How To Add Multiple OR Choices In If Statement
Jan 21, 2015
I have this very code:
if (minute > 35 && hosts < 1 && guests < 1)
In this if statement I would also like to add another two possibilities:
first would be: hosts < 1 && guests < 2
second would be: hosts < 2 && guests < 1
Is it possible to somehow add it so it can all be in included in one if statement, and it would look something like that:
if (minute > 35 && hosts < 1 && guests < 1 OR
minute > 35 && hosts < 2 && guests < 1 OR
minute > 35 && hosts < 1 && guests < 2) {}
.. ?

This program allows the user to select one of each different type of skateboard/accessories items. Then it allows the user to select as many misc items as he or she chooses. The program works fine for the single choices, but I cannot solve the latter part. I have a get method in the misc class that is trying to pull out any selection or selections that were made by the user, but it simply does nothing...
Here's my program, I have four panel classes for each skateboard type, and then I have one class that takes care of adding each panel to the content pane, and calculating the total cost of the item.
Decks Panel Class:
import java.awt.event.*;
import javax.swing.*;
// The DecksPanel class allows the user to selects a specific type of skateboard
public class DecksPanel extends JPanel
[Code]....

I'm using this try statement to check for errors in input in my Tic Tac Toe game. The problem I have having is I don't understand why this error is happening. It's preventing my code from compiling. I've tried inserting an else statement and multiple brackets at various places with no success.
Java Code:
public void play(){
Scanner input = new Scanner(System.in);
int row, col;
char currPlayer = 'X';

I am trying to execute the following method: This method takes a delivery date as one of the arguments and a list of calendar holidays as another argument. If the delivery date is present in the holiday list, I will add 1 day more to the delivery date and check again if the new delivery date is part of holiday list.
Issue is that the last 3 statements before 'return' are getting executed multiple times though there is no for or while loop. Why they are getting invoked multiple times.
@SuppressWarnings("rawtypes")
private String fetchNextWorkingDay(String sDeliveryDate, Element eleCalendarDayExceptions, SimpleDateFormat sdf, Format formatter) throws Exception {
System.out.println("");
System.out.println("Inside fetchNextWorkingDay method");
System.out.println("Del Date to compare is "+sDeliveryDate);
Boolean isDateSet = true;

I am experimenting with messages in JOptionPane and I was wondering why this program does not display anything when the choices are inputted.
*note: I tried putting "JOptionPane.showMessageDialog(null, "This is an information message", "Information", JOptionPane.INFORMATION_MESSAGE);" after the "int i = 0;" and then the messages displayed.
Scanner scan = new Scanner(System.in);
int i = 0;
while (i != 6)
{
System.out.println("1. Information message");
System.out.println("2. Error message");
System.out.println("3. Question message");
System.out.println("4. Plain message");
System.out.println("5. Warning message");
[code]....

I am stuck trying to build a relatively "simple" GUI. The GUI should have one JComboBox that allows the user to pick from one of three locations. Then based on their choice, another JComboBox should be generated with another set of choices. The key is that the second ComboBox should have different choices depending on the selection made in the first one. So, in theory, the logic should be something like:
//create new JComboBox array of strings "locations"
//create new JComboBox array of strings "costToTravelThere"
//if user picks location 1 from the first ComboBox
then add the second ComboBox with options specific to that first location
else if user picks location 2 from first ComboBox
then add the second ComboBox with options specific to that second locatoin
I understand how to do the basic stuff, like create the JFrame and the actual panels and ComboBoxes, etc. What I don't understand is how to implement the second ComboBox dependent on the first one. I'm not very experience with Listeners and such, and I'm sure that's a big part of this.

So from what iv learnt in Java and programming in general is that using a case statement is far more efficient that using multiple IF statements. I have an multiple IF statements contained within a method of my program, and would like to instead use a case statement.
public String checkPasswordStrength(String passw) {
int strengthCount=0;
String strengthWord = "";
String[] partialRegexChecks = { ".*[a-z]+.*", // lower
".*[A-Z]+.*", // upper
".*[d]+.*", // digits
".*[@#$%!]+.*" // symbols

I'm very new to Java, and I am creating a program that takes multiple user input to create one face. I have a class for the eyes, nose, lips, and headshape. For some reason, my program is not drawing the graphics. ***for question purposes, I have only included my head shape class and my test class****
my "test" class:
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
public class FaceTest
{
public static void main(String[] args)
{
String head = JOptionPane.showInputDialog("Would you like a circle, square, rectangle shaped head?: ");

I'm trying to run an if statement with an input condition and here is my code.
import java.util.Scanner;
public class App10A {
public static void main(String[] args) {
Scanner fun = new Scanner(System.in);
System.out.println("What's your name?");
String name = fun.nextLine();
[code]....
When the computer asked me "What's your name?", I typed in Victor, then the result turned out to be "Oops, try again!".I typed in Victor (without parenthesis) and "Victor" and both gave me the negative results.What exactly should I put in in order to get "This is the result I wanted!" ? how should I modify my code in order to get "This is the result I wanted!" when I put in Victor (without changing the equal sign)?

