Java programa obter o nome e a versão do sistema operacional

Java Examples

In this example, we will learn how to use a Java program to get the current operating system's name and version.

Example: java get the name and version of the operating system

class Main {
　　public static void main(String[] args) {
　　　　//Get the operating system's name
　　　　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 get other system properties. For example,

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

Here, the key os.version returns the operating system's version.
