Java IDE for Beginners

[JD]

hi, i m new to java, i want to know if there is a good and free Java IDE
that i can use that'll help me, i dont care if its complicated , i just
want it to be good, i tried netbeans which comes bundled with java sdk 6
from sun, the prob with it is that , if i use for-each loop, it says to
use option -source 1.5, i used it, didnt work, so either the IDE is
faulty, or somethin is wrong with my sys config. so, can anyone
recommend an IDE for me?

You can try Eclipse. Its quites powerfull and you can download alot of
plugins to it for free.

Well the other popular free IDE is Eclipse: http://www.eclipse.org

If I was just starting out with Java I would not user Netbeans nor
Eclipse. You will spend a lot of time figuring out the IDE and its
functionality and not the Java language.

I would start with an IDE called 'BlueJ' http://www.bluej.org
It is a simpler interface and it will teach you how to program Java with
an OOD\OOP approach.

They also have worked with the Netbeans development people and have just
release a BlueJ-Netbeans version.

Or you made a mistake, which is by far the most likely. I use Netbeans and
have not received such a message.

Why don't you post the construct that is failing? (Copy-and-paste it; do not
paraphrase.)

public class VariableArgumen tList {
for(int a,a<=10;a++);

/** Creates a new instance of VariableArgumen tList */
public static void main(String[] args) {
printAll(2,"two ",4,"Four",4.5, "Four Point Five");
printAll();
printAll(25,"An ything Goes",4E4,false );
}
public static void printAll(Object ... args){ // Error Here
for(Object a:args){ // Error Here
System.out.prin tln(a);

}
}

}
here's the class. it wants to use -source 1.5 option, i gave it, but
still nothing, i already did a clean install of the setup bout 5 times
now, still it persists.

Scratch Last code, this is the correct code.

public class VariableArgumen tList {
// Removed faulty code from here.
/** Creates a new instance of VariableArgumen tList */
public static void main(String[] args) {
printAll(2,"two ",4,"Four",4.5, "Four Point Five");
printAll();
printAll(25,"An ything Goes",4E4,false );
}
public static void printAll(Object ... args){ // Error Here
for(Object a:args){ // Error Here
System.out.prin tln(a);

}
}

}

A method can not have a parm list the way you have it defined.
Could do it this way:

public static void printAll(int v1, String v2, int v3 String v4, float
v5,String v6 ){

Or create an arraylist with the stuff you want to print and then pass that.

for(Object a:args){ // Error Here
System.out.prin tln(a);

}
}

}

Your code is completely wrong.

You need to look at the Java documentation for calling and passing data
to a method.

You need to be reading up on Java in of these places:

The Java Language Specification, Third Edition
http://java.sun.com/docs/books/jls/t...tml/j3TOC.html

The Really Big Index (A list of all content pages in the The Java Tutorial)

i tried this exact same code on eclipse IDE (besides, netbeans is far
better than eclipse, especially for beginners like me coz it gives
popups with explaination of methods) and it works, i tried this exact
code using javac.exe , it works, i m using the book form WROX called
ivor horton's beginning java sdk 5. the for-each loop and the new
parameter passing was introduced in jdk 5, i can do it another way, but
i wanna try this way to learn it, i like netbeans, but it looks like
that i really have no choice but to go for eclipse.

besides, does JRE has anything to do with netbeans, i have JRE 5
installed. but i have JDK 6.

Very sorry.. I should have tested the code. I have never seen a method
have an argument list like this.. Guess I should read those docs.

I use Netbeans 5.5 with JDK 6 and it accepts these constructs just fine. But
you must hook your project up to a JDK, not a JRE.

From the Netbeans menu: "Tools / Java Platform Manager".

What are the exact error messages you get?
