Java Forum / General / April 2008Java IDE for Beginners
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. > 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 [quoted text clipped - 3 lines] > faulty, or somethin is wrong with my sys config. so, can anyone > recommend an IDE for me? 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?

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/third_edition/html/j3TOC.html The Really Big Index (A list of all content pages in the The Java Tutorial) http://java.sun.com/docs/books/tutorial/reallybigindex.html Java Platform, Standard Edition 6 API Specification http://java.sun.com/javase/6/docs/api The Java Developers Almanac http://www.exampledepot.com SignatureThanks in Advance... http://ichbinquotations.awardspace.com IchBin, Pocono Lake, Pa, USA http://ichbin.9999mb.com ______________________________________________________________________ 'If there is one, Knowledge is the "Fountain of Youth"' -William E.

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? - Lew I don't knowif the newest version of that book has changed but Ivor recommends Jcreator as I had earlier. ;) The book does have errors as does any programming book. Even if you copy it word for word make sure you check the errata page for the book to see if they've made a mistake and list the correct code. > i tried this exact same code on eclipse IDE (besides, netbeans is far > better than eclipse, especially for beginners like me coz it gives [quoted text clipped - 7 lines] > besides, does JRE has anything to do with netbeans, i have JRE 5 > installed. but i have JDK 6. spammer -> enquiries@optimaloptimization.com >> Scratch Last code, this is the correct code. >> [quoted text clipped - 41 lines] > The Java Developers Almanac > http://www.exampledepot.com 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'm a little rusty in Java, but the following should meet your purpose. public class VariableArgumentList { // Creates a new instance of VariableArgumentList VariableArgumentList() { private String[] arguments = { "2", "two", "4", "Four" }; // add more args to print out if you want } public static void main( String[] args ) { for ( i = 0; i < arguments.length(); i++ ) { System.out.println( arguments[i] + "\n" ); } } } > public class VariableArgumentList > { [quoted text clipped - 13 lines] > } > } This doesn't help resolve the OP's issues with getting variable argument lists to work, that is, the language construct where you declare a method as <access-specifier> <return-type> Foo( T ... args ); Also, your example as posted won't compile. There is no declaration of the variable 'arguments' in the main method. There is no declaration of the variable 'arguments' as an instance variable. The 'private' access specifier inside the constructor won't work. The index variable i in the for() loop is not declared. Array length is found by the array instance variable 'length', not a method 'length()'. - Lew I perfer eclipse, but I have to use netbeans at work, so I'm familiar with both. In projects I've worked on eclipse is better (for me) - it works faster, builds faster, does refactoring better, shows warnings, offers better quick-fix solutions, has smarter code assist and I like cvs support better. However, netbeans has (except warnings) all that features too (only not as nice), and has far superior gui designer. People new to java usally like netbeans more, for no particular reason. I would suggest eclipse to a beginner because it shows lots of useful warnings that will teach you to write nicer code. > 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 [quoted text clipped - 3 lines] > faulty, or somethin is wrong with my sys config. so, can anyone > recommend an IDE for me? > I perfer eclipse, but I have to use netbeans at work, so I'm familiar with > both. [quoted text clipped - 18 lines] >> faulty, or somethin is wrong with my sys config. so, can anyone >> recommend an IDE for me? IMHO - I disagree. For a beginner in the Java Language, IF new to programming, to use straight Java, Javac and a text editor. Using a professional IDE for Java at this point would be very confusing. They need to get the Java fundamentals down first. If you have programming experience with other languages and IDE's then no problem with Eclipse, Netbeans or Sun's Sun Java Studio. I guess if the OP does not care about complexity. I guess my comments maybe mute.

How I hated java case sensitivity when I swithced from MS Basic back then ;) However JD specifically asked about an IDE so I shared my experiences with IDEs I tried. >> IMHO - I disagree.

Taylor, Regular Guy (1952-) Using an IDE can be dangerous if you don't learn a language properly. Having said that I don't believe in the whole "use notepad to learn" theory. I would suggest using JCreator LE http://www.jcreator.com/ It's the free version, it loads fast and it won't be as confusing as Eclipse or Netbeans to a newcomer. I know you said you don't care if something is complicated but if you want to learn properly you can't start off worrying about all the aspects of the IDE. You need to focus on the language only. > 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 [quoted text clipped - 3 lines] > faulty, or somethin is wrong with my sys config. so, can anyone > recommend an IDE for me? spammer -> enquiries@optimaloptimization.com Free MagazinesGet these publications absolutely FREE for up to 12 months.
