Totally New in Java - Please help!!

Hi Dear all,
l am totally new in Java, and l facing one problem,and really hope can get some help from yours,please!
l need to write this program:
The program should do the following:
1. Input two fields: action (action: add / delete), and account number (any
digit or character)
2. if the action is "add" then the program adds one text line to a text
file.
"New account is <account number>"
3. create the text file if it is not already exist (in c:\)
4. When program runs again with new input values, a new line will be
appended to the same file.
5. if the action is "delete" then the program finds the record and removes
the text line from the file.
My problem is :
l just know that l need to create the user interface first,but l don't know how to go on??
Would you please show me some step how to solve these problem?
Many many thanks!!

I don't know about Swing. I never use it.
The stuff to create and manipulate files is in the java.io package.
You'll probably want to use java.io.FileReader and java.io.FileWriter.
Note that FileWriter has a constructor that lets you append and not overwrite.
I'll start you off with a test.
public class AccountListAddTest() {
public static void main(String[] argv) {
AccountList accts = new AccountList();
accts.add("abcdefg12345"); // arg is a hypothetical account number
}Write an AccountList class that'll work if you compile and run this test. After you run this test for the first time, the file should contain the string
New account is abcdefg12345.
This test assumes that the filename is hardcoded into the AccountList class. To keep it simple, make the add method create a new appending FileWriter each time, write, then close the writer.

Very new to java please help

Please, help me with file access in Java Applet.

Applets are not allowed to connect to other server
than the one they were loaded from. This is probably
the reason here.You mean that I can use the applet after uploading on my web-site and using "getDocumentBase()" only?
OK.
The applet works perfectly if I use that function, but I have another question.
If I want to use something like:
Img1=getImage(getDocumentBase(), "s01.jpg");
it works perfectly.
If I do the fillowing:
Img1=getImage(getDocumentBase(), "pic/s01.jpg");
it also works.
But is it possible to go a level up?
Like:
Img1=getImage(getDocumentBase(), "../pic/s01.jpg");
That is if an applet is in one folder and the pictures are in another, but to get to them I have to go a level up and then enter another folder.
Please help.
Thanks.

New To Java Coding, Help NEEDED With a little script

Well im just working on a script with an open uni course im doing, ive dont the script i was asked to do, but i was wondering if i could expand it abit more
* The DaylesGod class implements an application that
* simply prints "Dayles God!" to standard output.
class DaylesGod {
    public static void main(String[] args) {
        System.out.println("Dayle is GOD!"); // Display the string.
}thats what i have at the moment, i use cmd-cd C:\java
C:\java>java DaylesGod
Dayle is GOD
I was wondering if i could get it to display diffrent messages on diffrent lines? e.g
* The DaylesGod class implements an application that
* simply prints "Dayles God!" to standard output.
class DaylesGod {
    public static void main(String[] args) {
        System.out.println("Dayle is GOD!"); // Display the string.
        System.out.println("Dayle is GOD!");

}This code executes fine in Jcreator, but only once, it wont type ''Wow'' Twice? Not to sure what to do, it wont run in cmd properly, want multiple ''Wows'' on seprate lines. If possible? Thank you :) and i will get in touch with shrink ha.That should print

WowAre you sure you're not having a problem with Jcreator or whatever you're viewing the output with? You might try executing this from the command line. There's no reason you can't do that.
Remember, System.out.println(x) is equivalent to System.out.print(x + '\n').

New to java, please help me :(

hi, i have to complete a BMI calculator with arrays and switch, i need it so that if input a / b is selected it will calculate metric / imperial (i know that both calcs are the same, its just a placeholder for the time being). once thats selected users are asked to input name, age, height and weight, then looped again for another user to input into the array.
once completed the name and age along with the BMI calculation for all the users that have inputted are displayed
the problem is, the calculations are wrong, where it should be outputting a BMI of between 20-23ish im getting 0.3
i think i had this problem when i done the switch example previously, but to fix that i just lumped all the code (inputs and calcs) into each case. in this method im guessing that would be an incorrect approach ?

yush !
i done it :D
i just ended up lumping all the code into each case like i did last time, as when i had the calculations outside of the cases it wasnt taking the values from inside the case. nevermind....
another problem i do have though, i need a loop so that once the program finishes it repeats itself until an X is entered, im not very good with loops :S
i tend to try it like this
quit = 1;
while (quit<2){
then just have one of the cases as quit +1
so in mine it looks liek this:
int quit=1;
while (quit<2){
String input = JOptionPane.showInputDialog(
"Welcome to Chunks BMI calculator\n"+
"a) Metric.\n"+
"b) Imperial\n"+
"q) Quit\n"+
"\nPlease enter letter code" );
char code = input.charAt(0);
switch(code){
case 'a':
JOptionPane.showMessageDialog(null, "You have selected imperial. "+"\n\n" +" Thank you.");
for(int c=0;c<2;c++){
name = JOptionPane.showInputDialog("enter your name");
age = JOptionPane.showInputDialog("enter your age");
Hfeetstr = JOptionPane.showInputDialog("enter your Height in feet");
Hinchesstr = JOptionPane.showInputDialog("enter the remaining inches");
Wstonestr = JOptionPane.showInputDialog("enter your weight in stone");
Wlbsstr = JOptionPane.showInputDialog("enter the remaining lbs");
Hfeet = Float.parseFloat(Hfeetstr);
Wstone = Float.parseFloat(Wstonestr);
Hinches = Float.parseFloat(Hinchesstr);
Wlbs = Float.parseFloat(Wlbsstr);
Wlbs = Wlbs * 0.45359237;
Hinches = Hinches * 0.0254;
Hfeet = Hfeet * 0.3048;
Wstone = Wstone * 6.35029318;
bmiweight = Wstone + Wlbs;
bmiheight = Hinches + Hfeet;
BMI = bmiweight / (bmiheight*bmiheight);
String cat="";
if (BMI <18.5) cat = ("Posh spice");
else if (BMI >= 18.5 && BMI <=25) cat = ("Fit !");
else if (BMI >25 && BMI <=30) cat = ("Fatty !");
else if (BMI >30)cat = ("Super Fatty");
myItemArray[c].setcat(cat);
myItemArray[c].setname(name);
myItemArray[c].setyear(age);
myItemArray[c].setBMII(BMI);
break;
case 'b': output= "Metric.";
etc.....
this is causing me the problems:
for(int i = 0;i<2;i++){
myItemArray[i] = new Item();
says a non static variable cannot be referenced from a static context, i know im being stupid with my implementation, but whats a better way ?
thanks again :)

I purchased an audiobook in Nov 2012 using iPhone 4S and then upgraded to iPhone 5 in Dec. Now I am not seeing the audio book in purchase history in iTunes. This means I am not able to get the book in my new iPhone. Please help.

Audiobooks are currently a one-time only download from the store. If you don't have it on your computer (audiobooks go into the Books part of your iTunes library) nor on a backup, then if it's still in the store you can try contacting iTunes support and see if they will grant you a re-download : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page

Hi sanket chalke,
I'm not sure what Adobe product you need help with, but you might want to start with this document, which has deactivation information: Activation & Deactivation Help
Please let us know how it goes.
Best,
