I'm not sure why, but my program does not produce an output. It is supposed to output total charges.
/*This program provides the user with the price of their monthly internet service based on two inputs.The program asks users which subscription they have. The options are A, B, or C. This is the first input.
The program then will ask the user how many hours they used the internet for. This is the second input.Then, based on the package number, the program will compute their monthly bill. This is the output.
The program calculates the price based on the following prices:
Package A: For $9.95 per month, 10 hours of access are provided. Additional hours are $2.00 per hour.
Package B: For $13.95 per month, 20 hours of access are provided. Additional hours are $1.00 per hour.
Package C: For $19.95 per month, access is unlimited.*/

I'm having some trouble with getting this program to read an input of morse code and then produce an output of English. When typing in morse code for the phrase 'the string', the output looks something like this:
I am working on a personal project and want to create a text editor to write my code. I am wondering how could I read the last input from the user and if say it was an open curly brace {, then like netbean's my editor will supply the closing curly brace. My java experience is limited but I have tried to read key board input and a few other options that did not work.
Write a function (or functions) that given a collection of files will produce a sum of integers from each line of each file. Each file can have any number of lines from 1 to N. Each line can contain only one integer and no other alphanumeric characters. All of the numbers from all of the files should be added to the final result. The result is just one number.
My program successfully reads a file, reports back what it finds and creates an output file. However, I cannot get it to write to the output file, it is always blank!
Here's my code:
import java.util.Scanner; import java.io.*; public class Ex19 { public static void main (String [] args) { //Variables
I wrote a program that find adjacent value for -1 .ex:
input 1 3 3 1 2 2 1 1 -1 5 5 0
output 1

Write a program to create an integer array of size 20. Then, the program should generate and insert random integers between 1 and 5, inclusive into the array. Next, the program should print the array as output.
A tremor is defined as a point of movement to and fro. To simulate it, the program will generate a random number between 0 and 19, which represents the location in the array (i.e. index number). Then, the 3 numbers to the left and right of this location should be reset to the value 0. If there isn't 3 numbers to the left and right you may assume a lesser number depending on the boundaries of the array.
Then, the final array should be printed as output. There is no user input for this program.Your program must include, at least, the following methods:
-insertNumbers, which will take as input one integer array and store the random numbers in it. -createTremor, which will generate the random number as the location and return it.
So I'm pretty much done with this project except I am unable to get the println statements of "Produced" & "Consumed" to display in my JTextArea on my GUI. I am completely lost as to exactly why the program just continues to create new windows repeatedly crashing. I will include the code to the 3 classes I'm working with - I'm capturing with the fac.println("") on both consumer and producer and have a method in the Factory class that tells it to print in JTTextArea
import java.util.Date; public class Producer implements Runnable { private Buffer<Date> buffer; private Factory fac = new Factory(); public Producer(Buffer<Date> buffer)
I am trying to write a program in Java that uses threads.Below is the program requirements:The goal of this assignment is to create a routine which creates multiple threads, has them do work in parallel, and terminates when the last thread has finished.
The Scenario: There are several groups of people in a bar watching the Olympics cheering for their country. Each group will cheer for their country some given number of times, with a random pause (between 2 and 5 seconds) between each cheer. There is enough room at the bar for up to ten different groups to sit (each would be cheering for a different country).
The Program: The task is to write a program that will simulate these cheers using threads. The program should be called cheer.X (X being the language of choice). You may use any language that supports threading. When the program is run it should ask for the number of countries and then the name and how many times it will be cheered for. The main function will then create a thread for each team and each thread is responsible for cheering the specified number of times for the correct team at the random interval. You will submit the proper source code file for me to open and compile myself, not an executable.
An example run would look something like this: How many countries are supported at the bar? 3 Enter the first: China How many cheers? 2 Enter the second: USA How many cheers? 4 Enter the third: Russia
I have printed the result of my program into an output file.
For some reason I can't figure out how to get the file output.txt to actually print.
I've tried printing it like I would normally print a file but it's not working.
Java Code:
final PrintStream console = System.out; File file = new File("output.txt"); PrintStream out = new PrintStream(new FileOutputStream(file)); System.setOut(out); System.out.println(collection.toString()); System.setOut(console);
What do I do after this? mh_sh_highlight_all('java');
I have a question: I have a Java/JSP/JavaScript project that access back end Oracle database, and provide interaction through tomcat. After we deployed our project, I found one button does not generate necessary warning message from server, but when I deployed and tested our project on local PC, it does generate correct warning message. I am using the same IE, same tomcat version, and I am sure my container is pointing to the same database, and I am sure I using same version of project code by checking with GIT.

