Hello World in Java (Mac OS X) Hello World in Java (Mac OS X) This document instructs you on how to set up a Java programming environment for your Mac OS X computer. It also provides a step-by-step guide for creating and compiling a Java program in IntelliJ and executing it from the command line. You will need a Mac running Mac OS X 10.8 (Mountain Lion) to Mac OS X 10.13 (High Sierra). Install the Java Programming Environment The installer installs and configures a Java programming environment, including OpenJDK 10 and IntelliJ IDEA, Community Edition 2018.2. • Log in to the user account in which you will be programming. Your account must have Administrator privileges.

• Download the Mac OS X installer. • Double-click lift-java.pkg to install the software. Enter your Mac OS X password when prompted and use all of the default options.

Warning If you have previously used IntelliJ 2018.2, run this installer only if you want a clean re-install. The installer overwrites any previous IntelliJ 2018.2 settings with our novice-friendly settings.

IntelliJ organizes Java programs into projects. In our context, each project corresponds to one programming assignment. A typical project contains Java programs, associated data files, and course-specific settings (such as compiler options and style rules). • Download the project for your programming assignment to a convenient location (such as the Desktop).

[ COS 126 assignments ] • [ COS 226 assignments ] • [ Coursera Algorithms, Part I ] • Double click the zip file to unzip.

Then, you should see an assignment logo (in the main editor window) and a list of project files (in the Project View sidebar at left). Tip Use the Tools menu to compile and execute your program from IntelliJ. The Build and Run menus support additional options (such as a debugger) for advanced programmers. Also be sure that the main editor window is active before using the Tools menu (e.g., by clicking the code you want to compile or execute). Compile and Execute the Program (from the command line) The command line is a simple and powerful mechanism for controlling your programs.
