API To Invoke Terminal In Ubuntu
Jun 5, 2014
I am trying to build and IDE for NASM in Java for Ubuntu. There are other IDE's for NASM but they are in C or C++. So i thought i should try making one in Java. Well I am done with the GUI part.
How should i link the NASM compiler to the IDE.
Or
There is another way like "DEV C++ IDE" does in Windows is that it invokes the CMD and runs it in that so i could try doing something like that by invoking the TERMINAL in Ubuntu and running it in that. Does java have an API for this purpose.

I have developed a Java GUI by using Netbean. The user interface will get the user parameters that are needed by a c++ program (which I also developed). Upon clicking the run button java will execute the c++ program with the inserted parameters by launching and X-term session (using Runtime.getRuntime().exec(command) ) . Everything works fine in this way. However I do not find very elegant to launch an external terminal to run the C++ code. Is it possibile to have a terminal that is integrated within the java GUI? And run the C++ code within it?
Moreover, since the C++ code may take several hours to finish the job is there a way to read its output and use it in order to make, for example, proceed a progress bar?

So when writing my first "Hello World" app everything seemed to work just fine. I wrote the code, compiled it, and then ran the class file and it worked, I got the return Hello World! But when I tried to write another app which is basically the exact same thing just a different sentence, I keep getting a bunch of error codes saying illegal character. I did everything the exact same. I am using Text Edit on a Mac and using Terminal to execute the Java code.
Here is what I wrote....
public class MyFirstApp
{
public static void main( String[] args )
{
System.out.println(“i rule the world!”);
[code]...

I used Ubuntu 13.10 on a Chromebook and Java7 and Java8 both worked nicely. Not on Ubuntu14.04, however.
I can try
sudo apt-get install openjdk-7-jdk
javac -version
java -version
… and it tells me 1.7.0_51 IcedTea etc. I haven't found an OpenJDK version of Java8, so I tried the usual technique of unzipping the Oracle download into /usr/java (which I have created and given “campbell” ownership of).
campbell@xxxxx:~$ /usr/java/jdk1.8.0_05/bin/java -version
bash: /usr/java/jdk1.8.0_05/bin/java: cannot execute binary file: Exec format error
campbell@xxxxx:~$ /usr/java/jdk1.7.0_55/bin/java -version
bash: /usr/java/jdk1.7.0_55/bin/java: No such file or directory
Same download in my home directory as I had last week. I repeated the download and got the same error. It is different from the error for Oracle Java7, which I haven't actually got installed at the moment.
I shall probably revert to Ubuntu13.10 for a bit.

I have built a Java app that uses SQLite (sqlite-jdbc-3.8.7.jar). Running the jar file on windows works as expected however, trying to run it on Ubuntu Server 14.04 has turned into quite a task!
I put together a brand new machine in VirtualBox for testing. I installed Java (sudo apt-get install default-jre) and have installed SQLite (sudo apt-get install cl-sql-sqlite3 sqlitebrowser). I created a new sub-directory within my home directory and copied over the jar file. From terminal, I then run the command: sudo java -jar ProductionView.jar and I receive a java.lang.unsatisfiedlinkerror. For troubleshooting, within the app, before making a connection to the db, I have printed out the location of where the db is to be created and it is correct (see attached pic). Is there more that needs to be configured before I can run this app on Ubuntu? I have posted the relevant code below :
(AppDatabasePath() is what is printed in the image...).
public static String AppDatabasePath() {
return AppPath() + APP_NAME + ".db";
}
public static String AppDatabase() {
return "jdbc:sqlite:" + AppDatabasePath();

I am trying to run tshark command using runtime environment in java on ubuntu . My code is as follows :-
try {
String destip = map1.get((String) innObj.get("value"));
Runtime run = Runtime.getRuntime();
String tshk = "/usr/bin/tshark -r /home/pratibha/Desktop/vox.pcap -Y "ip.dst == "
+ destip
+ " && http" -T fields -e tcp.port -e col.Info";
Process pr = run.exec(tshk);
[code]....
map1 is hashmap which contains the destination ip adress.When i run the above code the exit code for process (pr) is 1 and hence the tshark command is not executing properly.

