Java Programming Project Involving Get And Set Methods?
Apr 4, 2014
1. Modify the following class so that the two instance variables are private, there is a constructor that accepts both the player's name and sport and there are get and a set methods for each instance variable:
public class Player {
String name;
String sport;
}
2. You can pass an instance of this class to the JLabel constructor if you want to display text in the label.Select one:
a. myLabel
b. myText
c. String
d. JTextField
e. JLabelText
how to start making this work?cause i am not familiar with the terms here and want to complete this program and I am new to java programming?
So I want the method getDisplayText of d to be returned as long as the for loop runs. When I do this I get a compile time error to enter a return statement. I am currently trying to fix it by returning an empty string, yet this doesn't seem the right way to go.
public static String displayMultiple(Displayable d, int count) { for(int i = 1; i <= count; i++) return d.getDisplayText(); return ""; }
I'm working on a project that involves the following:
-Creating a superclass of bankaccounts -Creating two subclasses, checkingaccount and savingaccount -Each of the two subclasses has different methods (writeCheck for checking, for example) -Both types are created in a main class bank and stored in the same array
So let's say a user goes through the menus and creates a few savingAccounts and a few checkingAccounts (stored in the accounts[] array). Then, to write a check from one account, the user can enter the account number (a string), and the method will use a for loop to cycle through the array until it hits an account number match. Then it checks that it's the correct account type and calls methods from the subclass.
Problem here is that some methods work and some don't. In the following example:
for (BankAccount account: accounts) { if (account.getAccountType().equals("Checking")) { do { if (account.getAccountNumber().equals(accountNumber)) { amount = Double.parseDouble(JOptionPane.showInputDialog(
[Code] .....
The getAccountNumber method works but writeCheck is throwing an error. I tried creating a method in the superclass and overriding it in the subclasses but with no success.
The goal is as follows: Write a UDP 'CompressionServer' that will take input from the user until it sees a "magic string" at which time it will create a compressed and uncompressed version of the file in the file system.
So, I need to integrate the following "Zip" code in to my UDP server code (which already creates the uncompressed file)... That is where I am stuck at now. My first few attempts had the Zip code after I write to "fout" but that failed to create a ZIP file.
I guess the main point here is what are the key pieces of the ZIP code that I should include and what would be the best spot to place them in my server code...
Zip Code:
import java.io.*; import java.util.zip.*;
public class Zip { static final int BUFFER = 2048; public static void main (String argv[]) { try { String fileInput = argv[0]; String fileOutput = argv[1];
We are working with Java and Eclipse..One of the assignments asks to "Write an application that determines the number of coins in a jar and prints out the total in dollars and cents. Read integer values that represents the number of quarters, dimes, nickels and pennies. Use a currency formatter to print the output."
I would like to bring a project in java program written by me, that interfaces with a fingerprint reader (already purchased, the reader U.are.U 4000b) and as I'm using fingerprint sdk sdk's Griaule.
I have written a java code to transfer files from one server to another using the concept of socket programming. I got the codes from another java forum that meet my requirements. The program is said to transfer large sized files (like .mkv , .mprg movies) from one machine to another and can be used to transfer files of all formats. But after running the codes I found that the program is not able to transfer large sized files such as movies and even pdf of sizes 80mb or 111mb. When i transfer small sized files, it gets transferred and the output shows that. You can run the codes and observe it. But when i try to transfer large sized files, the program goes on running for hours. The large sized files are not getting transferred. The program has used bytebuffer but still this error occurs. The codes are as follows (I got them from this site [URL] ....)
**ClientMain.java**
import java.io.IOException; import java.net.Socket; public class ClientMain { private DirectoryTxr transmitter = null; Socket clientSocket = null;
[Code] .....
1. ClientMain.java and DirectoryTxr.java are the two classes under client application. 2. ServerMain.java and DirectoryRcr.java are the two classes under Server application. 3. run the ClientMain.java and ServerMain.java simultaneously
Also specify the source directory, destination directory and host address of the machine in which server is running in the ClientMain.java (as per your computer). Here we are not specifying source file, instead a source directory or folder is specifying. So the entire files of source directory will be transferred.
I have written this program but I am seeing error when I compile this program ( javac TestArithmetic.java).
1)TestArithmetic.java:26 cannot find symbol
2)symbol: class Arithmetic
3)location: class TestArithmetic
4) Arithmetic ar = new Arithmetic(x1,x2,x3);
1)TestArithmetic.java:26 cannot find symbol
2)symbol: class Arithmetic
3)location: class TestArithmetic
4) Arithmetic ar = new Arithmetic(x1,x2,x3);
2 errors.
Code :
import java.util.*; class TestArithmetic { public static void main (String[] args){ float number; Scanner console= new Scanner (System.in); System.out.println("Enter first number");

I am new to java and do not understand how to use filters very well. I need to write a code that determines if an integer is not divisible by some value. A filter also contains an upstream filter so that this filter can be part of a chain of filters.
I am new to java programming and using bluej for programming and i have tried this question what i have have given in title ... how to find out the errors in the following program:-
class Primedig { public void getinput(int n) { int ctr=0; while(n!=0) { int r=n%10; for(int i=1;i<=r;i++)
[code] .....
output:-
For example input is 243 the output comes only 3 not 2& 3 both.

I tried many times to return a string from java project to an android project But it keeps sending incorrect values as in 2 as it should be 1 here is an example.
I use a program called eclipse. I want to know how to build a house with the program. We use a pen in java. It is a drawing tool. I dont know how to do it.
I should do, for my academic project, draw from a java project some information, for example, the class name and the relative method, and for each class even the package name where the class is. The information found must be saved an XML files...
I have a gameengine stil partially in the works for pc made in java, I am attempting a port over to java but certain classes and other fuctions are not available for android that there is in java. this means that my render engine, gameengine and a couple of other clases therefore don't work.
My question is, is there anyway of using the gameengine classes that work into the project so that all i have to do is declare within the engine what i want to export for wheather this is android or java. or importing packages from the game engine project and directly linking with the ability of re-writing the odd few classes that do not work.
I want to develop a website using jsp and servlets.but i have a few questions:
