How to know the OS Name and Version using Java Code


To know about the OS version and name on which your Java code is executed make use of os.name and os.version system properties.

Example:
package org.code2care.javaexamples;

/**
 * 
 * How to know the Java OS Details 
 * using Java system property 
 * os.version
 * os.name
 * 
 * 
 * @author code2care
 *
 */
public class JavaOSDetailsExample {

	public static void main(String[] args) {
		
		System.out.println("OS Name: " + getOSName());
		System.out.println("OS Version: " + getOSVersion());
	
	}
	
	
	public static String getOSName() {
		return System.getProperty("os.name");
	}
	
	
	public static String getOSVersion() {
		return System.getProperty("os.version");
	}

}
Output
