Using an arrayList to create a menu and using a text file as input(bufferedReader)

As you can see below I tried creating a switch case for choices
1. Name
2. Course then Name
3. Year Level then Name
4. Course then Year Level and the Name
5. Exit
I don't know how to use switch case so that I could sort everything according to the menu. I will be using comparable and I am only allowed to edit the method called compareTo. My mind is blank and I got no idea where to start.

All programmers need to learn how to debug their code. If you are using an IDE then I recommend that you learn how to use its debugger.
You have some calls to method readLine() that you do not need. In the below code, I have marked these lines as comments. I also incorporated the methods display_array() and main() into class Student just so everything would be in the one class, but you don't have to do that.
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;

public class Student {

private char gender;
private int yearlevel;
public Student(String id, String ln, String fn, char g, String cors, int yl) {
studentid = id;
lastname = ln;
firstname = fn;
gender = g;
course = cors;
yearlevel = yl;
}
private static void display_array(Student[] v) {
for (Student s : v) {
s.display();
}
}
public void display() {
System.out.println("Name : " + lastname + ", " + firstname);
System.out.println("Student ID: " + studentid);
System.out.println("Course : " + course);
System.out.println("Gender : " + gender);
System.out.println("Year Level: " + yearlevel);
}
public void setGender(char gender){
this.gender = gender;
}
public char getGender(){
return gender;
}
public void setLastname(String lastname){
this.lastname = lastname;
}
public String getLastname(){
return lastname;
}
public void setFirstname(String firstname){
this.firstname = firstname;
}
public String getFirstname() {
return firstname;
}
public void setStudentId(String studentid){
this.studentid = studentid;
}
public String getStudentId(){
return studentid;
}
public void setCourse(String course){
this.course = course;
}
public String getCourse(){
return course;
}
public void setYearLevel(int yearlevel){
this.yearlevel = yearlevel;
}
public int getYearLevel(){
return yearlevel;
}
public static void main(String[] args) {
try (BufferedReader br = new BufferedReader(new FileReader("c:\\student.txt"));) {
char g;
int yl;
int i;
String ln;
String fn;
String id;
String cors;
Student v[] = new Student[Integer.parseInt(br.readLine())];
// br.readLine();
for (i = 0; i < v.length; i++) {
id = br.readLine();
ln = br.readLine();
fn = br.readLine();
// g = (char) br.read();
g = br.readLine().charAt(0);
cors = br.readLine();
yl = Integer.parseInt(br.readLine());
// if ((br.readLine()) != null)
// br.readLine();
v[i] = new Student(id, ln, fn, g, cors, yl);
}
display_array(v);
}
catch (FileNotFoundException e) {
System.err.println("File not found");
}
catch (IOException e) {
System.err.println("Unable to read the file.");
}
}
}
I also changed file student.txt. According to your code, the first line of the file needs to be the number of students in the file. In the sample file in your question, there are four students.

Testing (if..Else if...Else) statement (not working)

Testing an if else statement that does not seem to be working
Assuming it has something to do with possibly changing the IF else to the getter instead of setter?
or something to do with the variable returning an INT instead of string?
little confused been rearranging and modifying this code for a while now and cant get it to work

}

The code you have pasted require some changes actually.Assuming you need to return the discount percentage based on the customer input you need to do the following changes.
1) You have a setCustomerDiscount in Person class but the entity you are dealing here is of Customer type so you need to add the setCustomerDiscount in the Customer class instead of Person class.
2) As you want to show the percentage in String(as per your sysout statements/ you can also change to Int as required) you need to change the return type to String instead of Int.
3) Another thing is your order of the if/else if conditions should be in descending order.
Once you fix them, you can get your output as expected.
Below I have made those changes:
import java.util.Scanner;
class Person{
private String name;
private String address;

Hope it helps...

I think it is a logical problem. Simply order the discount formula in reverse.
Catch the big numbers first:
if r >= 2000 print 10%
else if r >= 1500 print 7%
else if r >= 1000 print 6%
else if r >= 500 print 5%
else print nothing
I hope that helps you

Java Program Unable to receive the input and program terminated prematurely

I'm not sure y this coding is not receiving the input for the adjust variable and gets terminated before it runs completely
public class Question {
int id;
String name;
String type;
double amt;
public Question(int id, String name, String type, double amt) {
this.id = id;
this.name = name;
this.type = type;
this.amt = amt;
}
public static void main(String[] args)
{ }
}
import java.util.*;
public class Answer {
public static void gettype(Question[] q,String adjust)

