Simple and practical Java eclipse

1. The simple use of eclipse

Steps to use for eclipse:

The first step: Select the working directory. All of the code written later on Eclipse is on the working directory.

Step Two: Create a project on the Project Exploer window, and we will write the code in the future as an engineering unit.

Steps to create a new project:

Project Exploer window Right-click----------> New---------> Java Project

Step Three: Right-click in the SRC directory of the project and create a class on the new class.

Catalog description of the project:

Settings:elcipse automatically generated configuration files. Don't touch it.

Bin: For storing all the class files.

SRC: Used to store all Java source files.

Fourth step: Run the Java file.

Mode one: Java source right-click-------->run as-----------> Java application

Way two: Green Arrow--------->run as-----------> Java application

Mode three: Shortcut key operation: Ctrl + F11

Fifth Step: Import Project:

Package Cn.itcast.eclipse;import java.io.file;/* using Eclipse benefits: 1. CTRL +/Inner completion. 2. You do not need to use the Javac tool to compile, and once you save on Eclipse, Eclipse automatically compiles. 3. Accurate error, automatic repair (CTRL + 1). */public class Demo1 {public static void main (string[] args) {File file = new file ("F:\\a.txt"); System.out.println ("AAA"); System.out.println ("Hello World");}}