From java running on Windows, I need to access a file on a remote Ubuntu machine. I use the following:
URL U = new URL ( "http://" + SERVER_IP + ":" + SERVER_PORT + "/" + ClsName + ".class" );
where:
SERVER_IP is the Ubuntu IP address obtained from any site that shows the IP address of the machine you are using.SERVER_PORT is the Ubuntu port where the server is listening.
Now:
Do I need to modify this code any further?Do I need to configure the Windows and/or Ubuntu machine(s) for this to work?

I'm pretty new to Java. I was working the project about gamble. I'm having trouble with invoking the void method from another class. This is what I have done so far.
There are two classes, and I'm trying to invoke gambleAnotherRound method from gambler class into highlighted part in casino class. So, what I want to do is when the program generates "else" part, it goes back into another gamble round.
public class gambler {
public void gambleAnotherRound(double dollarsBet) {
dollarsSpent += dollarsBet;
Random randomNumbers = new Random();
double randomDouble = randomNumbers.nextDouble();
[Code] ....
Below one is casino class.
// use a System.out.print statement to ask how much money each gambler should bet.
// Then declare a variable dollarsBet of type double, and set its value to the keyboard's
// keystroke (be sure to use keyboard.nextDouble()).
// If the user enters 0, then issue a break statement, so that the while loop terminates
// Else, invoke the gambleAnotherRound method of each Gambler, and pass it the variable dollarsBet
[code] ....

this is the problem Write a Java project with two different classes. First class named Lab11main should contain only the main() method and the second class named Lab11 should contain a method named int[] reverseArray(int array)which will receive an array from main() method in Lab11main class and then reverse the whole array and should return the reversed array to the main() to print out.
this is what I did
my main class
Java Code:
package java4;
import java.util.Scanner;
public class Lab11main {
public static void main(String[] args){

I had to write a class called Thermometer, that has one instance variable (an integer) for the temperature in Fahrenheit. I had to include the following methods
-a constructor that initializes the temperature to 60
-there is a method to change the temperature
-there is a method to display the temperature
-there is a method to reset the teperature to 60
Here is the code for that.
public class Thermometer {
private int temp;
private int thermometer;
public Thermometer() {
thermometer = 60;
[code]....
Now I get to the issue. I have to write a test class called thermometer to test the thermometer class. I need to test each method while displaying the temperature after it. My professor said I should use the invoke method but didn't go into much more detail than that.

2. Capture the response of the webservice and persist the data in DB.

I am trying to invoke some methods in a for loop in order to print some info stored in a List. But for some reason, compiler pops a message saying "cannot find symbol - method getEmpID(). You are using a symbol here (a name for a variable, method or class) that has not been declared in any visible scope." But I am pretty sure that method getEmpID (as also getName(), getAfm(), and payment() ) have been declared as public.
Note: My List contains objects of different type (SalariedEmployee, HourlyEmployee). I hope this is not the factor causing this problem.
Java Code:
import java.util.*;
abstract class Employee{
private String name = "";
private String afm = "";
private long EmpID;
static long count=0;

I am trying to override the equals method for my class TeamMember I have two fields:
private Details details;
private double salary;
Code for override I get an error on salary saying cannot invoke equals (double) on the primitive type (double)
Is their something I am missing/coding wrong?
Java Code:
public boolean equals(Object obj) {
//test exceptional cases
//avoid potential NullPointerException/ClassCastException
if ((obj == null) || (this.getClass() != obj.getClass()))
return false;
TeamMember other = (TeamMember) obj; //cast to a TeamMember object
// compare fields details and salary
return this.details.equals(other.details)
&& this.salary.equals(other.salary);
} mh_sh_highlight_all('java');
