I was watching the Android development video and they asked us to install JDK and create JAVA_HOME environment variable. I already have MyEclipse installed and I previously had setup the PATH variable(giving it the directory of JDK), do I still need a JAVA_HOME variable ??? If yes then why ???

推荐答案

如果您正在使用的应用程序正在 JAVA_HOME 环境变量中寻找特定数据集，但它不存在，它是不会幸福的.

If the application you are using is looking for a specific dataset in the JAVA_HOME environment variable and it isn't there, it is not going to be happy.

其他应用程序可能会在 PATH 环境变量中查找 JDK 路径，但仅仅因为您在那里拥有它并不意味着它适用于需要它在单独变量中的其他应用程序.

Other applications might look for the JDK path in the PATH environment variable, but just because you have it there doesn't mean it will work for other applications that need it in a separate variable.