How do I use a variable in an if statement to return a public void method from another class? I've tried:
System.out.print("select 1 - 6: ");
Scanner myScanner = new Scanner(System.in);
myScanner.nextInt();
if (myScanner.nextInt()==1) {
carSelection colour = new carSelection();
colour.carSelection();
The method colour in class car selection is just 4 print line statements? I've // out the if statement to see if it is correctly calling the method and displaying the data and it is?

I'm having a problem where an if statement isn't working. In the Person class boolean olderThan ignores my if statement so it always returns false and I just don't get why that's happening.
import java.util.Calendar;
public class Person {
private String name;
private MyDate birthday;
public Person(String name, int pp, int kk, int vv) {
this.name = name;

In the program below I populated three arrays: student id, name, and GPA. The findStudent() method attempts to match users input with the input stored in the studentID array using an if/ else statement. When I use the if/ else statement the else always executes regardless if the IDs match? I am trying to get JOptionPane.showMessageDialog(null, "Incorrect entry"); to print only if the IDs don't match.
Java Code:
//FILE: StudentIDArray.java
import javax.swing.*; //Used for the JOption dialog boxes
import java.util.*; //Used for Scanner input
public class StudentIDArray {
boolean nameFound = true;
final int numOfElements = 2; //Final int to control to loop for data
[code]....

i'm confused about the if statement part because int i = 0 is set to zero but how can you get the remainder if int i is zero?
for (int i = 0; i < 200; i++) {
if (i % 12 == 0) {
System.out.println("#: " + i);
}
explain to why it output like this?
#: 0
#: 12
#: 24
#: 36
#: 48
#: 60
#: 72
#: 84
#: 96
#: 108
#: 120
#: 132
#: 144
#: 156
#: 168
#: 180
#: 192

I am making a simple calculator. I want the user to input either string "add" or "subtract" and then it will take two numbers and either add or subtract them. I cannot get the if statement to work with a string!

Scanner input = new Scanner(System.in);
System.out.println("Enter add or subtract");

I'm trying to make a test on java. So far I'm on Question 1 and I'm having this issue. The if else statement won't allow me to add to the score.
class ExamEngine {
static CinReader Cin= new CinReader();
static int Score=0;
public static void main(String[] args) {
System.out.println("Type in your name.");
String name=Cin.readString();
[Code] ....
If I remove the "Score++;" bit, everything is fine. But I need to add to the score when they answer a question right. However, with "Score++;" there, I get this issue: 'else' without 'if'.
Note that this cannot be multiple choice, so that's why I'm using if-else, because I don't think a case system would work here.
Is there a way I can make this work while adding to the score?

I've done a basic login GUI for a application, a user enters their name and address and clicks register, a four digit pin is then randomly generated, the pin and name and address are all added to an object of the MemberDetails class , this obj is then added to an array list.
returning customers can then enter a previously generated pin and either get a welcome back message or an invalid pin message.
my issue if i register two new users and get their generated pins, that on the returning members screen it will only show the welcome message for the second new customer i created and not recognizing the first customers pin. heres my code:
taking in new customer details, generating pin , adding obj to arraylist
int randomPIN = (int) (Math.random() * 9000) + 1000;
members = new MemberDetails();
members.name = nameNew.getText();
members.address = addressNew.getText();
members.pin = randomPIN;
[Code] ....
that lest method is a bit of a mess i know, i was going to store the log in attempts in a array but thats probly not a good tactic, and that inner for loop is probly unnecessary ?

I have two different Class object arrays storing 3 elements (2 Store arrays, both initialised to hold 3 Product objects). The problem is, I can set data to one array with no problem but my program doesn't want to set the data for my second array.
For instance, The main problem is this method:
public void addData(String store, String newName, int newDemand, double newSetup, double newUnit, double newInventory, double newPrice)
//Method that sets the data value for a product
{
if (store.equalsIgnoreCase("callaghan"))//!!!!Goes from this line in the debugger
if (noOfProductsCallaghan==0)
{
setData(product[0], newName, newDemand, newSetup, newUnit, newInventory, newPrice);
noOfProductsCallaghan++;
}
else if (noOfProductsCallaghan==1)

I am trying to get the program to ask the user to enter the project grade and if it is less than 65, then I want the program to display "fail" or if it is greater than 64 than I want it to display "passed". In this project I have to include a method and I am trying to call it in my if-else statement. I keep getting an error message saying "Project.java:143: error: incompatible types: void cannot be converted to int". I posted my code below. It's a long program, but this part is toward the bottom.
import java.util.Scanner;
public class Project {
public static void main(String[] args) {
//call method

When year is outside the 1993-2009 range, I get a NullPointerException from line 10. Shouldn't it be skipped entirely since the conditions of its parent IF statement (line 7) is not met?

I am having trouble doing a simple exercise changing a for loop to a while statement, it works fine in the for loop but in the while statement it just prints out 10(it is supposed to count to 0 and print liftoff).
public void run() {
int i = 10;
while (i>=1) {
println(+i+"...");
i--;
}
println("liftoff...");
}
