Java Code - Multiple Execution Of Jar File With Different Inputs
Jan 4, 2014
I would like to ask you how can i execute the next code without errors.
I am trying to execute a jar (myFile.jar) file multiple times with different inputs from another jar file. More simple i have game with many players and i create a Round Robin scheduling for the tournament, i need to execute all the mach's of a round together.
When i run the next code it execute on the first game with the first players multiple times.
Java Code:
public class RunJARFile {
//10 player
//5 game per round
public static void main(String[] args) throws IOException {
for (int Tour = 0; Tour < 9 ; Tour++) {
for (int Game = 0; Game < 5; Game++) {
I am not all secure on the execution of the fileupload Primefaces.
The uploading execution occurs normally, but I would like to have a counter that control's the received files. The problem is that sending files go by so fast by this method that appears to be running in parallel. My question is whether this behavior is normal while sending files.
If it is not, where may be the error. If it is normal what can i do to make the counter really take the right value?
I'm using the scope of the "bean" type of view, but when im trying to run the session the problem also occurs depending on the file size.
If my files are very small, the execution is very fast and I cant follow the counter. If I clean the code the execution usually occurs no matter the size of the files.
@ManagedBean (Name = "bean") @ViewScoped public class BeanUpload { private int counter; @PostConstruct public void init () { counter = 0;
[Code] .....
The result on the console for 3 files is:
COUNTER EX: 1 COUNTER EX: 1 COUNTER EX: 1
If I run the code in debug mode on the console this is the result:
My code runs and compiles just fine when I insert 3 values, however, if I add anymore values NOTHING happens. When I hit the compile button, my mouse pointer turns into that loading circle thing and after 3 seconds it disappears and nothing happens. No error or anything in the console, just BLANK. This problem occurs on line 12 in my main method, and my insert method is on line 41 in the third class..Here is my main method
public class TestAVLTree { public static void main(String[] args) { /*test at least 2 diff data types*/ //AVL of ints AVLTree<Integer> avlInt = new AVLTree<Integer>(); avlInt.insert(100); avlInt.insert(50); avlInt.insert(200); //avlInt.insert(3); fails here. could it be my insert method? //avlInt.insert(17);
i am currently making a game in java and currently i am working on the basic mechanics. most of it is working fine but i cannot seem to make it so when the user presses and movment key and space to fire a bullet the bullet fires in the direction they are moving. here is the code i have for movement.
public void keyPressed(KeyEvent e) { // TODO Auto-generated method stub int bulletx = Player.x + 100; int bullety = Player.y + 20; int key = e.getKeyCode(); if( key == e.VK_W){ p.moveUp(); } if(key == e.VK_S){ p.moveDown();
I'm writing a program that accepts three doubles from the user, and performs calculations on them. I want to be able to handle input mismatch exceptions on each individually (i.e., if the user enters a double for the first, then a letter for the second, I'd like to be able to keep the value entered for the first, and only require that the user try again with the second, then the third, etc.)... I tried putting each input instance into its own try/catch blocks, but it always goes back to #1 when an invalid input is entered. Right now, I have all three in one try/catch:
So I'm learning java having been using c#. I based this code off an example from class. It compiles fine with no errors, but I'm getting this:
Which model do you want? + Standard,Electrum,CurveHilted, or Tonfa Standard Exception in thread "main" java.lang.ClassNotFoundException: Standard at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method)
I need to generate a league table in Java based on results provided in the shape of user input. I have the 6 teams in an array. I need to ask the user how many wins, draws, losses each team has had.
for (String element : teams) { System.out.println( "Please enter the number of wins, draws and losses for " + element); int[] wins = new int [6]; int[] draws = new int [6]; int[] losses = new int [6]; }
How do I pull 3 separate values from the user and then store each value in a separate element of each array? so if one team wins 3, draws 2 and loses 1 - I need to put 3 into the wins array, 2 into the draws array and 1 into the losses array? I then need to total all this in a table.
The first line is the number of test cases and the second line is the corresponding values for the test cases. Java code for taking multiple inputs in the single line separated by a space.
I have got 2 classes in a source file, 1 real class and 1 test class with main() method. While executing with java command which class name should i write - real class or test class???
I am new in java. I executed a java program using eclipse. the program contain two java file. when i try to run it using terminal in Ubuntu. Two files are not linking. it shows error. i am attaching all the data.
It shows the following error
regex2string.java:83: error: cannot find symbol str = randomstr.nextString(2000); ^ symbol: variable randomstr location: class regex2string 1 error
I've got a very simple java program (J.java, see below) on my application server that successfully connects to an Oracle 11.2 database on a database server (both servers are Linux CentOS) using JDBC thin driver from Oracle.
