Hello, World in Java on Mac OS X
This documents instructs you on how to setup a Java programmingenvironment for your Mac OS X computer and provides a step-by-stepguide to creating, compiling, and executing a Java program.We assume you are running at least OS X 10.2.3.All of the software is freely available on the Web.
- Open a terminal window. You can find this underGo -> Applications -> Utilities. Drag the Terminal to your dock sinceyou will be using it frequently.
- You should now have a Terminal window somewhere on the screen.It will have a command prompt that looks something like:
- To check that you have the right version of Java installed, typethe text in boldface below.
If Java is installed, you should see something like:
Now, check that the Java compiler is accessible.
If it is installed, you should see something like
If not, install the Developers Tools CD that came with your Mac anduse Software Update to make sure you have the latest version.
- Now, create a directory to store your Java programs.In the window containing the Command Prompt, type the bold commandsbelow:
The mkdir command creates a new directory;the cd command changes the current working directory.After executing these commands, your working directoryis the newly created ~username/introcs/hello/. All of yourfiles for Assignment 0 will go here.Don't be scared by the Terminal - you will only need to use afew basic commands. Keep this window open since you will need it laterin the assignment.
- Since you will be using the Terminal frequently, we recommend customizingWe recommend customizing the default settings.
- To check that you have the right version of Java installed, typethe text in boldface below.
- Downloadthe latest stable version of JEdit using the MacOSX package link.
- We recommend the following JEdit customizations.
- Enable Mac OS style menubar inUtilities -> Global Options -> Plugins -> Mac OS Settings
- Change the default indentation to four spaces viaUtilities -> Global Options -> Editing -> Indent Width andUtilities -> Global Options -> Editing -> Tab Width. Global Options -> Editing -> Soft tabs.-->
- Change the default tab width when printing to four spaces viaUtilities -> Global Options -> Printing -> Tab width when printing
- Add line numbers by checking Utilities -> Global Options -> Gutter -> Line Numbering
- Allow at most 80 characters per line byUtilities -> Global Options -> Editing -> Word wrap -> hard andUtilities -> Global Options -> Editing -> Wrap margin -> 80.
- Change the default line separator to Unix viaUtilities -> Global Options -> Loading & Saving -> Default Line Separator
- Remove the annoying . that marks the end of a line by uncheckingUtilities -> Global Options -> Text Area -> End of Line Markers
- To associate .java files with JEdit so that when you double-click a .java file,it opens it in JEdit:
- Right click a .java file (or click then shift-right click it if using Windows NT)
- Choose Open With.
- Select JEdit from the list of programs or locate JEdit by selecting Otherif necessary.
- Check the Always use this program to open this file type box

- Launch JEdit Start -> jEdit.
- In the JEdit window, type the Java program exactly as it appears below.If you omit even a semicolon, the program won't work.
- When you're done, save the program usingFile -> Save As, chose the directory C:introcshelloand type in the file name HelloWorld.java.The file name is case sensitive and must exactly match the name of the classin the Java program. Don't forget to include the .java extension in thefile name.
- From the Command Prompt, type
If javac complains in some way, you mistyped something, and you should check your program carefully. Ask for help if you can't see the mistake.
- If everything went well, you should see the followingin the Command Prompt:
Silence is golden in computer science.
- If everything went well, you should see the followingin the Command Prompt:
- At the Command Prompt, type
- If all goes well, you should see
- You may need to repeat this edit-compile-execute cycle a few times before it all goes smoothly.Use the up and down arrow keys to repeat previous commands and avoid extra typing.

If you use Java for programming, read on to learn about tools like Eclipse IDE, the Java Development Kit, and other must-know tools.
If you are a web developer, it is a no-brainer that much of your professional life will be spent using Java. This is one commercial grade programming language, you just can’t avoid.
There are two schools of thoughts about Java; there is one that says Java is one of the simplest and more powerful programming languages going around and at the other end of the spectrum are people who say it is a language hard to use and is quite intricate.
Whatever the school of thought you subscribe to, there is absolutely no doubt that you’ve got to get your Java coding right. DZone has a comprehensive list of common Java mistakes that developers usually end up making. One of the ways of ensuring you write richer and bug-free Java code is by using the many tools that are at your disposal. Each of these tools addresses different developer concerns, but there is one common theme running through them and that is – they offer excellent support for coding and development.
A word of caution here – One of the many myths surrounding Java programming is that the availability of comprehensive IDEs and tools means you can afford not to have a comprehensive understanding of Java. But that’s not how it works. These tools make life simpler for you, only if you know your way around Java.

Now, let’s take a look at 15 such tools:

1.JDK ( Java Development Kit)
I know what you are going to say, “of course you need a JDK to get started with Java”; but the fact is there is nothing obvious in programming. If you plan on developing Java-based applets and applications, your first need to get yourself a tool like JDK, which includes the necessary Java Compiler, the Java Runtime Environment, and the Java APIs. It will help you get started with Java.
2.Eclipse IDE
Ask experienced Java developers about their favorite Java Integrated Development Environment (IDE) and quite a number of them will point to Eclipse. Eclipse provides much-needed assistance for code completion, refactoring and syntax checking. It also offers something called the Java Development Tools project (JDT) that provides a range of tool plugin-ins to help develop all kinds of Java applications.
