How to Check Operating System Type Using Java

There are several System properties which can be accessed using System.getProperty("property_name") where os.name is one of those properties.

The below code help us identify the operating system of Java Virtual Machine (JVM) using System.getProperty("os.name").

package com.learning;

import java.util.Locale;

public class OperatingSystem {

	private static final String OS = System.getProperty("os.name").toLowerCase(Locale.ENGLISH);

	public static final String WINDOWS_OS = "windows";
	public static final String MAC_OS = "mac";
	public static final String UNIX_LINUX_OS = "unixLinux";
	public static final String SOLARIS_OS = "solaris";

	public static boolean isWindows() {
		return OS.contains("win");
	}

	public static boolean isMac() {
		return OS.contains("mac");
	}

	public static boolean isUnix() {
		return (OS.contains("nix") || OS.contains("nux") || OS.contains("aix"));
	}

	public static boolean isSolaris() {
		return OS.contains("sunos");
	}
	
	
	public static void main(String args[]) {
		
		getOperatingSystemType();
		
	}

	public static String getOperatingSystemType() {
		if (isWindows()) {
			System.out.println("************** Windows OS Detected ***************");
			return WINDOWS_OS;
		} else if (isMac()) {
			System.out.println("************** Mac OS Detected ***************");
			return MAC_OS;
		} else if (isUnix()) {
			System.out.println("************** Unix or Linux OS Detected ***************");
			return UNIX_LINUX_OS;
		} else if (isSolaris()) {
			System.out.println("************** Solaris OS Detected ***************");
			return SOLARIS_OS;
		} 
		return null;
	}

}

After executing the above code on Windows Operating System Machine the below output is generated.

************** Windows OS Detected ***************
