I am trying to interact with the command line prompt and script the responses for some config. When asked if user wishes to continue I would like respond yes or no, however I would like this response to be automated without any user interaction. I am able to launch the .exe file however when the command prompt is launched I cannot get any further responses to it.
p Java Code: ublic static void runConfigure(String[] refBox1,String outDir2)
throws IOException{
String s = null;

I am just learning Java and I am have a problem running programs at the command line. I have the following code:
package java_help; import java.io.IOException; class help {
[Code].....
I can run this program in net beans were I originally wrote the program and it runs fine there. I also compile the program at the command line using javac but when I go to run this program I get a error message that it cant find main.
I'm learning about the printf command, and when I have it, it is not letting me ad an input. Here is my quick little program:
import java.util.Scanner; public class TestingPrintF { public static void main(String[] args) { // Create a Scanner Scanner input = new Scanner(System.in);
[Code] ....
The first section works good, but when i move down to the second part it just automatically finishes without letting me enter a phrase.
I am reading the excellent book Algorithms. The author of this book is using his own libraries.
I have downloaded the libraries (it is a file called stdlib.jar) and I've store it in a directory called ~/Downloads(I am using a macbook pro).
Then I have created a project with IntelliJ Idea 14.1 using the default package (as it is the only way for a program to 'see' these libraries).
The program is running inside the ide, but because of the nature of this book, all the included code must be run from the command line.
The problem is that I cannot run for example the Average class from the command line because the system asks for the external library.
Specifically the error is :
I enter : java -cp . Average
and the Error I get is :
Exception in thread "main" java.lang.NoClassDefFoundError: StdIn at Average.main(Average.java:11) Caused by: java.lang.ClassNotFoundException: StdIn at java.net.URLClassLoader$1.run(URLClassLoader.java:372)
[Code] ....
The Average class is the following :
public class Average { public static void main(String[] args) { //Average the numbers on StdIn double sum = 0.0; int cnt = 0;
I have the program written correctly, but it won't execute.
public class Welcome { public static void main(String[] args){ //Display message Welcome to Java! on the console System.out.println("Welcome to Java"); } }
I compiled the code as written below with "javac Welcome", and use the "Class" name "Welcome"
I want to read property file in java from command line argument,i.e. if i have some parameters which i have to use separately , i comment the parameters which i don't have to use that time , then uncomment when i have to use.
Is there and way to read the required parameters through command line arguments in java.
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
Now everything works in Netbeans but running it from the command line, i get an error message ".java uses unchecked and unsafe operations".I have added a bit more code to the code above
for (int i = 0; i < args.length; i++) { System.out.println("args[" + i + "]: " + args[i]); }
Just not sure how to run it from the command line,
I have a program that runs in the terminal (I use Ubuntu). It asks the user for a String, does something with it, and terminates.It works in the NetBeans terminal, but not outside of it. Specifically, regardless of what I input, it doesn't continue with the program. I enter something, press enter and it just goes to the next line in the terminal.
Java Code:
Scanner scan=new Scanner(System.in); System.out.println("Enter the music directory:"); String path=scan.nextLine(); mh_sh_highlight_all('java');
how do I pass in arguments when I run the program (still in Linux)? Is there a way to check if the program was launched from the terminal or not?
I'm facing another problem with the HFJ code which i edited some what (as given HFJ) to make it work through command line..BeatBox using command line. Getting compiled but no sound coming..
package com.BB.getPlayer; import javax.sound.midi.*; public class MiniMusicAppCmd { public static void main(String[] args) { // TODO Auto-generated method stub
I'm suddenly having trouble running classes from the command line. Previously, things were working. I cant imagine I'm doing anything differently. The sample code is below:
Code:
class HelloWorldTester{ public static void main(String[] args){ System.out.println("Hello World"); } }
Terminal output:
C:UsersmattmanDropboxProgrammingJava>javac helloWorldTest.java C:UsersmattmanDropboxProgrammingJava>java HelloWorldTester.class Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorldTester/clas s Caused by: java.lang.ClassNotFoundException: HelloWorldTester.class at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: HelloWorldTester.class. Program will exit.
What I'm supposed to do is use the time class and take the command line arguments and print them as the start and end times and then calculate the elapsed time between the two. My issue (hopefully my only as I have been working on this all day now) is that I cannot call the command line arguments using LocalTime. Below is what I have so far.
public class Clock { private LocalTime startTime; private LocalTime stopTime; //default constructor-initialize startTime to current time public Clock(){ this.startTime=LocalTime.now();
I am trying to make a method that takes in a cmd command (nslookup, systeminfo, etc), and outputs the response to a text file. I have tried a dozen different ways with no success. below is my most current failure. It succeeds when i run it, but nothing shows up in the text file.
public static void runSystemCommand(String command) { command = "ping 192.168.1.3"; try{ Process proc = Runtime.getRuntime().exec(command); InputStream in = new BufferedInputStream(proc.getInputStream()); OutputStream out = new BufferedOutputStream(new FileOutputStream("C:NetPanelDataping.txt"));
I'm having trouble with how to read a text file into my program so the words can be sorted alphabetically. Should I use something like a FileReader?
An example of what I'm trying to do is a .txt file that holds the statement "java is a simple object oriented and distributed and interpreted and robust and secure and dynamic."
The output should organize the words like so: and and and and distributed dynamic interpreted is java object oriented robust secure simple
Here's what I have:
public static void main(String[] args) { if (args.length != 1) { System.out.println("Usage: java AscendingAlphabet"
[Code].....
I can never get it to read the file correctly, it just prints the "usage: java..." statement.
I'm writing a Java program to get the gpa of a student as a command line argument. Then display the class of the degree according to some criteria. Here is my code. But it says "ArrayIndexOutOfBoundsException :0". How can I fix this?
public class Stgpa { public static void main(String[] args) { double gpa= Double.parseDouble(args[0]); if(gpa>=3.6) System.out.println("Class of the degree is: First Class Hons"); else if(3.6>gpa && gpa>=3.4)
How would I randomly assign colors and a with a name? Some functionality may require command-line arguments but I am a bit confused on how to structure this. Also, these names must appear on a color coded on a gui
The goal of this software is to provide a web interface which must be able to manage the Quagga routing daemon. For those who don't know Quagga, the only interface it provides the user is its built-in cli. My project must convert web events to commands and vice-versa. how I'm going to maintain quagga's configuration state synchronized with JSF's managed beans. The example below shows the commands one must run on quagga's cli in order to add a BGP neighbor:
In order to represent this piece of information in my project, I was thinking about mapping this to a class:
public class BGPNeighbor { private String ip_address; private Integer asn; private Boolean next_hop_self; private Boolean inbound_soft_reconfiguration; }
With this I would parse the information from Quagga's configuration and map this to classes in my software. I think it's a lot easier to do with database-based software, the problem with this project is that it's not completely database oriented. The information must be fetched from the network, parsed, converted to classes and then they would be available to JSF as managed beans. Any alteration to this classes must be converted to quagga cli commands which must be executed through the network again (telnet).
