JSP :: Enter Language And Return Greeting
Apr 4, 2015
I have a class called "HelloController" and it extends SimpleFormController. I have the following method inside of HelloController.java:
protected Map referenceData(HttpServletRequest request) throws Exception {
Map<String,String> language = new dHashMap<String,String>();
language.put("Spanish", "Buenos Dias");
language.put("French", "Bonjour");
return language;
}
How would I create a JSP file that would accept a language as its input and return a greeting in that language? For example, if the user enters "Spanish", then the user should see "Buenos Dias." If the user enters "French", then the user should a see "Bonjour".

So I am currently writing my first assignment and have run into problems with my coding. The task was to have someone enter a 5 digit number and in return, I list each number on their respective lines. We also must create an error if a number other than 5 digits was entered. My problem is that when they enter a 1 or 2,3,4,6,7,8 digit number.. the error message occurs along with the rest of the messages (listing the numbers, etc). I want the program to end (or even re-ask to enter the numbers) if they incorrectly enter the data.

I want to use a method, which takes for example an int and also returns an integer. For example, if the the given integer is strong return a, if it is notstrong return b. How would you write that in a Code?
I want to use that in a more general way. I want to give a method mlong the value X of the type date and let it return an int. Type date consists of 3 int, one of them is the int month.
mlong should return an int depending on the X.moth. at the moment my code looks like this:
// File1:
public class date {
public int day;
public int month;
public int year;
}
// File 2:
public class monthlength {
public int mlong(date X) {
int t;
t = X.month;
if (t == 1 || t == 3 || t == 5 || t == 7 || t == 8 || t == 10 || t == 12)
{ return 31; }
if(t == 4 || t == 6 || t == 9 || t == 11)
{return 30;}
}
}

How to improve my code. I finally was able to create a program that gives you the corresponding letter grade, when you enter in a numeric grade without using an array. The only issue left is that I have to be able to enter 5 grades at a time, and it give me the letter grade for all 5. I have the programming working, but only am able to enter 1 at a time. I am not sure what kind of loop or if I am supposed to use a loop.
public static void main(String[] args){
{
int grade = 0;
Scanner input = new Scanner(System.in);
System.out.println("Enter : ");
grade = input.nextInt();
if (grade >= 90)

Which of these is not a real differentiator for programming languages:
a) Object-oriented / Process-Oriented
b) Interactive / Automated
c) Interpreted / Compiled
d) Strongly-Typed / Weakly-Typed
e) All of the above
f) B and C
g) B and D
Almost all support OOP, Interactive/Automated, Interpreted/Compiled but not sure about Strongly typed/Weakly typed.

In my Icefaces 3 application I have a ManagedBean ancestor that defines common attributes to those they spread it. Including CSS styles to be apply at the menu as icons depending on whether they are selected or not. Classes that extend the CommonMBean class define styles. My question is what do I have to put in the language experssion styleClass to tell him that the getter to use is that of the parent class.
CommonMBean.java
package com.omb.view;
public class CommonMBean
private String menu1Css = "";
private String menu2Css = "";

In the servlet class I have:
String name = "James Bond";
Session.setAttribute("name", name);
Why is the attribute name and attribute value the same in all the books I've read. I know one is a string literal and one is an object but must it be the same?
Second thing I'm confused about... let's say I change the servlet code to
String name = "James Bond";
Session.setAttribute("hisname", name);
When I try to access it using JSP:
${sessionScope.name}
it works fine. So what is the point of the first argument in Session.setAttribute() ?

How do i take input values for TwoDPoint (which are objects) and return it back in numerical values also print them.
When i create an object in main method and pass values to my function of return type TwoDPoint,it gives error:- found int,int need TwoDPoiint,TwoDPoint.
// Here is what i tried to do:
Created class TwoDPoint that contains two fields x, y which are of type int. Defined another class TestTwoDPoint, where a main method is defined.In the main method created two TwoDPoint objects.
Then I modified the class TestTwoDPoint and add another function to it. This function takes two TwoDPoints as input and returns the TwoDPoint that is farthest from the point (0,0).
Then I added another function to TestTwoDPoint. This function takes two TwoDPoints as input and returns a new TwoDPoint whose x value is the sum of x values of the input TwoDPoint's and whose y value is the sum of the y values of the input TwoDPoint's.
class TwoDPoint {
int x = 2;
int y = 4;
}
class TestTwoDPoint {
public static void main(String args[]) {
TwoDPoint obj1 = new TwoDPoint();
System.out.println(obj1.x);
System.out.println(obj1.y);

Looking for some simple use cases for servlet filters other than tracking requests ? I was thinking of using a filter to filter out offensive language from entered text. Would that be a good use case ?

My program is supposed to let me enter the following info for 3 employees: name, number of hours worked this week, and hourly pay rate. It lets me enter the name for the first employee, but for the second and third, it skips over the name and forces me to enter the number of hours worked and pay rate without a name. I have the code and the output posted below. First the program code:
Java Code:
import java.util.Scanner;
public class SalaryCalc {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String name;
double hours;
double rate;
double grossPay = 0;
double overtime;
[code]...
Enter hours worked this week: mh_sh_highlight_all('java'); Notice I can only enter the name for the first employee (Bigfoot). If I wanted to enter "Nessie" for my second employee's name, it skips over the name prompt and prompts me for the hours worked instead.

I'm currently taking a Java Programming module in college, the program we are using is jGrasp and I'm currently stuck on one aspect of the language.
I did VB last year and I enjoyed it and got good grades so I'm comfortable with Java in terms of compiling the code correctly and getting it to run with no errors.
But for a project we got yesterday, the user must be able to enter data (e.g. an answer) into jGrasp without using a GUI. This is the case because we won't be dealing with GUIs until next semester.
I'm able to handle the rest of the project, but the part which I can't figure out is how the user can interact with jGrasp without the aid of a GUI.

I'm working with a project there ill need to enter some values for an Object and for this i'm using JTextField. However some of the variables are of the types double, int and bool. Is there a different method of reading thees types?
for example:
double playTime = this.playTime.getText();
This won't work because playTime is of type double and .getText(); takes a String.
How will i handle this? Id rather not convert from String to Double if its possible.

I am suppose to design a problem the prompts the user to enter a String. Based on the input from the user, have the program prompt with a full description of the playing card entered. Below is a table of the notation and meaning:
Notation Meaning
A Ace
2...10 Card Values
J Jack
Q Queen
K King
D Diamonds
H Hearts
S Spades
C Clubs
Use the .charAt(...) to extract each character from the user's input and build a switch statement to determine the full description.
import java.util.Scanner;
public class PlayingCardIdentifier {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter a card notation: ");
String s = input.nextLine();

I am learning Java on my own, and I am creating little programs to do so.The program below asks the user to input text and hit enter. When user does that, it asks if that is correct. If the user enters "y," the program ends. That's good.If the users enters "n," the strGrategul is set to empty which triggers the while statement to start over again. That's good. However, when the program asks the user to "Tell me one thing you are grateful for..." it doesn't wait for user input. Instead it skips to "You said ''? Enter 'y' or 'n'" It thinks the user enter an empty line.
public static void main(String[] args) {
String strGrateful = "";
String strGoal = "";
String strContinue = "";
Scanner scn = new Scanner(System.in);
[code]....
