Java Environment Configuration-eclipse New Project

Configure the installation JDK and JRE first

Install the following:

Then configure the variable environment: Right-click My Computer--Properties--Advanced system settings--environment variables--system variables--Find path--Edit

Put the directory of the JDK that is installed and the bin directory under the JDK directory

Example: C:\java\jdk1.8.0_111; C:\java\jdk1.8.0_111\bin, because the directory where I installed the JDK is installed directly under the C drive.

Next configure the variable environment lib (that is, library): Right-click My Computer--Properties--Advanced system settings--environment variables--System variables--new Classpath

Put the directory of the installed JDK and the directories of the JDK to scare the Lib directory into it

Example: C:\java\jdk1.8.0_111; C:\java\jdk1.8.0_111\lib;

Tip: If you find these directories difficult to distinguish, you can put the root directory and bin and the Lib directory under path and classpath, do not conflict.

Continue, install Eclipse.

Then: File--New--java Project

Then right--new--Class

Select options as shown in the diagram.
