Retrieving User Input String From Keyboard - Program Errors (try / Catch)

Sep 23, 2014

I need to design, implement, and test a program to input and analyze a name. The program begins by retrieving a user input string from the keyboard. This string is intended to be the user's name. These are the errors we have to search analyze the user input for: No blanks between names firstName and lastName, Non-alphabetic characters in names, Less than two characters in first name, and Less than two characters in last name. Each of these errors must be thrown. All exceptions must be derived from a programmer-defined class called NameException. Each exception should use a detailed message to differentiate among the file types of errors.

This is the format of my NameException class, is the format itself correct? I will fill in the details of each exception I am just wondering if that is how I should set it up.

public class NameException extends Exception {
private String firstName, lastName;
public NoBlanksException(String firstName,String lastName) {
}
public NonAlphabeticalCharactersException(String firstName, String lastName) {

[Code] .....

I was told not to try and catch thrown errors in the main method, would I just create another method in the Driver class to take care of that then?

Singleton For DirContext For LDAP Configuration

Aug 9, 2013

I want to create a singleton for DirContext for LDAP configuration, hence i have used the initialize on demandclass holder idiom as shown below

public class SlmApplicationContext {
/**    
* inner class to hold the instance.    
*/   
private static class Holder {       
private static DirContext instance = new InitialDirContext();   
}
   
/**    
* Method to get the singleton instance of this class.    
* @return SlmApplicationContext    
*/   
public static SlmApplicationContext getInstance() {       
return Holder.instance;    }       
...       
}

Now the problem is if i close the DirContext.close(), when the next request comes the singleton wont    work as the dir context is already closed, hence it will create a new dir context for each requests. Which breaks the singleton concept, hence how we can ensure the  singleton works fine even with DirContext.close()?

Exam Results - Code Should Split Results In Stars In 4 Categories

Nov 30, 2014

I'm doing a program where a user enters in exam results for students. Once he's entered the code, the code should split the results in stars in 4 categories.

I am working with a while loop that prints out infinite results. What I want to do is, if the user enters 2 digits, say "12", it should output 1 "*".

If the user enters "21" and "22", it should output "**".

There are 4 categories of marks which are marked with ints range1, range2, range3 and range4, which are user enter digits. Part 1 of the code is to split the user entered digits into its correct ranges. the ranges are 0-29, 30-39, 40-69 and 70-100. I've done the part where when the user enters a digit, it goes into the correct variable. After that when the user enters a digit over 100, the enter results should show up as stars. For example

Enter number =

21
22
44
66
44
23
11
111 (the 111 is where the program breaks and moves on)

So it should then display

0-29 ****

30-39

40-69 ***

70-100

Whatever I'm trying, it displays an infinite amount of stars. If I try to use break, It only outputs a single star, no matter how many digits I enter

Here is the code

int mark = 0;
int range1 = 0, range2 = 0, range3 = 0, range4 = 0;
int count1 = 0, count2 = 0, count3 = 0, count4 = 0;
while (mark >=0 && mark <=100) {

[Code] .....

"The problem is with the while loop, the one above is something I was experimenting with "

Unable To Print Out Results Of Program That Calculate Number Of Seats

Nov 11, 2014

I'm trying to print out the results of a program that calculates the number of seats the parties will get in an election.I have to print the partial results and the national results.

I can print te number of seats per party in each constituency, but how can i sum all seats per party in each constituency and print the national results?I'm working with vectors, which I know it might not be the best option, but everything is working, except the fact that I can't loop throuhg the vector and retrieve the total sum per party.Like, adding the seats for labour party in Constituency A and B and C, etc, and print the sum. And do the same for conservative party.Is it possible, or doIhave to create a method in Parties class to solve the problem?

This is what I have now.

for (Parties p : h.geral) {
show += String.format("Constituency - %5s - %5s - %d%n",
p.getConstituency(), p.getParty(), p.getNum_seats());
}

Trying To Display Array Results In GUI Window JAVA

Sep 16, 2014

I am having the hardest time trying to figure out how to display an array in a 1-window GUI.

I can display 1 book separately, by basically ignoring the array and creating a new object for each book, but I need all 5 books to display in one window, and that's where I'm lost. I'd really like to use the arrayI built to generate the books in the GUI. The information of each book appearing horizontally, and the different books appearing vertically.

// Bookstore.java
// This program displays information on multiple books

Servlets :: Next Button And Retrieving Name Of JSPs

Feb 21, 2014

I want to have a button in my Jsp's labeled "next" that takes me to the next JSP in a certain order. Imagine a book: every time you click next you go to the next page.

Each page is a JSP that is named "page#" where # stands for the number (page1, page2,etc).

I was structuring my app this way: one controller,one controllerhelper,multiple JSPs.

The "next" button in the JSP's would always have the same name as not to overcode in my controllerhelper with too many options for the button that was pressed.

So my idea was to retrieve the name of the current JSP and work the string in order to add a number (page4 turns into page5) and forward it through a requestdispatcher.

That is the problem as I am not able to get the name of the current JSP since the url changes after the first page to the servlet url.

Swing/AWT/SWT :: Null Pointer Exception When Retrieving Data From Table

Mar 31, 2015

I am trying to export data from a jtable to a pdf report but every time i try running the code it gives me this exception:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at GUI.QC_receiving_book.printButtonActionPerformed(QC_receiving_book.java:309)
at GUI.QC_receiving_book.access$600(QC_receiving_book.java:26)
at GUI.QC_receiving_book$7.actionPerformed(QC_receiving_book.java:165)
at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2018)

[Code] ....

I tried avoiding the null exception by using the if statement but it didn't work. The row I choose from the table is full meaning there are no empty attributes. and all the data are imported from a mysql database to the table as String so there can't be any casting errors.

This is the part of the source code with the problem and i will also post the printing method. I tried debugging the class and when stepping into the first if statement it opened the jTable.java file and pointed at the getSelectedRow() method and this sentence "variable information not available.source compiled without -g option"

private void printButtonActionPerformed(java.awt.event.ActionEvent evt) {
if(samplesTable.getSelectedRow() >= 0){
int row = samplesTable.getSelectedRow();
System.out.println(row);
for(int x=0;x<samplesTable.getColumnCount();x++){
String value = samplesTable.getModel().getValueAt(row, x).toString();

Retrieving Result By User Input Different Combination Using String Tokenizer (MYSQL)

Mar 30, 2014

I am creating a simple Symptom Checker application. The problem I have is that I'm trying to retrieve user input (JTextField) by comma's using StringTokenizer which contacts the database for a result which matches the user's input (SELECT * FROM DIAGNOSIS WHERE ?, ?, ?) . It successfully finds the correct result however only in a particular format. Not different combinations....

for example, if I enter say within the JTextField: "tearful, nausea, lack of motivation" it will find the result successfully (as that is how it is formatted within the particular column (in the database table) i wish to display a result from) however, if i enter a different combination of these symptoms: "nausea, lack of motivation, tearful" - it will not find any result. I'm very unsure how to make it work regardless of what is inputted first, second or last.

Here is the code:

public void actionPerformed(ActionEvent e) {
try {
String abc = fieldsymp1.getText();
StringTokenizer str = new StringTokenizer(abc);
while (str.hasMoreTokens()) {
str.nextToken((", ")).trim();
