I am looking for a good and reliable library to read a string to construct a list of Integers, Doubles, Booleans, etc. This library should be robust enough to handle faulty input from an inexperienced user.
Write a program that reads an integer and displays, using asterisks, a filled diamond of the given side length. For example, if the side length is 4 the program should display.
* *** ***** ******* ***** *** *
I have it where it displays the top half of the diamond. But i cannot figure out how to get it to draw the bottom half.
import java.util.*; public class E616 { public static void main(String[] args) { Scanner input=new Scanner(System.in); System.out.print("Enter number of rows. "); int N=input.nextInt();
Basically i have a question ask me to write a program that read integer from keyboard until a negative number is entered, and then print out the max and min out of the number i have entered.
This is what i have done already which works, but i need to ignore the negative number when print out max and min...which i dont know how to do so. when i compile this program now it will always give me the negative number i enter at the end as minimum. which i need to ignore
Also if negative number is entered at once the program should print a error message say max and min are undefined.
public static void main(String[] args) {
Scanner in = new Scanner(System.in); int large = Integer.MIN_VALUE; int small = Integer.MAX_VALUE; while(true) { System.out.print("Enter a integer: "); int n = in.nextInt();
Write a program that reads from the user an integer and reduce it by multiplying its non-zero digits. The result of the multiplication is a number which is to be reduced as the initial one. This process continues until an integer of one single digit is obtained. For example:
Your program should display the number obtained in every iteration.
Sample run1 Enter an integer: 64734502 After iteration 1: 20160 After iteration 2: 12 After iteration 3: 2
Sample run2 Enter an integer: 97737999 After iteration 1: 6751269 After iteration 2: 22680 After iteration 3: 192 After iteration 4: 18 After iteration 5: 8
I want to run a program to add an element as the third element of stack without changing rankings, I am trying to use two stack and I don't know how to push the top of first stack in the second: push(top(); this line
public void ADD(int element,int i ){ if(isEmpty(true)){ push(element);} else{ makeNull(); while((i<=3) && (isEmpty(false))){ push(top(); }
My project in eclipse..I get the error below when I run MyTagUser.jsp -

I've already tested with disabled="false", too, but only the Session attribute is saved as NULL, though it appears in the form field. The other fields are saved properly.
Here, I have just tried out to take a value from the database and storing it into local variable then I want to have that value in the value attribute of <input> tag but somehow, I can't get it..
Here, below is my code..

We've implemented the Whitelist and there's an application I need to use the Force attribute with, however, I'm unable to get this to work. As I read it, this code says use Java 1.6_24 for Example.com and any other applications are blocked from running. There are three versions of Java installed - 1.6_24, 1.7_65 & 1.8_25. The Java console shows 1.8_25 being called.
Here's the ruleset.
<ruleset version="1.1+"> <rule> <id location=https://example.com /> <action permission="run" version="1.6_24" force="true" /> </rule> <rule> <id /> <action permission="block"> <message> This application is blocked due to Java restrictions, please contact the Service Desk for assistance.</message> </action> </rule></ruleset>
I also tried
<action force="true" permission="run" version="1.6.0_24" /> and also <action force="true" version="1.6.0_24" permission="run" />.
The Java console is still showing version 1.8.0_25.

I can't seem to get the value for integer1 and integer2 to pass with the setValue method. I get a runtime error stating the I need to have an int value for these two integers.
I'm looking to figure out if it's possible to do the following:
HttpSession session = request.getSession(); session.setAttribute('name', 'Jane_Doe'); // more code here session.setAttribute('name', 'John_Doe');
Obviously, you can use the HttpSessionAttributeListener to determine which attribute has changed. However, it doesn't return the new value but rather the old one.
You can use the HttpSessionEvent listener to determine when a session object has been changed.
Is there a way you can determine when a session object changes (and it does NOT occur when the setAttribute method is called...) and determine the updated key:value pair?
i have a field that varies from 10 to 3000 VARCHAR in DB. A field called IDTEXT in a database that can be even a single word or up to a max of 3000. I want to display that in a form. Based on its size i want to very the size of the <h:inputTextarea>. How can i do it..will i be able to set row property from bean?
Being new to java I am a bit lost as to why my session attribute for this banking app wont add the deposits to the session var... it just keeps going back to the amount I set it to originally - so if I set the beginning balance to 3000 then deposit 100 it becomes 3100, but if I then try deposit another amount eg. a extra 200 it becomes 3200 not 3300 like it should be !!
import javax.servlet.*; import javax.servlet.http.*; import java.io.*; import java.util.*; import java.net.*; import java.text.DecimalFormat; public class SessionBank extends HttpServlet

I just want to know how to pass an Attribute along with its value from servlets to a plain Java class. Im using java beans but it's showing null...So as an alternative im using session to access variables in java class..
I am generating java script tag and javascript code in servlet and displaying it in each jsp page. i include this in every jsp in my application. I am preparing the following javascript content and diplayin each jsp
<script type="text/javascript"> BOOM.addVar (clientId = SOME universal unique ID ) </script>
the clientid will be uniqueid it gets generated every time.
Here my question is, is there any possibility the clientId will be store in browser cache or third party cache server. if yes how to prevent clientId from cache.
I don't want to prevent the whole jsp file from cache. i just want to prevent only that particular field. so that i can use advantages cache and also prevent particular header field to be cached.
Also can we prevent particular http header attribute from cache.
I have to fetch only the book name attribute and use it for display .However say for example ,I have got the list of Books ie(C#,Oracle,Archius) ,passing this value to a method should return me an array of URL nodes value within it.
The idea is to display the book names in a list and then on user selection , corresponding URL needs to be fetched.
Was able to get the loop for traversing the nodes
[java=code] NodeList nodeList = document.getDocumentElement().getElementsByTagName ("Book"); for (int i = 0; i < nodeList.getLength(); i++) {... [java=code]
So
a) Display the BookNames
b) Get the corresponding URL's for the particular book if I pass the Bookname
In a form i used <h:commandButton> i called a Javascript function. Though the function returns false , form is submitted and action method is called. I used like this
I'm creating a simple login screen and I need to focus on the first field "login" after I click a submit button, so when the page return. I tryed using JS :
