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!”);
I just went over how to open and edit text files in java. Was wondering how to open mp3, mp4 and other media files, is there a special package i need to import or plugin that I need to install in eclipse?
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"
There is no error shown in the code. but, when i run my program for start, the page before cannot proceed and yet, i cannot proceed to this page and the application stop unexpectedly. below is the error that i gain in logcat.

I want to execute my jsp code to compare two dates after every 10 seconds if user enter date and current sys date are equal it will send the mail to the user automatically. Below is my jsp code
this if condition i want to check the date after every 10 seconds and when two dates are equal it will send the mail using below mail code
if(ExpcReDt.compareTo(dateStr)>0) { out.println("Expected return date is greater than current date"); } else if(ExpcReDt.compareTo(dateStr)==0)
I am unable to run this java mail code, whats the error!!
public class Class1 { final String senderEmailID = "from@gmail.com"; final String senderPassword = "password"; final String emailSMTPserver = "smtp.gmail.com"; final String emailServerPort = "465"; String receiverEmailID = null;
[Code] ...
I get an error as this
javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465, response: -1 at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1949) at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:654) at javax.mail.Service.connect(Service.java:317)
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?
The program below compiles and functions correctly for the most part. It is supposed to be a simple GUI Text Editor with Edit and Format functions. The content pane is supposed to be a scroll pane, however no matter how much I type into the editor, the scroll bar does not appear. Also, the none of the functions under the "Edit" menu work.
I am having an issue where the code does something very strange when run. Everything seems to be ok in the code but I don't know what is wrong as no error is given.
Here is the code:
import java.util.Scanner; public class Pizza { private static int pizzaSmall = 10; private static int pizzaMedium = 12; private static int pizzaLarge = 14; private static int costPerTopping = 2; /**@return The total cost of the pizza when given the pizza size and the toppings.*/
[Code] ....
And here is the console output:
Please enter the number of Cheese toppings that you would like: 1 Please enter the number of Pepperoni toppings that you would like: 1 Please enter the number of Ham toppings that you would like: 1 Please enter Small for a Small Pizza, Medium for a Meddium Pizza, and Large for a Large Pizza: The number of Cheese toppings is 1. The number of Pepperoni toppings is 1. The number of Ham toppings is 1.
I am running my Java code with SecurityManager enabled. The code must load a DLL and invoke methods written in C using JNI. Is there a documentation available describing the permissions needed for native code?

Why can't I see the text when I compile the java code?
Java Code:
import java.io.*; import java.util.logging.Level; import java.util.logging.Logger; import javax.imageio.ImageIO; import javax.swing.*; public class WorldTravel { public static void main (String[] args){ JFrame f = new JFrame("World Travel!"); BG_text p = new BG_text();
I have a major problem. the text size is like 6 or 8 pt font and I can't read it. I'm trying to run a downloaded exe program which uses the jre7 which I had to download beforehand. the font size stays at 6 or 8 even if I try to change it in windows settings. it's a high res monitor on a lenovo yoga laptop. is there a way for me to edit the java code and manually change the font size?
I want to write a little java program that when ran it will add information to my host file. A screen will pop up with a button on it. When you click the button it will add a few ip to domain connections. In order to edit the host file with notepad you must first give notepad admin privileges. I can't find a way to do this and I'm extremely fresh to programming. Is there a way I can write directly to the file or is there a way to run notepad with elevated privileges?

I'm trying to make the program read the "Entity.sql" File and then execute it to make it run in phpmyadmin. I did used a mysql connector to link netbeans to mysql and then it should used the Connection for phpmyadmin to execute the Statement (Entity.sql).The Entity.sql file contains as sql Statement:
CREATE DATABASE IF NOT EXISTS Student
The problem is that it's not working and it's giving me this error:
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

My java class doesn't execute a shell sript, I had given the java io file permission read and execute over the script shell to the user who execute the java class, also I executed the script shell in the console each RAC server using oracle user session and the srcript shell works. My team DBA told me that " The user server process is oracle". My script shell resides in all RAC server file system the last result looks as follows:
/home/mydir/dir2/mybin/compacta_archivo.sh No Funcionando!! java.io.IOException: /home/gi91591/reppostpago/bin/compacta_archivo.sh not found
[Code]....
of course, the script file exist on my file system, it has the suitable permission as the test result i got each time I executed on the console. My Oracle version is 11.2.0.3.0 on Rac ASM.

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.
What's wrong with my Java program? When I open it using appletviewer, the applet opens but stays blank and an error message appears in Terminal.
Java Code:

[Code] ....
Error Message:

If there are 4 values in underlyingTickersList A, B C, D and E ... I am getting those values correctly displayed in each text field.
However if I submit the form with all these value how can I get it in the bean? I guess I need to have dynamic id or name for each text field. How can generate it?
Note** I dont have Struts framework.. I am using request.getParameter to fetch the values and set into the bean variable.
