Hi Ricardo,
Try the following code :
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Properties;
public class SetSystemProperties {
public static void main(String[] args) throws IOException {
FileInputStream propFile = null;
try {
propFile = new
FileInputStream("myProperties.txt");\\Please specify
your file path here
Properties p = new Properties();
p.load(propFile);
p.setProperty("myKey1", "myValue1");
System.out.println(p.getProperty("subliminal.message"));
System.out.println(p.getProperty("myown.property"));
System.out.println(p.getProperty("myKey1"));
throw new IOException(); // I added this code to throw
an
IOException explicitly , remove this for your code.This
// is
just for showing how exception is caught
} catch (FileNotFoundException e) {
System.out.println("File not found in the place");
e.printStackTrace();
} catch (IOException e) {
System.out.println("IO Exception Occured");
e.printStackTrace();
} catch (Exception e) {
System.out.println("Some exception has occured");
e.printStackTrace();
} finally {
if (propFile != null) {
System.out.println("Closing FileInputStream");
propFile.close();
} else {
System.out.println("FileInputStream not open");
}
}
}
}
which defines the code which handles specific exceptions and also
closes the File stream opened.
Remember for an application that reads / writes files its more
important to close your streams.
Thanks,
Ashok A V
