While Statement Help

Hey, I'm having a problem with my while statement. I need to be able to have the program stop running when the input is Q. The only problem is that the input should otherwise be a number. I have to convert the user inputed number of dollars to euros using a previously inputed rate. So I can't just put everything as a String because then the equation doesn't work. Any help is welcome.

Any help is welcome.A handy thing to do when solving ANY programming problem:
1. Understand the problem, and what it is you have to do.
2. Think of a solution in terms of english (or whatever your language may be)
3. Put that solution into pseudo-code, which is often easier than working out what Java classes you might need.
4. Take that pseudocode and code it in Java.
Apply that to your current situation and the while loop should sort itself out.

Problem with while statement :(

i am having a problem with my while statement, can anyone help me to get it working :(
i am trying to get the while statement to only run when the input hasnt been a yes or a no, can someone please help me.
    System.out.print("Are you a Resident? (yes/no): ");
    Resident = console.next(); //Requests resident status from user and puts in in Resident
    while ((Resident != "yes") && (Resident != "no"))
                System.out.print("error - You didnt type yes or no. Try again: ");
                Resident = console.next();
            }

while ((Resident != "yes") && (Resident != "no"))Don't compare Strings with ==, use the equals() method instead.
while(!("yes".equals(Resident) && "no".equals(Resident)))

While statements

Hi All. I am a student in java programming, beginning class. I am having problems with understanding how to make a loop body work properly using a while statement. I have a problem I am working on, and I can't seem to get it to run properly, and I believe its mainly because I don't understand what I am doing. I have been searching the net for examples of while statements, but all I find are mostly the same ones, and they don't help. Here is the code I have so far, which compiles fine, but does not return the value I want, and also it seems to run infinately. Any ideas or help with this concept would be greatly appreciated.
public class StereoPayments
public static final double INTEREST_MONTHLY = 0.015;
public static final int PAYMENT_MONTHLY = 50;
public static void main(String[] args)
//Need variables for monthly interest amount, for amount left over from $50 payment minus inerest(which gets
//subtracted from the principle.
double startMoney = 1000;
double monthsInterest = 0;
double moneyAfterInterestPayment = 0;
double numberOne = 0;
double numberTwo = 0;
System.out.println("Here is your payments");
while (startMoney >= 0)
moneyAfterInterestPayment = (startMoney*INTEREST_MONTHLY);
numberOne = (moneyAfterInterestPayment + startMoney);
numberTwo = (numberOne - PAYMENT_MONTHLY);
monthsInterest++;
System.out.println("Months of payments " + monthsInterest);
System.out.printf("Amount of interest paid " + numberOne);
I am trying to print out how long it took to pay off the stereo, at $50 a month, while adding the interest to it each month, then output the amount of months it took to pay it off, and the total amount of interest paid. I am obviously not doing this right though. Can anyone help me? Thanks in advance! Newbie101.

System.out.printf("Amount of interest paid " + moneyAfterInterestPayment);
Here is a revised code. It does end now, thanks to you folks' help! However, I am failing to add up the interest amount. What is does is show how much interest is being paid monthly, but not adding it up to a grand total. So, would I make a statement of "moneyAfterInterestPayment++; ? Newbie101.

Programming a times table with FOR, WHILE & DO WHILE STATEMENTS

Guys,
Help me, I have tried hard, but I didn't find the answer, my problem is that I got difficulties in doing a times table with the FOR, WHILE, and DO WHILE STATEMENTS just using a single index or a single variable.
Guys, is it possible to program a times table with these conditions all together in the same code???
Do I await your suggestions?
Ps: Below, the attempt that I did, but I was not successful.
import javax.swing.JOptionPane;
public class tab
public static void main(String args[])
int i;
String TimesTable= "";
int result=0;
do
for (i=0;i<=10;i++)
result=i*1;
TimesTable +="\n" + i + "x" + i + "=" + result;
//JOptionPane.showMessageDialog(null, "Times tables of " + i + TimesTable);
// TimeTable="";
// i=0;
// i=i+1;
// i=0;
while(i<=10)
i=i+1;
// System.out.println("2 x "+i+"="+2*i);
// i--;
}while(i!=0);
JOptionPane.showMessageDialog(null, "Times Table of " + i + TimesTable);
TimesTable="";
}

You can use the if block "if(i%10==9)" in this case.

