If You Are Using an IDE:

Because there are many Java IDEs, we cannot include specific instructions for all of these.  The following are general steps that should apply to most of them. You will need to consult your IDE’s documentation for specific instructions.

1. Start your Java IDE and perform any necessary setup operations, such as starting a new project and creating a new Java source file.

 2. Use the IDE’s text editor to type the source code exactly as it is shown. Be sure to place all the punctuation characters and be careful to match the case of the letters as they are shown. Save it to a file named MyFirstProgram.java.

3. After saving the program, use your IDE’s command to compile the program. If you typed the contents of the file exactly as shown, you shouldn’t have any syntax errors. If you see error messages, compare your code to that shown. Correct any mistakes you have made, save the file, and run the compiler again. If you see no error messages, the file was successfully compiled. Use your IDE’s command to run the program. You should see the message “Hello World!” displayed.
