如何使您的计算机更改Java路径 [英] How to Make Your Computer Change Java Path

问题描述

不久前，我为游戏模块安装了一些.jar文件，这些文件似乎已在计算机上安装了1.8 JRE.现在，我安装了JDK 14，但是，我的计算机仍然认为我的Java版本是1.8.我的计算机上有两个Java文件夹-一个包含在JDK的程序文件中，一个存在于旧JRE的程序文件(x86)中.

So a while back I installed some .jar files for game mods, which seems to have installed the 1.8 JRE on my computer. Now, I installed JDK 14, however, my computer still thinks that my Java version is 1.8. I have two Java folders on my computer - one in Program Files with the JDK, and one in Program Files (x86) with the old JRE.

我将JAVA_HOME环境变量设置为JDK的目录，但是当我在命令提示符中键入 java -version 时，它仍显示为1.8.如何让我的计算机从JDK 14运行Java?

I set the JAVA_HOME environment variable to the directory of the JDK but when I type java -version in my Command Prompt it still says 1.8. How do I get my computer to run Java from JDK 14?

*很抱歉，如果这没有什么意义，我仍然对计算机的工作方式不甚了解.

*Apologies if this doesn't make much sense, I still don't know much about how computers work.

推荐答案

我假设您使用的是基于Program Files(x86)文件夹的Windows.可以说是Windows 10.

I'm assuming you are using Windows based on Program Files (x86) folder. Let say it is Windows 10.

转到环境变量，系统变量部分.

Go to environment variable, system variables section.

1. 将 CLASS 的值更改为... \ java14 \ bin
2. 将 classpath 的值更改为... \ java14 \ lib \ * .jar
3. 将 JAVA_HOME 的值更改为... \ java14
4. 将 PATH 的值更改为... \ java14 \ bin(确保将其移至顶部)

1. change CLASS value to ...\java14\bin
2. change classpath value to ...\java14\lib\ *.jar
3. change JAVA_HOME value to ...\java14
4. change PATH value to ...\java14\bin (be sure to move this up to the top)

将您的 jdk 文件夹的名称替换为 java14 现在，它应该可以按预期执行. javac 将是第14版， java 也将是第14版.

Substitute the name of your jdk folder to java14 Now it should perform as expected. javac will be version 14, java will be version 14 too.
