How To Compare Int To A Empty String To Input Error Message To User

Apr 16, 2015

I made a guess a number program but I am having issue figuring out a way that when a user enter's in nothing for the program to spit out a message saying "hey entering nothing doesn't work try again" then ask for input. I have done some research and from what I have found is to read the input in as a String rather than int, and use something like Integer.valueOf() to get the integer value but I am completely lost on how to apply that to my program here is my code

//import statements
import java.util.*; //for scanner class
// class beginning
public class Guess {
public static void main(String[] args ) {
//Declare variables area
int guess, secretNumber = (int) (Math.random() * 10 + 1), lowGuess,highGuess;

Terminal Within Java GUI?

Sep 19, 2014

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?

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.

Using Text Edit On Mac And Using Terminal To Execute Java Code

Aug 7, 2014

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!”);
