How to test for Windows 7 platform?

Question

I have a Java app which needs to run differently when on Windows 7.

How would you check which Windows version is present? Is it enough to check for OS version 6.1?

Answer 1

I've solved the same problem checking also for os.name, in a null-safe way:

public boolean runningOnWindows7() {
    String osName = System.getProperty("os.name");
    String osVersion = System.getProperty("os.version");
    return "Windows 7".equals(osName) && "6.1".equals(osVersion);
}