When would I use an if, for or while statement in Small Basic and what is the difference between the three?

I have a Y9 Computer Science Exam next week and I know that this will probably be one of the questions on it so I need to know the answer. What is the difference?

An If statement executes once IF the statement is true:
If 1 = 2/2 Then
Textwindow.writeline("True")
EndIf
A While statement executes WHILE the statement is true:
While 4 = 2+2
'Will keep looping while it is true
EndWhile
A For statement loops a number in increment:
For i = 1 to 10
'Every time through, i gets bigger by one until it equals 10
EndFor
It is written: "'As surely as I live,' says the Lord, 'every knee will bow before me; every tongue will acknowledge God.'" Romans 14:11

While statement

Hi,
I have a while statement and within this a return statement, but when i compile this it produces an error -
missing return statement.
This is my code:
public double getResults() { // Open getResults method
while ( i >= 10 ) { // Open while
i++;
return (runs * 10);
} // Close while
} // Close getResults method
What is wrong?
Thanks

The compiler waits for the return statement to be at the end of the method. For example if you put it before your while loop you'll have an error like "unreachable statement". Because the compiler understands the return statement as the end of the method.
In your case:
What happens in any loop or statement is forgot after its end. So if you create a variable inside the loop and your try to change its value after the end of the loop, it will give you an error because any variable created inside the loop is erased from the memory at the end of the loop. The same thing happens to your return statement . If the value is returned in the loop, as the compiler understand it as the end of the method, it creates an error because the method is not finished yet. And as a previous user told you if the condition of the while loop is not met the return will not be executed. But the compiler is not so smart, it just waits for the return statement as the last line of any such method. And as the value you are returning is declared outside the loop, it will keep its new value at the end of the loop, so you will return the value you want.

How Do You "Unload" Using a "While" statement?

How do you "Unload" or "Exit" using a "While" statement?
Sample: The console displays "Press Enter to continue".
Description: It a User press the Enter key, then the application would start over. On the other hand, if a User presses the "0" key, the application ends, exits. What code would be used?
THANKS ... signed ... VERY NEW at JAVA ...

input=readInput();
while (input!=yourExitKey)
// do stuff here
input=readInput();
// End of code

URGENT! Having problem with while statement and other syntax errors

I am trying to teach myself JSP for a school project due very soon. But I keep receiving errors surrounding my while statement. The errors are:
Syntax: ";" inserted to complete BlockStatements
Syntax: "}" inserted to complete Block
I have checked it over and over again, comparing against other examples found in this forum and against servlet examples and I can see no difference. This is my file for your information. It is supposed to list all the users in the user table. Is there a simpler way to do this?

There is a problem here with the "scope" of variables namely your variables "rs" and "stmt". Variables declared within a try block are available only within that try block. Also, the type for stmt is not even given.
Change:
try{
//create SQL statement
stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * from USER ORDER BY User_lastname, User_firstname");
catch(SQLException e){
System.out.println("Error connecting to the database.");
System.out.println(e.toString());
throw new UnavailableException(this, "Cannot connect to the database");
}to:
Statement stmt = null;
ResultSet rs = null;
try
    //create SQL statement
    stmt = con.createStatement();
    rs = stmt.executeQuery("SELECT * from USER ORDER BY User_lastname, User_firstname");
catch(SQLException e)
    System.out.println("Error connecting to the database.");
    System.out.println(e.toString());
    throw new UnavailableException(this, "Cannot connect to the database");

Problem interpreting a while statement

Hello there,
The following code snippet (excerpted from Thinking in Java) has held me down all day. Can anyone tell me what condition evaluated to true in the while statement?
import java.io.*;
public class FormattedMemoryInput
public static void main(String[] args) throws IOException
     try
        DataInputStream in = new DataInputStream( new
                     ByteArrayInputStream(BufferedInputFile.read(
                                 "FormattedMemoryInput.java").getBytes()));
       while(true)
        System.out.print((char)in.readByte());
     catch(EOFException e)
       System.err.println("End of stream");
} Thanks,
ue_Joe

Do not mind me. I am just as confused with the concept as with interpreting the statement. Here's the other half of the code. Might wish to run it to see that it works.
// BufferedInputFile.java
import java.io.*;
public class BufferedInputFile
// Throw exceptions to console:
public static String read(String filename) throws IOException
    // Reading input by lines:
    BufferedReader in = new BufferedReader(new FileReader(filename));
    String s;
    StringBuilder sb = new StringBuilder();
    while((s = in.readLine())!= null)
      sb.append(s + "\n");
    in.close();
    return sb.toString();
public static void main(String[] args) throws IOException
    System.out.print(read("BufferedInputFile.java"));
}ue_Joe.

