To make a program and execute it, development environment and runtime environment are necessary.
We need a software to write Java programs and another software to compile Java programs converting them to intermediate codes.
These softwares are called development environment.
We also need a software called runtime environment to execute the intermediate codes that are compiled.
In addition to development environment and runtime environment, we will use an Integrated development environment (IDE) , ‘ecliplse’.
‘eclipse’ has many functions that make us to develop Java system efficiently. Therefore, when we develop a system with Java, it is better to set up eclipse with JDK which is Java development and runtime environment.
Here, we will introduce you to some necessary procedures to construct Java environment for Windows and Mac.