}
}}

q[i]= new Question(id,name,type,amt);
}
adjust=s.nextLine();
a.gettype(q,adjust);
}
}
While running the code i am able to get the inputs for the car object array.But after that i am not able to get the values for the variable adjust.
So please need help with this one.
I have tried simply to print the objects at the constructor side.
But not able to receive the 9th input which will be assigned to the var adjust

I think this is better. You should understand why mine works.

return sb.toString();
}

Inputting data into an object

I'm doing a homework assignment, where we were asked to create a banking system. The first option is to create a customer and to store their information in a customer object. The start of my create_customer() method asks for their name and stores it into a newly create Customer object, but when i call the getName() method, nothing comes back. Here's the initial class Atm which holds all the actions for each option.
import java.util.ArrayList;
public class Atm
{
private ArrayList<Customer> cust;
private int starting_account_number;
private int starting_customer_number;
private String admin_pin;
private int interest_rate;
private int transaction_counter;
ConsoleReader console = new ConsoleReader(System.in);
public Atm() // constructor
{
cust = new ArrayList<>(100);
starting_account_number = 1001;
starting_customer_number = 101;
admin_pin = "abcd";
interest_rate = 5;
transaction_counter = 0;
}
void create_customer()
{
Customer customer = new Customer();
System.out.println("Please input your name: ");
customer.setName(console.readLine());
customer.getName();
while (customer.istrue)
{
System.out.println("Please input a 4 digit alphanumeric PIN: ");
customer.setPin(console.readLine());
if (customer.istrue == false) break;
}
System.out.println("A system generated ID was created for you, it is: ");
String customer_id = String.valueOf(starting_customer_number);
customer.setId(customer_id); // set customer ID
starting_customer_number++; //incrememnt customer ID
System.out.print(customer.getId());
cust.add(customer); //puts the customer object into atm class arraylist
}
Here's the customer class
import java.util.ArrayList;
public class Customer
{
public boolean istrue;
private String name;
private String id; // 3 digits string
private String pin; // 4 digits string
private ArrayList<Account> acct;
private double total_bal; // for all accounts
public Customer() //constructor
{
acct = new ArrayList<>(100);
istrue = true;
name = "NoName";
id = "000";
pin = "0000";
total_bal = 0;
}
// public cal_total_bal() { }
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getPin() {
return pin;
}
public void setPin(String pin) {
this.pin = pin;
if (pin.length() != 4)
{
System.out.println("That was not 4 digits, please input a 4 digit alphanumeric PIN: ");
}
else istrue = false;
}

You are calling a method
customer.getName();
But you are not actually doing anything with it.. you might want to print it:
System.out.println(customer.getName());

java.util.Scanner; vs JOptionPane; [closed]

Closed. This question needs details or clarity. It is not currently accepting answers.
Want to improve this question? Add details and clarify the problem by editing this post.
Closed 8 years ago.
Improve this question
Please I would like know How would I implement JOptionPane instead of import java.util.Scanner;
I also have 4 separate classes
If i implement JOptionPane will it clean up the code I would also like to know any changes anyone would make.

Start by taking a look at How to Make Dialogs...
What you basically want is to use JOptionPane.showInputDialog, which can be used to prompt the use for input...
Yes, there are a few flavours, but lets keep it simply and look at JOptionPane.showInputDialog(Object)
The JavaDocs tells us that...
message - the Object to display
Returns:user's input, or null meaning the user canceled the input
So, from that we could use something like...
String value = JOptionPane.showInputDialog("What is your name?");
if (value != null) {
System.out.println("Hello " + value);
} else {
System.out.println("Hello no name");
}
Which displays...
Now, if we take a look at your code, you could replace the use of scan with...
public static String getInput(String inputType) {
String input = JOptionPane.showInputDialog("Enter the " + inputType + ": ");
return input;
}
As an example...
Now, what I might recommend is creating a simple helper method which can be used to prompt the user in a single line of code, for example...
public class InputHelper {
public static String promptUser(String prompt) {
String input = JOptionPane.showInputDialog(prompt);
return input;
}
}
which might be used something like...
String value = InputHelper.promptUser("Please enter the hours worked");
hours_ = Double.parse(value);
And this is where it get's messy, as you will now need to valid the input of the user.
You could extend the idea of the InputHelper to do automatic conversions and re-prompt the user if the value was invalid...as an idea

It is much easier than you think, if you try. Get used to reading the Java API.
http://docs.oracle.com/javase/7/docs/api/javax/swing/JOptionPane.html
Even has examples.
String input;
JOptionPane jop=new JOptionPane();
input=jop.showInputDialog("Question i want to ask");
System.out.println(input);