As you can see from the setURL command in the Java code below, I've configured the application and database servers to sit next to each other, and they're on the same network (cross-cable connected to each other), so there's no network traffic on these (development) boxes except my code.
The problem is the execution time varies a lot. If I run it 5 times, it (seemingly randomly) could take 0.01 seconds, or 10 seconds, or 50 seconds, or over a minute to execute. If it takes over a minute (roughly), the program doesn't complete, but the error shown below is returned instead.
------error returned when execution take more than about 1 minute------- gf@host9 [~/dbwork]# java -cp ./ojdbc6_g.jar:. J Exception in thread "main" java.sql.SQLRecoverableException: IO Error: Connection reset at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:494) at oracle.jdbc.driver.PhysicalConnection.<init>(PhysicalConnection.java:547)
I have a EAR file which has a java class file and EAR file is deployed in weblogic.I have to call the java class of EAR file from a standalone java code which is present inside a JAR.While making the call to EAR i have to pass a parameter from JAR to one of the methods of class file which is present in EAR.
I tried working with XML today, since that's what my book teaches. First, I read some data about Product objects that are suppose to represent products with a code, description, and price. That worked fine. Then, I tried creating a writeProducts(ArrayList<Product> products) method, and man it did not go well.
How it works is that there is an ArrayList instance variable in the class that keeps track of all of my products after the readProducts method returns that ArrayList from the XML file. When I ran the method I had a lot of stack traces printed. I then checked the file on a web browser and an editor, and saw it was completely empty. Here's the code:
import java.util.ArrayList; import java.io.*; import javax.xml.stream.*; // StAX API public class XMLTesterApp { private static String productsFilename = "products.xml"; public static void main(String[] args) { System.out.println("Products list:");
how to set the columnwidth in csv file using javacode.
I used FileWriter class to upload data into the csv file but csv file is taking default width while showing content. Is there a way to set the fixed column width or set width dinamically based on value?
This is a program to input a sentence and print the words that start with a vowel.......There is no syntax error but on executing and typing the sentence and pressing enter,I get a error saying :
java.lang.StringIndexOutOfBoundsException: String index out of range: 0 at java.lang.String.charAt(String.java:658) at sentence.main(sentence.java:22)
I am having an issue with using FileWriter to print some text to a text file. In the following code, I am supposed to be able to print the initial attributes and the user changed inputs into a file but all I am getting is the memory locations of the objects I created in one long line.
package project3final; import java.io.*; import java.util.*; public class Project3Final { static class Instrument { char [] stringNames = {'E', 'A', 'D', 'G', 'B', 'E'}; private final String instrumentName;
I am trying to complete this question. I understand the most of it but I haven't go a clue to read in the file name.
Full question: Implement a program that reads in a Java source code file and checks to see if it has balanced {}brackets. Your program should use a stack, implemented as a linked list, to check the brackets.
NOTE: you can use a reference called top which points to the head of the list. Your program should run as a command line program and should take a filename as an argument and print one of BALANCED or NOT BALANCED.
For example: c:> java checkBalanced "myProgram.java" BALANCED
There is method in the class of my application and there are four other class which is running in different machine means different jvm and these classes are accessing the method of my class. then how to protect my method from accessing other class at the same time. I am not able to use synchronized keyword because this works only for single jvm.
I am trying to write a program for converting positive binary inputs into hex. in the hex output the point (".")is missing.
Suppose my expected output is e7.6 , but i am getting e76
only the "." is missing.
here is my BinToHex class..
import java.io.*; public class BinToHex { double tempDec,fractionpart; long longofintpart,templongDec; String input ="11100111.011"; String hexOutput=null,tempDecString,hex = null; static int i = 1;
i want to write a class in such a way that i should get the current execution time of another class which is running. I searched in net but it shows only how to calculate the time duration of the current class which is running. But as per my way, i need the execution time of one class from another class. How to do this ?
Write a java program that will ask a user to input grades until the user inputs the sentinel value -1. The program should test each input to determine whether 0<=grade<=100. If the grade entered is within this range, the program should print "Grade accepted;" if not, the program should print "Invalid input".
public class StringTest { public static void main(String args[]) { String s1="hello"; s1=s1.concat("me"); String s2="hellome"; if(s1==s2) System.out.println("s1 and s2 has same referance"); if(s1.equals(s2)) System.out.println("s1 and s2 has same content"); } }
Output is : s1 and s2 has same content
if after concatenation both string is stored in string pool it will refer to same memory location and other confusion is after any string operation like (concatenation , replace , substring) jvm creates a new string in which memory area..?? Heap or String pool.
