Three Ways To Print Dash Character

Feb 14, 2014

Find three ways to make the program below print 20 copies of the dash character '-' by changing /adding just one character.

int i,n=20;
for(i=0;i<n;i--){
System.out.println("-");
}

I found two solutions but till now not able to find the third one. The two solutions are

int i,n=20;
for(i=0;i<n;n--){
System.out.println("-");
}

and,

int i,n=20;
for(i=0;-i<n;i--){
System.out.println("-");
}

How To Print A Character Random Number Of Times

Oct 26, 2011

I'm trying to write a method that will print a string of a random number of X's (from 5 to 20) on a line, then another number of X's on the next line, etc. until the random number = 16.

I have to use while loops and probably fencepost algorithms. I'm confused with how to print the number of x's the random number of times over and over.

Right now, I'm pretty sure my for loop is wrong or unnecessary.

So far, this is my code:

public static void randomX() {
int x = 0;
while (x != 16) {
x = (int)(Math.random()*20) + 5;
for (int i = 0; i <= x; i++);
{
System.out.print("x");
}
}
}

Servlets :: Better Ways Of Securing Webpages Access

Jul 10, 2014

I wish you could share some methods for securing access to webpages of websites you had had a hand on? I know of:

- asking for user credentials from an entry page and processing them inside a javabean to confirm they are equal to those kept in the system before granting further access.
- masking servlets paths in web.xml
- hiding client scripts in libraries that are kept on server

Do you know of other methods?

How To Make Print Employee Button To Print Info Of Other Class

Apr 12, 2014

Basically the class is supposed to have a static variable that keeps track of the number of companies (numberOfCompanies) that have been created and a static method that returns the value of this variable. I need to have a constructor and a method to addEmployee, a method to printCompany, and a toString method. The addEmployee method will check that there is only 1 salesperson, 2 designers, and 4 manufacturing persons at a time and will check that there are no more than 7 employees of the company.

The addEmployee method will return a String indicating what the error is (i.e. "There is already a sales person in this company") or a null if the employee was added. If attempting to name a third company, an error message will be shown. what i have so far but my print company mmethod returns null company class :in which i am obliged to use inputdialog because it says that it cannot return void when i use the showmeassage diaolog.

company class:

import java.util.ArrayList;
import javax.swing.JOptionPane;
public class Company {
private ArrayList<Employees> list ;
private static int numberOfCompanies;

[Code] ....

error message when print button is clicked:

Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: JOptionPane: parentComponent does not have a valid parent
at javax.swing.JOptionPane.createInternalFrame(Unknown Source)
at javax.swing.JOptionPane.showInternalOptionDialog(Unknown Source)
