为什么我的 JRE 位于 C:\Program Files (x86) 虽然它是 64 位版本？
[英]Why my JRE is in C:\Program Files (x86) although it's a 64-Bit build?
问题描述
I downloaded JRE first.
我先下载了JRE。 Then downloaded JDK.然后下载JDK。
My JRE is in this directory我的 JRE 在这个目录中
C:\Program Files (x86)\Java\jre1.8.0_291
My JDK is in this directory我的 JDK 在这个目录中
C:\Program Files\Java\jdk-16.0.1
Running java -version command yields the following:运行java -version命令产生以下结果：
C:\Program Files (x86)\Java\jre1.8.0_291\bin>java -version
java version "1.8.0_291"
Java(TM) SE Runtime Environment (build 1.8.0_291-b10)
Java HotSpot(TM) Client VM (build 25.291-b10, mixed mode, sharing)
C:\Program Files\Java\jdk-16.0.1\bin>java -version
java version "16.0.1" 2021-04-20
Java(TM) SE Runtime Environment (build 16.0.1+9-24)
Java HotSpot(TM) 64-Bit Server VM (build 16.0.1+9-24, mixed mode, sharing)
does that mean I have a duplicate JRE?这是否意味着我有一个重复的 JRE？
If so, why there is no JRE in C:\Program Files\Java\ ?如果是这样，为什么C:\Program Files\Java\中没有 JRE？

"If you want to run Java programs, but not develop them, download the JRE. If you want to develop Java applications, download the Java Development Kit, or JDK. The JDK includes the JRE, so you do not have to download both separately." "If you want to run Java programs, but not develop them, download the JRE.
