Setting and getting System Properties in Java

To set the System property

System.setProperty("p1","v1");

Loading System properties from a settings file say xyz.properties

Properties prop = new Properties();

try {
InputStream inputStream = URLReader.class.getClassLoader().

getResourceAsStream("xyz.properties");
prop.load(inputStream);
} catch (IOException ex) {

}

Reading System property

System.getProperty("os.name")
System.getProperty("user.dir");

Similarly we can read user.timezone, user.home, java.version, file.separator

Reading all System properties

System.getProperties().list(System.out);
