I am making a program, where the user answers 3 questions and then I add the number of correct answers in to the (int) numberofcorrect variable, then I want to print the results, and no matter how many correct, the program executes first the correct if statement, then the else statement.
Eg: I have 2 correct it will print:
"Grade B, 2 of 3 "
"You failed the test"
Why does it do that? How can I change my code so the else statement dosent print if one of the if statments is allready printed?I want to know how to not execute the else statement, if one of the if statements have allready been executed.Below is my current code for this problem:
if (numberofcorrect == 3){
System.out.println("Grade A, full score");}
if (numberofcorrect == 2){
System.out.println("Grade B, 2 of 3 ");}
if (numberofcorrect ==1) {
System.out.println("Grade C, 1 of 3");}
else {
System.out.println("You failed the test"); }
I want to execute my jsp code to compare two dates after every 10 seconds if user enter date and current sys date are equal it will send the mail to the user automatically. Below is my jsp code
this if condition i want to check the date after every 10 seconds and when two dates are equal it will send the mail using below mail code
if(ExpcReDt.compareTo(dateStr)>0) { out.println("Expected return date is greater than current date"); } else if(ExpcReDt.compareTo(dateStr)==0)
//Main method public static void main(String args[])throws IOException{ boolean runProgram = true; Scanner keyboard = new Scanner(System.in); //runs program while runProgram is true while (runProgram){
public class Main { private static void foo(Integer a) { System.out.println("Integer"); } private static void foo(long a) { System.out.println("long");
[Code] ....
This code prints long. Why is that? How did compiler decided that it likes long version of foo() method the most. If I had to guess I'd pick int... or possibly Integer as they are most similiar to what was passed. But why long?
I am unable to run this java mail code, whats the error!!
public class Class1 { final String senderEmailID = "from@gmail.com"; final String senderPassword = "password"; final String emailSMTPserver = "smtp.gmail.com"; final String emailServerPort = "465"; String receiverEmailID = null;
[Code] ...
I get an error as this
javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465, response: -1 at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1949) at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:654) at javax.mail.Service.connect(Service.java:317)
I want to execute and use the Win7 Speech Recognition with Java. How can I open it?
I tried to open it with "Runtime.getRuntime().exec(" ");" but I couldn't find a command to open it. How can I use the speech recognition once I opened it with commands in Java?
Question : How to execute batch file & .exe file using jsp servlet?I am giving input for blast in the FASTA format. After that i wants to make the sequence.FASTA file in my project folder. And I wants to execute batch file with parameters as blastp.exe file, sequence. FASTA file, database files, output file.
There is no problem in the file creation of sequence.FASTA
ERROR IN: the batch file is not execute, So the I am not able to get the output file for display.
ERROR is : java.io.FileNotFoundException: D:vaibhav_workspace.metadata.pluginsorg.eclipse.wst.server.core mp4wtpwebapps oxin-dataoutputprotein.txt (The system cannot find the file specified)
Technologies Used :JSP,Servlet,Process-builder
I have the following code as :
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); PrintWriter out=response.getWriter(); String values=request.getParameter("t1"); ServletContext servletContext = request.getSession().getServletContext(); servletContext = request.getSession().getServletContext(); String path="//sequence.FASTA"; /*file is created in getRealPath()*/
There are multiple .CSV files (each file has multiple rows and columns). I need to fetch data from all the files and find MEDIAN of the values for each column and do further calculations. Suppose there are 3 files, i need to find the MEDIAN of column 1 in file1, MEDIAN of column 1 in file2, MEDIAN of column 1 in file3. Below code just fetch data from one file.
I have few queries regarding compiling v/s execution of a java program. Suppose I have a Main Class which is referring to class Test which is present in JarA. Now, at compile time, this jar JarA must be present in classpath/buildpath. So, what actually is the action performed by the compiler by referring to this jar?
Now, at runtime also, this jar should be present to execute the Main class. Is this correct? If yes, then what is the action performed by JRE when it refers to this class at runtime? WOn't all the dependencies be resolved at compile time only?
