Java 程序获取操作系统的名称和版本

Java instance大全

In this example, we will learn how to use Java programs to get the current name and version of the operating system.

Example: Java to get the name and version of the operating system

class Main {
　　public static void main(String[] args) {
　　　　//Get the name of the operating system
　　　　String operatingSystem = System.getProperty("os.name");
　　　　System.out.println(operatingSystem);
　　}
}

Output result

Windows　10

In the above example, we used the getProperty() method of the System class. Here, we pass the os.name key as a parameter to this method.

This method returns the system property specified by the key.

There are other keys that can be used to obtain other system properties. For example,

//Return the version of the operating system
//　10.0
System.getProperty("os.version");

Here, the key os.version returns the version of the operating system.
