First Java development in Eclipse

I did Java development in Eclipse. This is a memo of a sample program for beginners that only outputs Hello World. I am trying to develop SAP related, there are other than Eclipse and JDK at the time of installation, but I have recorded it in the following article.

--Installation of JDK: Building SAP system connection environment using JCo to PC that even Java beginners can do --Installation of Eclipse: JSP + Eclipse + Jetty development environment construction even for Java beginners


1. Create a project

Right-click in Project Explorer and select New-> Project. 10.CreateProject01.JPG

Select "Java Project". 10.CreateProject02.JPG

Enter the item "Project name" and finish. 10.CreateProject03.JPG

Change to Java Perspective (Eclipse screen display setting). 10.CreateProject04.JPG

2. Package and Java programming

Right click on the "src" folder and select New-> Class. 20.CreatePackage01.JPG

Enter the package name and class name and finish. 20.CreatePackage02.JPG

Save with the following source code.

package test00;

public class HelloWorld {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		System.out.println("Hello, world");




If you run it from the menu Run-> Run, Hello World will be displayed on the console. 30.RunResult01.JPG
