Java版本切换

在A:\DevEnvironment\javaVersion目录下，创建Windows命令脚本

Java8.bat

@echo off
 set JAVA_HOME=A:\DevEnvironment\jdk-1.80_152
 set Path=%JAVA_HOME%\bin;%Path%
 echo Version has been switched to Java 8.

Java11.bat

@echo off
 set JAVA_HOME=A:\DevEnvironment\jdk-11.0.16.1
 set Path=%JAVA_HOME%\bin;%Path%
 echo Version has been switched to Java 11.

java17.bat

@echo off
 set JAVA_HOME=A:\DevEnvironment\jdk-17.0.6
 set Path=%JAVA_HOME%\bin;%Path%
 echo Version has been switched to Java 17.

将脚本的路径，配置在环境变量上

A:\DevEnvironment\javaVersion

效果
