更改java版本的Windows [英] change java version windows

问题描述

我的笔记本电脑是64位。但是对于某些基本软件，我有java 7 update 11（32位）。现在，我需要java 8（64位）和eclipse mars（64位）才能工作。我无法将版本从java 7（x86）更改为java 8（64）。我不想删除32位java，也可以使用java 8，64位。
我已经包括路径系统变量内容。我是初学者将不胜感激，如果您不写GLIB和嘲弄的评论。

我不是在寻找任何批处理脚本的答案。可以使用GUI吗？

我的eclipse.ini

  -startupplugins /org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar--launcher.libraryplugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.300.v20150602-1417-productorg.eclipse.epp.package。 jee.product  -  launcher.defaultActionopenFile  -  launcher.XXMaxPermSize256M-showsplashorg.eclipse.platform  -  launcher.XXMaxPermSize256m  -  launcher.defaultActionopenFile  -  launcher.appendVmargs-vmargs-Dosgi.requiredJavaVersion = 1.7-Xms256m-Xmx1024m-vm C： \Program Files\Java\jre1.8.0_91\bin\\ javaw.exe  

解决方案

你添加到eclipse.ini

  -vm C：\Program Files\Java\jre1.8.0_91\bin \javaw.exe 
  

但应该

  -vm 
 C：\Program Files\Java\jre1.8.0_91\bin\javaw.exe 
  

之间必须有一条新行。你确定要使用JRE而不是JDK吗？

尝试这样一个ini

  -startupplugins / org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar  -  launcher.libraryplugins / org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.300.v20150602-1417-productorg.eclipse。 epp.package.jee.product  -  launcher.defaultActionopenFile  -  launcher.XXMaxPermSize256M-showsplashorg.eclipse.platform  -  launcher.XXMaxPermSize256m  -  launcher.defaultActionopenFile  -  launcher.appendVmargs-vm C：\Program Files\Java\\ \\jre1.8.0_91\bin\javaw.exe-vmargs-Dosgi.requiredJavaVersion = 1.7 Xms256m-Xmx1024m  

My laptop is 64 bit. But I have java 7 update 11(32 bit) for certain essential softwares. Now, i need java 8 (64 bit) and eclipse mars (64 bit) to work. I am unable to change version from java 7(x86) to java 8(64). I do not want to remove 32 bit java and also work with java 8, 64 bit. I have included the path system variable contents. I am a beginner. will appreciate if you do not write GLIB and derisive comments.

I am not looking for any batch scripts answers. Can it be done using GUI?

My eclipse.ini

-startup
plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.300.v20150602-1417
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.7
-Xms256m
-Xmx1024m

-vm C:\Program Files\Java\jre1.8.0_91\bin\javaw.exe

解决方案

You added to eclipse.ini

-vm C:\Program Files\Java\jre1.8.0_91\bin\javaw.exe

but should

-vm
C:\Program Files\Java\jre1.8.0_91\bin\javaw.exe

There must be a new line between. Are you sure you want to use JRE instead of JDK?

Try such an ini

-startup
plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.300.v20150602-1417
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vm 
C:\Program Files\Java\jre1.8.0_91\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.7
-Xms256m
-Xmx1024m