[Code] .....
Our problem is server could not generate alignMsg. But we can get it on local deployed project.
I have written java program which can extract online data from url and i want to store it in data base in new token row in table so than i can use in my application . how could it be done using type4 drive ..
These are my code ...

I am aware that the default value of char is 0. But in this program I am getting some unexpected output
public class TestClass12{ static int[] ia = new int[1]; static char ch; public static void main(String args[]) throws Exception{ System.out.println("ch:"+ch+" ia[ch]:"+ia[ch]); } }
Output: ch: ia[ch]:0
If you see the above output ch is printed as a blank space instead of 0, while the array default value is correctly printed by taking the char default value as index. Why is ch printed as blank space?
Write a program to request a student number and their marks in 4 subjects. The program must print the student number, total marks and average mark. All outputs should be printed with suitable labels
This is the error am getting
Scanner get = new Scanner (System.in) - got a red line
int student number, total marks, average mark - got a yellow bulb with a red exclamation mark on it.
I just dont understand where the errors is where what the system dont have ... I am using netbeans ....
the below program is to read the time intervals (HH:MM) and to compare system time if the system time between your time intervals print correct time and exit else try again to repeat the same thing. By using StringToknizer class. and i have written like this
import java.io.*; import java.util.*; public class Main { static int k1,k2,v1,v2; public static void main(String args[]) throws IOException { DataInputStream o=new DataInputStream(System.in);
[Code] ....
but is showing correct for some inputs and wrong for some inputs ....
So I am trying to write the output of two different java class files to one txt file while the program runs. The file name is determined before the program is ran, through the command prompt as arguments. How can I get the second class file to edit the same txt file without running into compile errors.
For right now I'm just going to send everything that the second file outputs to a message String variable, so that the Main class outputs to the the text file. I still want to learn how to write to the same text file directly from the second class file.
import java.io.*; public class Test{ public static void main(String[] args) throws IOException{ int x; //create a new file internally called doc. But externally labelled the user input File doc = new File(args[0]); if (doc.exists()){
1.Write a JAVA program that will input 10 scores and output the Highest and Lowest score.
2.Write a JAVA program that will input the base and power and display the result: Example: Base is 4 Power is 2 the answer is 16 (Note: Math.pow( ) method is not allowed)
3.Write a JAVA program that will input an integer number, and then will output the sum of all inputted numbers. The program will stop in accepting inputs if the user entered 0.
Following is the code for my assignment where a user inputs his full name in a string from keyboard. It should be done using BufferedReader. The program will give his initials as output.
############################
For example: User inputs-> Ram Kumar Das
Program Returns-> R.K.D.
I am written the following piece of code. It does not return the correct output. If "Ram Kumar Das" is given as input, it gives R.K.K. as output. Arrays and objects are strictly not allowed.
Java Code:
import java.io.*; public class Assignment { static int i=0; static BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); public static void main (String args[]) throws IOException
So my goal is to use the graphics class to draw this shape: [URL] ....
so far I've managed to draw the bottom half, but now I want to utilize the copyArea() method to flip the bottom half and copy it to produce the upper half of the shape: [URL] ....
and this is what I wrote to produce the bottom half:
