How to detect OS in Java – System.getProperty(“os.name”)
Here is a handy Java class that use System.getProperty(“os.name”) to detect which type of operating system (OS) we are using now.
public class OSValidator{
public static void main(String[] args)
{
if(isWindows()){
System.out.println("This is Windows");
}else if(isMac()){
System.out.println("This is Mac");
}else if(isUnix()){
System.out.println("This is Unix or Linux");
}else{
System.out.println("Your OS is not support!!");
}
}
public static boolean isWindows(){
String os = System.getProperty("os.name").toLowerCase();
//windows
return (os.indexOf( "win" ) >= 0);
}
public static boolean isMac(){
String os = System.getProperty("os.name").toLowerCase();
//Mac
return (os.indexOf( "mac" ) >= 0);
}
public static boolean isUnix(){
String os = System.getProperty("os.name").toLowerCase();
//linux or unix
return (os.indexOf( "nix") >=0 || os.indexOf( "nux") >=0);
}
}
