First you should have Java 7. If you don't have, install it first (I don't know what you are using, Linux, Mac, yum, apt, homebrew, you should find out yourself.)

首先你应该有Java 7。如果你没有，先安装它（我不知道你在用什么，Linux，Mac，yum，apt，homebrew，你应该自己找出来。）

If you already have Java 7, run:

如果您已经拥有 Java 7，请运行：

echo $JAVA_HOME

Output should be something like this:/usr/lib/jvm/java-8-oracle. Near this directory, you should see java-7directory. After you found it, run

输出应该是这样的：/usr/lib/jvm/java-8-oracle. 在此目录附近，您应该会看到java-7目录。找到后，运行

export JAVA_HOME=${java-7-dir}

Change {java-7-dir}with your directory path. Then you can run your command.

更改{java-7-dir}您的目录路径。然后你可以运行你的命令。

This is only a temporary solution.To change it permanently, put the above command to your ~/.bashrcfile.

这只是一个临时解决方案。要永久更改它，请将上述命令放入您的~/.bashrc文件中。

EDIT: If you are using Windows, change environment variable of JAVA_HOMEto your Java 7 installation directory path.

编辑：如果您使用的是 Windows，JAVA_HOME请将环境变量 of 更改为您的 Java 7 安装目录路径。

My short contribution, for sharing the same problem with Talend Open Studio 64 bit version.

我的简短贡献，用于分享与 Talend Open Studio 64 位版本相同的问题。

1. Launch ..\TOS_DI-Win32-20150702_1326-V6.0.0\TOS_DI-win-x86_64.exe manually (not link an startup Windows menu)
2. and this registry error message appears

1. 手动启动 ..\TOS_DI-Win32-20150702_1326-V6.0.0\TOS_DI-win-x86_64.exe（不链接启动 Windows 菜单）
2. 并出现此注册表错误消息

To resolve this, remove all java.exe, javaw.exe and javaws.exe files on c:\ProgramData\Oracle\Java\javapath\

要解决此问题，请删除 c:\ProgramData\Oracle\Java\javapath\ 上的所有 java.exe、javaw.exe 和 javaws.exe 文件

and TOS start with 64 bits version correctly !

和 TOS 以 64 位版本正确开始！

In my case (Windows 7 64-bit), I just did the following:

就我而言（Windows 7 64 位），我只执行了以下操作：

• Removed the reference to C:\ProgramData\Oracle\Java\javapath;from the Pathenvironment variable
• Removed files java, javawand javawsfrom the C:\Windows\System32folder

• 删除了对C:\ProgramData\Oracle\Java\javapath 的引用；来自Path环境变量
• 从C:\Windows\System32文件夹中删除文件java、javaw和javaws

Afterwards, I closed all open command line consoles, reopened them and ran java -version.

之后，我关闭了所有打开的命令行控制台，重新打开它们并运行java -version。

Remove it from the System path:

从系统路径中删除它：

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem

And it will fix the issue in upgrading java version from 1.7 to 1.8

它将解决将 Java 版本从 1.7 升级到 1.8 的问题

aribeiro answer has worked for me - with minor changes

aribeiro 的答案对我有用 - 稍作改动

• I Removed the reference to C:\ProgramData\Oracle\Java\javapath; from the Path environment variable
• I made /path/to/jdkhome as the first entry in my PATH environment variable. I think this alone is all that is needed.

• 我删除了对 C:\ProgramData\Oracle\Java\javapath 的引用；来自 Path 环境变量
• 我将 /path/to/jdkhome 作为 PATH 环境变量中的第一个条目。我认为仅此一点就足够了。

I've had the same problem. Simple solution that worked for me is to rearrange the entries in the PATHfor JRE/JDK. This problem started to appear after installing JRE 8whose installation has put some executable files in System32 or SysWOW64directories, these executable files are messing up. To resolve the problem:

我遇到了同样的问题。对我有用的简单解决方案是重新排列PATHfor 中的条目JRE/JDK。安装后开始出现这个问题，JRE 8其安装System32 or SysWOW64目录中有一些可执行文件，这些可执行文件乱七八糟。要解决问题：

1. Create environment variable pointing to JDK home as JAVA_HOME.

   set JAVA_HOME=C:\Progra~1\Java\jdk1.8.0_45

2. Put the entry %JAVA_HOME%\binat start in your PATH environment variable. Appending existing value of PATH. For example:

   path=C:\Program Files\Java\jdk1.8.0_45\bin;%path%

1. 创建指向 JDK home 的环境变量作为JAVA_HOME.

   set JAVA_HOME=C:\Progra~1\Java\jdk1.8.0_45

2. 将条目%JAVA_HOME%\bin放在 PATH 环境变量中。附加 的现有值PATH。例如：

   path=C:\Program Files\Java\jdk1.8.0_45\bin;%path%

1. open regedit
2. go to [HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment]
3. change value CurrentVersionfrom "1.8" to "1.7"

re: Windows users

回复：Windows 用户

No. Don't remove the Javapath environment reference from your PATH variable.

不。不要从 PATH 变量中删除 Javapath 环境引用。

The reason why the registry didn't work is that the Oracle Javapath script needs to run in the PATH sequence ahead of the JRE & JDK directories - it will sort out the current version:

注册表不工作的原因是Oracle Javapath脚本需要在JRE & JDK目录之前的PATH序列中运行——它会整理当前版本：

put this directory at the HEAD of your %PATH%variable:

将此目录放在%PATH%变量的 HEAD 中：

C:\ProgramData\Oracle\Java\javapath

[or wherever it is on your desktop]

[或桌面上的任何位置]

so your PATH will look something like this - mine for example

所以你的路径看起来像这样 - 例如我的

PATH=C:\ProgramData\Oracle\Java\javapath;<other path directories>;E:\Program Files\Java\jdk1.8.0_77\bin;E:\Program Files\Java\jre1.8.0_77\bin

You will then see the correct, current version:

然后，您将看到正确的当前版本：

C:\>java -version
java version "1.8.0_77"
Java(TM) SE Runtime Environment (build 1.8.0_77-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)
