, it's taking lot of time. Any solution to print the lines much faster.
Scanner scanner = new Scanner(file);
while (scanner.hasNextLine()) {
String line = scanner.nextLine();
if(line.contains("xyz")) {
System.out.println(line);
}

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);

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:

Handling, AssertionsProgram - Thread>java MultiThread
Even Numbers:
Odd Numbers:
Even number 2

I am trying to cast an integer into a double. it works but I need two decimal number after the dot and for example I can print 7.51 but how can I get it to print 7.50 and not 7.5
public int compareTo(Money o){
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);
Money money2 = new Money(2, 99);
System.out.println("result: " + "$" + (double)money1.compareTo(money2)/100);
}
It prints 7.5 but I want it to print 7.50, how do I do this .....

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

2.Check the Vehicle...Assume that vehicles are going through a two-way traffic intersection. There are three types of vehicles: car, motor bikes and trucks. Generate a series of 10 random integers, between 1 and 3, inclusive. The numbers represent the type of vehicle as stated below:
NumberVehicle Category
1 Car
2 Motor bikes
3 Trucks
Write a program, using a for loop, to count how many vehicles going through the traffic intersection are cars, motor bikes and trucks. Then, the program should print out the numbers for each vehicle category. There is no user input for this program.
