java獲取vm運行參數

To get the version of running VM (Virtual Machine) in Java, we use the getProperties() method, which is defined in System class, while calling the method, we need to pass the property name to get the version of running Java VM.

要獲取Java中正在運行的VM(虛擬機)的版本 ，我們使用System類中定義的getProperties()方法 ，在調用該方法時，我們需要傳遞屬性名稱以獲取正在運行的Java VM的版本。

The property to get the running Java VM version: "java.vm.version"

獲取正在運行的Java VM版本的屬性： “ java.vm.version”

The method call is: System.getProperties("java.vm.version");

方法調用為： System.getProperties(“ java.vm.version”);