Please enter 1 if your package is a letter and 2 if your package is a box 2 Please enter weight in pounds (Example: 1.2): 1.2 Please enter your shipping service option: Press 1 for Next Day Priority: Press 2 for Next Day Standard: Press 3 for Two Day Shipping: 1 7.00
If I comment out the else statement on the last line of code I get the following output:
Please enter 1 if your package is a letter and 2 if your package is a box 2 Please enter weight in pounds (Example: 1.2): 1.2 Please enter your shipping service option: Press 1 for Next Day Priority: Press 2 for Next Day Standard: Press 3 for Two Day Shipping: 1 13.75
What I want to happen is the code under the first comment to to execute if true, or go to the code under the next comments and execute if that statement is true and if that is not true I want the last block of code to execute underneath the last comments.

public class ComparativoV3{ public void loadComparative(String path){ } public void compareDbs(){
[Code].....
how to set it up the private void CompareActionPerformed(java.awt.event.ActionEvent evt) as the ComparativeV3 main class, not giving it any argument, because the files are load from the arguments section & it reads diferent files with diferent arguments.
I am having an issue where the code does something very strange when run. Everything seems to be ok in the code but I don't know what is wrong as no error is given.
Here is the code:
import java.util.Scanner; public class Pizza { private static int pizzaSmall = 10; private static int pizzaMedium = 12; private static int pizzaLarge = 14; private static int costPerTopping = 2; /**@return The total cost of the pizza when given the pizza size and the toppings.*/
[Code] ....
And here is the console output:
Please enter the number of Cheese toppings that you would like: 1 Please enter the number of Pepperoni toppings that you would like: 1 Please enter the number of Ham toppings that you would like: 1 Please enter Small for a Small Pizza, Medium for a Meddium Pizza, and Large for a Large Pizza: The number of Cheese toppings is 1. The number of Pepperoni toppings is 1. The number of Ham toppings is 1.
I am in the process of creating a calculator GUI that calculates different answers based on inputs two main comboboxes and numbers in the appropriate textfields. The first one allows the user to choose from 18 different materials, while the second has the user choose between two different shapes. In a brief word explanation, here's how it's set up:
User chooses material. User chooses shape. User types in appropriate values. 'Calculate' button clicked. If shape = rectangle, execute rectangle calculation. Else if shape = cylinder, execute cylinder calculation.
Everything works just fine with zero errors on all 18 materials and all kinds of decimal numbers when the second shape is selected. So the math and layout is solid. However, when the first shape is selected, it returns a $0.00 answer regardless of the input values (still no red-line errors). In efforts to troubleshoot, when I have /* Cylinder section */, the rectangle section works to a 'T'. This, I believe is caused by poor formatting in the syntax of the 'if' 'else if' in regards to the shape combobox.
//If 'Rectangle' is selected: if(shapeDropDown.getSelectedIndex()==1) { //6061 if(materialDropDown.getSelectedIndex()==0) { String msg0 = "The price is: $" + currencyFormat.format((0.098*(number2*number3*number4)*3.06)); totalPrice.setText(msg0);
What I'm trying to do below is to say if (adultTickets > 0) I want to bypass the studentOAP tickets question and go straight to the question about dinner. But if (adultTickets ==0) I want to go to the studentOAP question and then if the (studentOAPTickets >0) to go to the question about dinner. But if the (studentOAPTickets ==0) I want to go straight to the question about the contact number.
System.out.print("How many adult tickets do you require? "); int adultTickets = 0; boolean validAdultValue = false; while (validAdultValue == false) { if(aScanner.hasNextInt())
My initial question had to do with looping but now I'm having trouble adding certain variables.
The original thread is here: [URL] ....
If you look at the end of the code it won't recognize the "overtime" and "hourDiff". I have to use it for each level the user chooses and am not sure how to do so. Even if I put it under the if{ statement it won't calculate. I assume it's due to it being cut off from other blocks but I'm not sure how to combine them.
My code is:

I need to create a while statement for random computer moves.
I'm doing some revision for my OCAJ atm, & I came across this code in a mock question which takes two int arguments & simply returns the larger.
public int max(int x, int y){ if (x > y) return x; return y; }
When evaluating it I thought this would be invalid code as would always return x. But it transpires I was way off & that this actually works! In playing around with it, it seems like the first return statement is treated as:
if {// this bit } & the second return is treated as: else{ //this bit}.
What baffles me though is that you can put any amount of additional statements before the second return and it continues to work, however if you put even a single statement before the first return, the whole thing falls over.
I guess my two questions are - Am I right in my discovery above ( that statements preceeding the first return will always break it)? & secondly is this a good way of coding? for readability, I would always do it as:
public int max(int x, int y){ if (x > y){ return x; } else{ return y; } }
