Java 既野一問~!!

You can use free IDE's such as NetBeans , or JCreator .

An IDE has a user-friendly screen that includes most user functions to edit, compile, execute and debug your programs. Many of them also include rather elaborate setups and configurations that help the user to organize class files.

The choice of IDE depends on your usage, and willingness to invest time to learn how to use. Most IDE's have been setup to do the simplest jobs, so not much learning is required. However, it has been recognized that NetBeans takes more system resources than JCreator, which already does a reasonable job, especially for beginners.

If you are an occasional user, such as taking a course in Java, you do not have to use the IDE's to compile and edit java programs. Many editors provide built in facilities for one-touch compile and execution, for example, in Textpad , F1 compiles, and F2 for execution of application files, F3 for executing applets. Note however, that although many people use TextPad in the try-out mode indefinitely, the user is expected to pay for the product after the trial period.
