Question

我最近在运行Windows 10的计算机上下载了Java SDK 8.0。但是，当我在Internet上查看如何在Windows 10命令提示符中使用Java时，我只能获得var vm = this; vm.dashboardGlobals = globalContainer.dashboardGlobals; var dataFactory = new abstractDataFactory("/odata/ProjectList"); var projectController = new abstractDataFactory("/Projects/ChangeCurrentProject") // load up projectDashboardDTO vm.projectList = []; . . . dataFactory.getList("") // no parameters .success(function (result) { vm.projectList = result.value; vm.dashboardGlobals.projectList = result.value; vm.selectProjectPlaceholder = "Select a project . . . "命令在提示中工作。当我尝试运行我的程序时，命令提示符说它找不到javac文件。有谁知道如何让Java在Windows 10中运行？（我使用的是x86版本的Java。）

Answer 1

打开命令提示符cmd并输入where java，这将输出java可执行文件的位置，然后您可以转到System Propreties>Advanced>Environement Variables> （右键单击计算机并单击Propreties） 并将where java输出添加到用{em>分号 PATH分隔的;变量

Answer 2

Java实际上不必安装。您可以运行任何可用的Java。

这对于从网络共享运行Java有用。

尝试通过完全限定来运行java.exe程序。如果它以这种方式运行，则问题出在PATH上。

为了说明你可以通过限定运行任何Java，我安装了9个JDK和1个JRE：

32位JDK：版本1.4,5,6,7和8
64位JDK：版本5,6,7和8
32位JRE：版本8

从单个命令提示符窗口复制：
