Hi everyone,

jwenting is right. Plug in ant as its more useful and easier and to build an ide is not an easy task. But if you want to still pursue it read up about pipe streams in java. You will also have to use window listeners and not set a default closing for the JFrame.

Of course what he's doing/planning isn't really to make a compiler but to call an external compiler

As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

Maybe a bit late, but here's a new article on java.net that does what you're looking for:
http://weblogs.java.net/blog/kirillc...ction_and.html

The last part is irrelevant as it deals with some obscure XML generation from Java objects, the first part deals with dynamic compilation and classloading.

Dear Ghost,

I want to make a Java Compiler in Java.

Is it possible to create a Java compiler? Could you

make a Notepad-like application, save the code as

a .java file, compile it into a .class file, and run it?

Basically, I want to combine Notepad and Command

Prompt. I think u have that Code. Please send that

full coding please. Im waiting for ur seen reply.

Thanks in advanced for your help

I doubt he or anyone including myself will send the code.
What you can do is create a topic on creatig an ide by yourself and i'm sure the others will walk you through it if you have specific questions

Here are some tips for you
Runtime
JTextArea
Pipe And Streams

I'll help you with your program, but you need to show some effort! At least create the GUI and TRY to send commands to command prompt. Then I'll be glad to help.

Can you help me wlth the following work?:
This sample program shows how to print the current month, now using the "Calendar" object (instead of the Date object which has been deprecated, meaning it has been slated for removal from the language).

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
// Program prints the current month
 
import java.util.Calendar;
 
public class ShowToday {
static String[] monthArray = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" };
 
public static void main(String[] args) {
Calendar rightNow = Calendar.getInstance();
int month = rightNow.get( Calendar.MONTH );
// This will be a number from 0 to 11, representing January to December
System.out.println("month: " + month );
// Using the above array, this will print "Jan" thru "Dec"
System.out.println("month: " + monthArray[month] );
}
}
// Program prints the current month

import java.util.Calendar;

public class ShowToday {
static String[] monthArray = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" };

public static void main(String[] args) {
Calendar rightNow = Calendar.getInstance();
int month = rightNow.get( Calendar.MONTH );
// This will be a number from 0 to 11, representing January to December
System.out.println("month: " + month );
// Using the above array, this will print "Jan" thru "Dec"
System.out.println("month: " + monthArray[month] );
}
}