So I'm pretty new to Java programming and I cannot seem to understand why this is not looping if the user inputs a "n" at the end.

Help with MYSQLi Query and WHILE statement

Still getting the same issue.
As I see it, the way you have suggested is just rearanging things right?
here is a screenshot of the outcome:
And here is the improved code:
<?php
//Main Connection & Query
//Database Connection & Error
$con_host = 'X';
$con_username = 'X';
$con_password = 'X';
$con_database = 'X';
$con = new mysqli($con_host, $con_username, $con_password, $con_database);
?>
<?php
//Query
$sql = "SELECT * FROM equipment ORDER BY name ASC";
$result = $con->query($sql);
$row = $result->fetch_assoc();
$row_count = $result->num_rows;
//Create Variables
$name = $row['name'];
$size = $row['size'];
$quantity = $row['quantity'];
$protection = $row['protection'];
$location = $row['location'];
$sublocation = $row['sublocation'];
$bc = $row['BC'];
$id = $row['id'];
?>

Nested While Statements

Hey guys,
Im fairly new to Java programing and i have hit a brick wall in my coding.
My program is a Multi-choice questionaire. And all works fine until i add the error checking code in, and i dont get (and I can't get to work) nested will statements.
Could you guys help me merge these to Statements:
while(!in.hasNextInt())       //This part works fine
{                                             //This is to check if the user put in a interger.
in.nextLine();
System.out.println("\n Invalid Selection!");
System.out.println("Please Enter Amswer \n" );
}and this part i cant get this part to work correctly
if (Userinput >5 || Userinput <0)    //This is ment to set parameters so that
{                                                            //the user can only enter the numbers
in.nextLine();                                      //between 1 - 5
System.out.println("\n Invaild Selcetion");
System.out.println("Please Enter Answer\n" );
Userinput = in.nextInt();
}I would like to have both sections of code as 1 section so that it checks for both errors before it continues throught he rest of the code.
any help would be greatly appreciated.
if you want to email me or get me on msn:
brokenstaff at gmail dot com
again thanks.

ok, well that is a very complex section =)
well i tried it, but that numer validator still wont allow numbers under 5 ??? i dont know why. It works in the way of giving the error message when entering a char.
any way here is the full code with code inserted:
PS the counter intilization well that is for later.
and you can proably already figure out why it is there. =)

There is no CASE statement in SQL; it is a CASE expression. Big difference.
Since SQL is a database language, we prefer to do look ups and not calculations. They can be optimized while temporal math messes up optimization. A useful idiom is a report period calendar that everyone uses so there is no way to get disagreements in the DML.
The report period table gives a name to a range of dates that is common to the entire enterprise.
CREATE TABLE Something_Report_Periods
(something_report_name CHAR(10) NOT NULL PRIMARY KEY
CHECK (something_report_name LIKE <pattern>),
something_report_start_date DATE NOT NULL,
something_report_end_date DATE NOT NULL,
CONSTRAINT date_ordering
CHECK (something_report_start_date <= something_report_end_date),
etc);
These report periods can overlap or have gaps. I like the MySQL convention of using double zeroes for months and years, That is 'yyyy-mm-00' for a month within a year and 'yyyy-00-00' for the whole year. The advantages are that it will sort with the ISO-8601
data format required by Standard SQL and it is language independent. The pattern for validation is '[12][0-9][0-9][0-9]-00-00' and '[12][0-9][0-9][0-9]-[01][0-9]-00'

GET pernr statement help

Hi,
I am a very much a beginner to ABAP.
Can anyone explain me the logic with which pernr statement works?
This is my understanding so far.
i think it is working as a loop.
At first loop it gets the record of first pernr number into an internal table. If muliple records exists they are added into the internal table.
This goes on for all pernrs.
Is this correct?
Also i think there is a table where pernr number is stored globally. This is because i get a pernr number while using get pernr but that number is nowhere in any table.
Can any1 tell me that table name.
Thanks in advance,
Bala
