What's the point of setting the initial properties to those in
"myProperties.txt"? And is it required in the Homework assignment?
import java.io.FileInputStream;
import java.util.Properties;
public class SetSystemProperties {
public static void main(String[] args) throws Exception {
// set up new properties object
// from file "myProperties.txt"
FileInputStream propFile = new FileInputStream(
"myProperties.txt");
Properties p = new Properties(System.getProperties());
p.load(propFile);
// set a property through setProperty() method
p.setProperty("myKey1", "myValue1");
// set the system properties
System.setProperties(p);
// display new properties
System.getProperties().list(System.out);
}
}
